˜q™é‡Œè¯´æ˜Žä¸€ä¸‹æ›¾¾lå‘生过的事情：

开始的éºÈƒ¦

1. 思维转变

敏捷讲的全是当下的考量、当前的冲刺、当前的用户故事½{‰ã€‚当一路走来突然有其他某个故事出现在面前的时候，我们òq¶ä¸ä¼šäº‹å…ˆè€ƒè™‘事情ž®†å¦‚何发展。过åŽ? 在瀑布模型里，我们常常是首先考虑整个¾pȝ»ŸåQŒHLDåQˆé«˜å±‚设计）和LLDåQˆä½Žå±‚设计）是第一步，在ç‘ô¾l­å‰˜q›ä¹‹å‰ï¼Œå®ƒä»¬å¿…é¡»å†È»“ã€?/p>

2. 持箋换档

敏捷是一个不断变化的环境ã€?#8220;响应变化”是其ä¸Õd¯¼åŽŸåˆ™ä¹‹ä¸€ã€‚äؓ了响应，开发者必™å»è·Ÿå¸‚面上的技术保持同步，否则它将让你异常痛苦ã€?/p>

我们面对的另一个问题是恰当地进行TDD。从技术观点看åQŒTDD已经有了不少选择。你可以依赖不同的模拟和‹¹‹è¯•æ¡†æž¶åQŒè¿™äº›å¾€å¾€éƒ½æ˜¯ä½ åœ¨ç€‘布模型里不使用的东è¥Ñ€‚要是你想采用TDDåQŒé‚£ä¹ˆå°±å¿…须具备对它们的丰富知识åQŒå¦åˆ™æ•´ä¸ªè¿‡½E‹å°±ä¸ä¼šå¤ªé¡ºåˆ©ã€?/p>

¾~“慢地冲åˆ?/h2>

1. ‹¹‹è¯•é©±åŠ¨å¼€å‘说的是先写‹¹‹è¯•åQŒç„¶åŽç”±‹¹‹è¯•å¯¼å‡ºä¸šåŠ¡é€»è¾‘。这是最éšùN€‚应的事情之一åQŒå› ä¸ºå®ƒå®Œå…¨é¢ è¦†äº†ä½ çš„观å¿üc€?

   在瀑布模型里，æ€ÀL˜¯ä»£ç å…ˆå®Œæˆï¼Œç„¶åŽå†è¿›è¡Œäº›‹¹‹è¯•åQˆé€šå¸¸éƒ½æœ‰åQŒä½†òq‰™žæ€ÀL˜¯æœ‰ï¼‰åQ›ä½†TDD则完全是¾U¢ã€ç»¿å’Œé‡æž„。这¿Uæ–¹æ³•è¦æ±‚我们用抽象术语 ˜q›è¡Œæ€è€ƒï¼Œç„¶åŽç”±å®ƒä»¬æ¼”变出具体的事物。由于一开始难以适应åQŒæˆ‘们往往求助于先写出逻辑åQŒç„¶åŽç¡®ä¿å­˜åœ¨è¦†ç›–它们的‹¹‹è¯•ã€‚我把这¿UîCؓ开发驱动测试（DDTåQ? æ–ÒŽ³•ã€?/p>

   DDTòq¶æ²¡æœ‰å¢žåŠ å¤ªå¤šçš„意义。假如你知道你的代码ž®†ä¼šå¾ˆå¥½åœ°å·¥ä½œï¼Œé‚£äؓ何还要写个测试呢åQŸåªæ˜¯è¦è¯æ˜Ž˜q™æ®µä»£ç ¼‹®å®žæœ‰æ•ˆåQŸåº”该不止这一炏V€‚çš„¼‹®æ˜¯˜q™æ ·ã€‚例如，写测试可以让你的代码在耦合性方面表现更好，而且˜q˜èƒ½å¤ŸäØ“ž®†æ¥çš„代码变更提供一个巨大的安全¾|‘ã€?/p>

2. 在敏捷里åQŒä»¥æŠ½è±¡æœ¯è¯­˜q›è¡Œæ€è€ƒæ˜¯å¼€å‘äh员必™åÕd…·å¤‡çš„技能。在敏捷中我们åƈ不像瀑布模型那样˜q›è¡Œé¢„先设计åQŒé€šè¿‡åˆ›å¾æŠ½è±¡å’Œå¼€å‘工作流åQŒè®¾è®¡åˆ°äº†ä¸€å®šçš„时候自然就会现íw«ã€‚敏捷中的开发äh员必™å»è‡³ž®‘精通基本的设计模式åQŒå¦åˆ™ä»–们将产生一大堆垃圾代码åQŒä»Žä¸­åªèƒ½å¾—出拙劣的设计ã€?

   TDD在这里对我们大有帮助。它要求我们按抽象术语进行思考。此外，只要我们开始修æ”ÒŽµ‹è¯•ï¼Œæˆ‘们ž®±å¿…™å»è€ƒè™‘˜q›è¡Œé‡æž„åQŒè®©æˆ‘们的代码变得更 好。DDT也能帮助我们立即识别ä»ÖM½•è´¨é‡é—®é¢˜åQŒè¿™æ ·å®ƒä»¬å°±èƒ½åŠæ—¶åœ°å¾—到修复。这æ øP¼Œæˆ‘们最¾lˆè®¤è¯†åˆ°å¿…须抛弃“首先¾~–代码，然后写测è¯?#8221;的套路，后来我们é‡? 新开始采用了TDDæ–ÒŽ³•ã€?/p>

3. 代码质量是团队的职责åQŒå›¢é˜Ÿæˆå‘˜å°†æ—¶ä¸æ—¶çš„重构代码或者可能会重新¾~–写åQŒç›´åˆ°å®ƒ½W¦åˆé¢„先制订的标准。我们不要把ä»ÖM½•æƒ…çÈA跟我们的代码兌™” èµäh¥åQŒåº”该准备不断地抛弃或重写它。遵循Venkat Subramaniam在集体所有制实践斚w¢çš„徏议：“每次执行‹‚€å…¥ä»£ç æ“ä½œæ—¶åQŒæˆ‘们都应该致力于改善代码的质量ã€?#8221;

4. 在瀑布模型里，需求是要签字的åQŒæœ‰ç‚¹åƒè¡€èª“，然后你再¾l§ç®‹å‘前¿UÕdŠ¨ã€‚但在敏捷里åQŒéœ€æ±‚与解决æ–ÒŽ¡ˆåŒæ­¥æ¼”变。这帮助我们在前˜q›çš„˜q‡ç¨‹ä¸­è®©äº? 情变得越来越清晰åQŒä½†˜q™ä¹Ÿå¯ÆD‡´¾pȝ»Ÿéœ€è¦ä¸æ—¶çš„重新设计åQŒåœ¨æœ€åˆçš„冲刺åQ?-4åQ‰é‡ŒåQŒè¿™¿Uæƒ…å†ëŠ»å¸æ€¼šå‘生。此外，Backlog也能在冲刺的中间改变åQŒå›  此，团队应该æ ÒŽ®˜q™äº›å˜åŒ–˜q›è¡Œè°ƒæ•´åQŒå› ä¸ºåœ¨æ¯ä¸ªå†²åˆº¾l“束时交付可工作的èÊY件是敏捷的åñ”右铭ã€?/li>

5. ¾l“对一开始让äºø™§‰å¾—是‹¹ªè´¹æ—‰™—´å’Œç²¾åŠ›ã€‚两äºÞZ¸€èµ·åœ¨åŒä¸€æ•…事上进行工作就像是各浪费了一半的旉™—´å’Œç²¾åŠ›ã€‚而且åQŒå¤šäººå®ŒæˆåŒä¸€æ•…事的不同ä“Q务似乎是å¯ÆD‡´é€Ÿåº¦ä¸‹é™çš„原因ã€?

6. 在采用TDDæ—Óž¼Œ¾l“对的效果最好。Driverå’ŒNavigator一起努力开发更好的¾pȝ»Ÿã€‚但如果你是按照DDT的方式进行结对编½E‹ï¼Œ 那它ž®×ƒ¸æ˜¯æœ€ä½³çš„前进之èµ\。在˜q™ç§æƒ…况下，两个合作者都不会知道该如何前˜q›ï¼Œä¾‹å¦‚¾pȝ»Ÿè®¾è®¡åº”该像什么样子，˜q™æ ·ä½ å°†å¾—到很多噪音åQŒäñ”生最¾lˆå¿…™å»é‡å†™çš„一å ? 源代码文件ã€?

   遵åó@TDD是最佳的方式åQŒä½†è¦æ˜¯ä½ è¿˜æ²¡æœ‰é€‚应它，你仍然可以结对：利用一块玻璃（白）板，首先ç”Õd‡ºæŸä¸ªè®¾è®¡‹¹ç¨‹å›¾ï¼Œç„¶åŽå…¶ä¸­ä¸€ä¸ªåˆä½œè€…可以编写代码，而另一个则可以¾~–写‹¹‹è¯•ç”¨ä¾‹ã€?/p>

   当个别故事全部完工而某些没有，˜q™æ ·çš„冲刺算不算成功呢？那假如冲刺的全部故事基本完成但还有些烦äh的小问题呢？

   团队应该å…Ïx³¨è®©æ•´ä¸ªæ•…事完工，所有问题得到解冻I¼Œòq¶ä¸”满èƒö完工标准åQ›è€Œä¸æ˜¯æ…Œæ…Œå¼ å¼ åœ°ç›¯ç€Backlog马虎了事。一‹Æ¡å®žæ–½è¹©è„šçš„冲刺没有 ä»ÖM½•æ„ä¹‰åQŒé™¤äº†åœ¨¾l§ç®‹å‰è¿›ä¹‹å‰å¿…é¡»ž®†å·²å®Œæˆçš„事情返工。时间常常是一个约束条ä»Óž¼Œå› æ­¤æ ÒŽ®æ•…事的相寚w‡è¦ç¨‹åº¦ï¼Œå›¢é˜Ÿåº”该扑ևºä¸€¿Uå¯¹ä»–们提议的解å†Ïx–¹æ¡ˆæ›´å…? 质量意义的实施方法。位于Backlog™å¶ç«¯çš„故事必™åÕd°½é‡ä»¥æœ€å¥½çš„方式开发解冻I¼Œéšç€æˆ‘们逐渐¿UÕdŠ¨åˆ°Backlog的底部，对解å†Ïx–¹æ¡ˆçš„质量可能会有äº? 妥协åQŒä½†òq¶ä¸æ˜¯å¯¹å®Œå·¥æ ‡å‡†è€Œè¨€ã€‚对于故事的实现åQŒæ›´å¥½çš„方式是宁¾~ºå‹¿æ»¥ã€?/p>

10. 计划会议肯定是费脑子和让人精疲力竭的‹zÕd„¿ã€‚坐在椅子里4个钟头确定故事点数就像是在玩轮盘赌。这些数字将军_®šåŒ…含在冲刺里的内容，但是怎样在你æ ÒŽœ¬æ²¡æœ‰¾léªŒçš„时候决定数字呢åQŸä½ ä¸€å®šä¼šä¼°è®¡é”™è¯¯ã€?

11. 分配故事ç‚ÒŽ•°æ˜¯ä¸€ä¸ªå¤æ‚çš„ä»ÕdŠ¡åQŒåº”该按阶段完成。团队内部应该首先分析故事，òq¶ä¸Žäº§å“è´Ÿè´£äºø™¿›è¡Œè®¨è®ÞZ»¥æ¸…æ™°åœîCº†è§£éœ€æ±‚。在得到清晰的视å›? 之后åQŒå°±è¦è¿›è¡Œå¹¿æ³›çš„技术讨论，考虑可以实现的最佛_¯èƒ½è§£å†Ïx–¹æ¡ˆã€‚这步要是完成不好，ž®†å¯¼è‡´åœ¨æ•…事应该如何实现斚w¢æ¨¡æ£±ä¸¤å¯åQŒè¿›è€Œå¯¼è‡´æœ‰¾~ºé™·çš„估计。假 设，如果某个故事接触åˆîCº†ä¸€ä¸ªæ–°çš„未探烦领域åQŒé‚£ä¹ˆå®ƒåº”该会相当复杂，即便它是一个简单的ä»ÕdŠ¡ã€‚即使在已知领域åQŒæŠ€æœ¯è§£å†Ïx–¹æ¡ˆçš„不同也会å¯ÆD‡´æ•…事相当å¤? 杂ã€?

This platform is intended to allow developers of free apps to earn on their apps showing advertisement. The main idea of iAd is to connect interactivity (using smartphone or tablet) and emotionality of advertisement (JavaScript, HTML5, CSS3, multi-touch). It allows to create absolutely awesome advertisement which looks like apps with video and audio. In addition, iAd ads is opened inside the app and user do not exit his app and can get back anytime he wants.

Below is the guide on how to add iAd banner into iPhone app. Guide is based on iAd Programming Guide and WWDC 2010 video.

Add iAd Banner to iPhone App

The first thing you need to do is to add iAd.framework in your Xcode project which is contained in iOS 4 SDK. Also do not forget to add #import <iAd/iAD.h>. Developers can choose between two banners: 320×50 px for portrait and 480×32 px for landscape. The base of banner is ADBannerView, which is subclass of UIView. So the only thing you have to do is to add this view in your control elements hierarchy (you can do this programmatically or using Interface Builder).

Apple recommends to put banner at the bottom or at the top of the window and do not place it on any moving elements like ScrollView or TableView as far as that will decrease shows of banner (and your revenue respectively) and will make it more difficult for user to tap on the ads.

Let’s create a new project in Xcode using View-based Application template and add a banner into it. Name of the app – iAdEx. We are going to edit iAdExViewController.h

?

1 2 3 4 5 6 7 8 9 10

#import <UIKit/UIKit.h>; #import <iAd/iAd.h>;   @interface iAdExViewController : UIViewController <ADBannerViewDelegate> {       ADBannerView *adView;       BOOL bannerIsVisible; } @property (nonatomic,assign) BOOL bannerIsVisible; @end

and modify viewDidLoad method in iAdExViewController.m

?

1 2 3 4 5 6 7 8 9 10

- (void)viewDidLoad {       adView = [[ADBannerView alloc] initWithFrame:CGRectZero];       adView.frame = CGRectOffset(adView.frame, 0, -50);       adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifier320x50];       adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifier320x50;       [self.view addSubview:adView];       adView.delegate=self;       self.bannerIsVisible=NO;       [super viewDidLoad]; }

Let’s talk about requiredContentSizeIdentifiers and currentContentSizeIdentifier properties. In the first one you define all types of banners you are going to use. And the second property defines which type of banner you are going to use at the present moment.

Connection issues

Banners are downloaded from the network. What if we have no network connection right now? Or Apple has any issues with ads server? Our ADBannerView will be empty is these cases. It doesn’t look very nice and wastes space on the screen. Apple recommends to do it in this way: when there is no banner for any reason remove it from the screen; when banner is received – show it again.

We have the ADBannerViewDelegate in our class and it can receive messages from banner – bannerViewDidLoadAd (when banner is loaded successfully) and didFailToReceiveAdWithError (when any problems occured). Let’s implement these messages:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

- (void)bannerViewDidLoadAd:(ADBannerView *)banner {  if (!self.bannerIsVisible)  {   [UIView beginAnimations:@"animateAdBannerOn" context:NULL]; // banner is invisible now and moved out of the screen on 50 px   banner.frame = CGRectOffset(banner.frame, 0, 50);   [UIView commitAnimations];   self.bannerIsVisible = YES;  } }   - (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error { if (self.bannerIsVisible)  {   [UIView beginAnimations:@"animateAdBannerOff" context:NULL]; // banner is visible and we move it out of the screen, due to connection issue   banner.frame = CGRectOffset(banner.frame, 0, -50);   [UIView commitAnimations];   self.bannerIsVisible = NO;  } }

It’s time to launch the app and see what we have now:

Tap the banner

And that’s it – we’ve done it in accordance with Apple’s recommendations. When we launch the app we see the banner. If we tap it, then full view of advertisement is shown. But we still have one issue…

Stop & Resume your app

In real app we should stop any application’s activity such as video, audio playback or pause game. In order to solve this task we will create two methods bannerViewActionShouldBegin (when full screen ad is shown) and bannerViewActionDidFinish (when we close ads).

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave {  NSLog(@"Banner view is beginning an ad action");  BOOL shouldExecuteAction = YES;  if (!willLeave && shouldExecuteAction)     {     // stop all interactive processes in the app     // [video pause];     // [audio pause];     }  return shouldExecuteAction; }   - (void)bannerViewActionDidFinish:(ADBannerView *)banner {    // resume everything you've stopped    // [video resume];    // [audio resume]; }

Change Orientation of iAd

What else should we do? We need to make banner change it’s orientation in accordance with iPhone position. First of all we need to change the line where we define types of banners which we will use:

?

1 2 3 4 5

- (void)viewDidLoad { ... adView.requiredContentSizeIdentifiers = [NSSet setWithObjects:ADBannerContentSizeIdentifier320x50,ADBannerContentSizeIdentifier480x32,nil]; ... }

and here are methods for changing orientation:

?

1 2 3 4 5 6 7 8 9 10 11 12

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {  // Return YES for supported orientations  return (interfaceOrientation == UIInterfaceOrientationPortrait|UIInterfaceOrientationPortrait); }   - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {  if (UIInterfaceOrientationIsLandscape(toInterfaceOrientation))   adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifier480x32;  else   adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifier320x50; }

And here is how it look in a landscape

When device changes orientation we change currentContentSizeIdentifier property of ADBannerView. Now we can see banners in landscape mode too. There is still 50 px offset, but it’s easy to fix.

Apple developers also recommend to write object.delegate=nil; line before deallocating ADBannerView object. In our example it will look like:

?

1 2 3 4 5

- (void)dealloc {  adView.delegate=nil;  [adView release];  [super dealloc]; }

Now we have finished with programming part. Good luck with Apple iAd!

There is a way of using the backBarButton with a custom action. No, it’s not by overriding the backBarButton property of navigationItem. This is not an ugly solution with images that simulate the “Back”-button (arrow-shaped.) It’s possible to use the backBarButton for popping the current viewController as normal, but than with other animations such as UIViewAnimationTransitionCurlDown.

Enough said, the solution is simple. You have to subclass your navigationController’s  popViewControllerAnimated:(BOOL)animated. So create a custom navigationController:

customNavigationController.h

#import

@interface customNavigationController : UINavigationController {}

@end

And a custom “popViewControllerAnimated:(BOOL)animated”, this popViewControllerAnimated-function uses the “UIViewAnimationTransitionCurlDown” when popping from a SettingsTableView.

customNavigationController.m

#import "customNavigationController.h"

#import "SettingsTableController.h"

 

@implementation customNavigationController

 

- (UIViewController *)popViewControllerAnimated:(BOOL)animated

{

if([[self.viewControllers lastObject] class] == [SettingsTableController class]){

 

[UIView beginAnimations:nil context:NULL];

[UIView setAnimationDuration: 1.00];

[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown

forView:self.view cache:NO];

 

UIViewController *viewController = [super popViewControllerAnimated:NO];

 

[UIView commitAnimations];

 

return viewController;

} else {

return [super popViewControllerAnimated:animated];

}

}

@end

Use your custom navigationController in your appDelegate:

customNavigationController *navigationController =

[[customNavigationController alloc] 

initWithRootViewController:rootView];

Adding features like commenting, shouts etc are very common. These type of data are usually shown
with pagination with buttons like next, previous etc.

To reduce the overhead of creating this functionality again and again we may encapsulate the common functions in a class. So did I for my applications.

I have created a class named PaginationAgent. After loading records it calls related methods of its delegate which should implement protocol PaginationAgentDeleagte.

Additionally two php files are needed. One to return the total number of records and another one is to fetch the page data. They must be named respectively as

• get_total_number_of_records.php
• get_records.php

Lets see an example.

First, I have created a simple view based project “Pagination” and designed the view as u see:

Create a similar view using Interface Builder

1. Added a button to show previous page data

2. One button to reload the data.

3. Another to show data on next page.

4. Added a UITable which will show the result.

In PaginationViewController.h, imported PaginationAgent.h file and declared:

1. PaginationAgent* objPagination;  

PaginationAgent* objPagination;

Now lets see how to initialize it. In the viewDidLoad method I initialized this like this:

view plaincopy to clipboardprint?

1. objPagination = [[PaginationAgent alloc] init];  
2. objPagination.delegate = self;  
3. objPagination.remoteApiBasePath = @"http://your.server/path/to/folder";  

objPagination = [[PaginationAgent alloc] init];
objPagination.delegate = self;
objPagination.remoteApiBasePath = @"http://your.server/path/to/folder";

remoteApiBasePath must be set to the location where the server side php files are placed.
No trailing slash.

PaginationAgentDelegate protocol declares the following functions to be overridden by the Delegate:

view plaincopy to clipboardprint?

1. /** 
2. * This method is called when the busystate is changed. 
3. * You can do something like disable/enable the buttons, grayout etc 
4. * based on the isBusy value. 
5. */  
6. -(void)paginationAgent:(PaginationAgent*)agent updateBusyMode:(BOOL)isBusy;  
7.   
8. /** 
9. * Called when total data count is received if shouldReloadAtFirstPage is set NO. 
10. */  
11. -(void)paginationAgent:(PaginationAgent*)agent totalDataCountReceived:(int)dataCount;  
12.   
13. /** 
14. * Called when page data is loaded. You may set your table dataSource here and realod 
15. * reload the table. 
16. */  
17. -(void)paginationAgent:(PaginationAgent*)agent pageDataReceived:(NSArray*)data;  
18.   
19. /** 
20. * Called if server sends malformed data 
21. */  
22. -(void)paginationAgent:(PaginationAgent*)agent onPaginationServerError:(NSString*)message;  
23.   
24. /** 
25. * Called if connection failed. It may occur due to poor or no internet connectivity 
26. */  
27. -(void)paginationAgent:(PaginationAgent*)agent onPaginationConnectionError:(NSString*)message;  

/**
* This method is called when the busystate is changed.
* You can do something like disable/enable the buttons, grayout etc
* based on the isBusy value.
*/
-(void)paginationAgent:(PaginationAgent*)agent updateBusyMode:(BOOL)isBusy;
/**
* Called when total data count is received if shouldReloadAtFirstPage is set NO.
*/
-(void)paginationAgent:(PaginationAgent*)agent totalDataCountReceived:(int)dataCount;
/**
* Called when page data is loaded. You may set your table dataSource here and realod
* reload the table.
*/
-(void)paginationAgent:(PaginationAgent*)agent pageDataReceived:(NSArray*)data;
/**
* Called if server sends malformed data
*/
-(void)paginationAgent:(PaginationAgent*)agent onPaginationServerError:(NSString*)message;
/**
* Called if connection failed. It may occur due to poor or no internet connectivity
*/
-(void)paginationAgent:(PaginationAgent*)agent onPaginationConnectionError:(NSString*)message;

The php files must return data in json format and must use the format as used:

view plaincopy to clipboardprint?

1. 1,'message'=>'Success','data'=>33);  
2.     echo json_encode($data);  
3.   
4. ?>  

1,'message'=>'Success','data'=>33);
echo json_encode($data);
?>

view plaincopy to clipboardprint?

1. ...  
2. ...  
3. $data = array('success'=>1,'message'=>'Got data','data'=>$rows);  
4.   
5. echo json_encode($data);  

...
...
$data = array('success'=>1,'message'=>'Got data','data'=>$rows);
echo json_encode($data);

See the attached project for details. The php files are inside the folder “PHPFILES”.

1) Integrate iAd 2) ??? 3) PROFIT!

With the iOs SDK 4 now public and the advent of iAds just a few days away, I thought we’d celebrate with a tutorial on how to integrate iAd into your iPhone app!

In this tutorial, not only will we show you how to get started with iAd, but we’ll also show you how to deal with some complex issues you may run into along the way such as:

• Supporting both Portrait and Landscape ads in the same app
• Integrating into a Universal app
• Maintaining backwards compatibility with iOs 3.0
• What to do if you are using a UITableViewController!

We’re actually going to start with where we left off in the How To Port an iPhone Application to the iPad and use the universal app we developed in that tutorial in the starting point.

So grab a copy if you haven’t already, and let’s get to adding some iAds!

Base SDK vs. Deployment Target

The first step to use iAd is to make sure our project has the right Base SDK and iPhone OS Deployment Target selected.

For those of you confused about the difference between the Base SDK and Deployment Target (like I was for quite some time!), here’s what they mean:

• The Base SDK is the version of the SDK you are linking against. Your app can use any classes or functions available in the version of the SDK you choose here – as long as they are available on the actual device the code runs on.
• The Deployment Target is the earliest possible version of the SDK your code can run on. This can be an earlier version than the Base SDK – in fact you often want to set it to be earlier to ensure that as many different versions of the OS can run your code as possible!

The tricky bit is what happens when you want to use a class, function, or framework available in one version of the OS if it’s available, but still work on the old version of the OS if it isn’t. We already did some of this in How To Port an iPhone Application to the iPad, and we’ll do even more in this tutorial!

For this tutorial, we want to set things up so that our code can use stuff available in iOS 4.0 (such as iAd), but still run on as many devices as reasonable (3.0+).

So first let’s set iOs 4.0 as the base SDK. To do this, expand the Targets directory, right click on PortMe, and choose “Get Info”. Click the Build tab, make sure “All Configurations” is selected, navigate to Architectures\Base SDK, and change the value to iPhone Device 4.0.

Then, let’s set iPhone OS 3.0 as the iPhone OS Deployment Target. To do this, still in the Target Build tab, navigate to Deployment\iPhone OS Deployment Target, and change the value to iPhone OS 3.0.

You should now be able to compile and run your app (use the iPhone simulator), and try it out on an iPhone 4 simulator. Once you run your code, in the simulator choose Hardware\Device\iPhone OS 4 and re-run your app. The simulator window will look a little different, and say iPhone 4 in the toolbar, so you’ll know it’s working!

Linking Against the iAd Framework

The next thing we need to do is add the iAd framework to the project. You can do this by right clicking on Frameworks, choosing “Add\Existing Frameworks…”, and choosing “iAd.framework”.

The problem is, if that is all we do our code will break on older devices that don’t have the iAd framework.

You can verify this by trying to run your code in the iPad Simulator 3.2 – boom! The app will crash on startup and you’ll see the following error log:

dyld: Library not loaded: /System/Library/Frameworks/iAd.framework/iAd
Referenced from: /Users/rwenderlich/Library/Application Support/
iPhone Simulator/3.2/Applications/
3ACB1BDA-26F6-43A6-84EA-9FB637B8CDCD/PortMe.app/PortMe
Reason: image not found

To fix this, we need to weak link against the iAd framework. Expand the Targets directory, right click on PortMe, and choose “Get Info”. Click the Build tab, make sure “All Configurations” is selected, and navigate to Linking\Other Linker Flags. Double click on that entry, click the “+” button, and type “-weak_framework iAd”.

Click OK, and then try your app on the iPad simulator again and viola – it should work!

Preparing our XIB

In this tutorial, we’re going to integrate iAd into both the PortMeGameListController and the PortMeGameDetailsController. However, the integration is a bit easier in the PortMeGameDetailsController because it is a subclass of UIViewController, so we’re going to start there first.

Open up PortMeGameDetailsController.xib. You’ll see that all of the controls are children of a single view:

What we’re going to need to do with iAd is scroll an ad view onto the screen when an ad is available, and shrink the rest of the content to fill the remaining space. As currently designed, this isn’t that easy because all of the controls are direct children of the root view. But there’s an easy way to fix it – we’ll simply move the controls into a subview instead!

The easiest way to do this is to drag another view from the library into the XIB, and change its size to be the same as the existing view’s size (320×416). Then drag the existing view as a subview of the new view. When you’re done, it should look like the following:

Then, control-drag from the File’s Owner to the new view (which is now the root view) to connect it to the view outlet. Save your XIB, and run the project and verify that everything still works OK with the details view (in particularly that orientation resizing works correctly). If all works well, we’re one step closer to integrating iAd!

Simple iAd Integration

Ok, now let’s get to the fun part – integrating iAd!

First, make the following changes to PortMeGameDetailsController:

// In the import section #import "iAd/ADBannerView.h"   // Modify the PortMeGameDetailsController interface @interface PortMeGameDetailsController : UIViewController <GameSelectionDelegate, UISplitViewControllerDelegate, ADBannerViewDelegate> {   // Inside the PortMeGameDetailsController interface UIView *_contentView; id _adBannerView; BOOL _adBannerViewIsVisible;   // After the interface @property (nonatomic, retain) IBOutlet UIView *contentView; @property (nonatomic, retain) id adBannerView; @property (nonatomic) BOOL adBannerViewIsVisible;

We first include the iAd headers and mark the view controller as implementing the ADBannerViewDelegate. This way, we can receive events as ads become available or not.

We then declare a property to keep track of the content view that contains all of the controls (basically the inner UIView). We also declare a variable to keep track of our iAd banner view, and whether or not it’s currently visible.

Note that we declare the iAd banner view as an id variable rather than as a ADBannerView. This is because we want to ensure backwards compatibility all the way to OS 3.0, and the ADBannerView class is only available on 4.0+, so we need to weak link against it.

Before we forget, let’s hook up our content view to the new outlet we just made. Make sure you save PortMeGameDetailsController.h, go back to PortMeGameDetailsController.xib, control-drag from the File’s Owner to the inner (second) UIView, and connect it to the contentView outlet.

Then switch over to PortMeGameDetailsController.m and make the following changes:

// In the synthesize section @synthesize contentView = _contentView; @synthesize adBannerView = _adBannerView; @synthesize adBannerViewIsVisible = _adBannerViewIsVisible;   // In the dealloc section self.contentView = nil; self.adBannerView = nil;

Next, we’re going to add the meat of the code. But there’s a lot of it – so let’s break it down into 6 steps.

1) Add helper functions to get height of iAd banner

- (int)getBannerHeight:(UIDeviceOrientation)orientation { if (UIInterfaceOrientationIsLandscape(orientation)) { return 32; } else { return 50; } }   - (int)getBannerHeight { return [self getBannerHeight:[UIDevice currentDevice].orientation]; }

There are several places in the rest of the code where we’re going to want to know how large the banner view should be given a particular orientation. Currently iAds have two possible sizes: 320×50 for landscape, or 480×32 for portrait. So we simply retrieve the proper height based on the passed in orientation.

2) Add helper function to create the iAd view

- (void)createAdBannerView { Class classAdBannerView = NSClassFromString(@"ADBannerView"); if (classAdBannerView != nil) { self.adBannerView = [[[classAdBannerView alloc] initWithFrame:CGRectZero] autorelease]; [_adBannerView setRequiredContentSizeIdentifiers:[NSSet setWithObjects: ADBannerContentSizeIdentifier320x50, ADBannerContentSizeIdentifier480x32, nil]]; if (UIInterfaceOrientationIsLandscape([UIDevice currentDevice].orientation)) { [_adBannerView setCurrentContentSizeIdentifier: ADBannerContentSizeIdentifier480x32]; } else { [_adBannerView setCurrentContentSizeIdentifier: ADBannerContentSizeIdentifier320x50]; } [_adBannerView setFrame:CGRectOffset([_adBannerView frame], 0, -[self getBannerHeight])]; [_adBannerView setDelegate:self];   [self.view addSubview:_adBannerView]; } }

This helper function creates an ADBannerView in a manner that is safe to use across multiple OS versions. It uses weak linking and NSClassFromString to check if the ADBannerView class is available – if it is not, the method will return nil and the function will bail.

However, if it is available it creates an instance of the class. It then uses the setRequiredContentSizeIdentifiers to specify what kind of ads this app needs. For our case, our app supports both portrait and landscape modes so it needs both ad options.

It then calls setCurrentContentSizeIdentifier to tell iAd which ad it should display. We simply choose the correct one by looking at the current orientation.

Next, we need to set the frame for the iAd. Note there’s some funky business here – we actually set the frame of the view to be offscreen! This is because we don’t know if an ad is available yet, and we don’t want to display the view until we know one is.

We set our view controller as the delegate so that we can receive notice about iAds being available or not. Then finally we ad the new iAd banner view as a subview of our view!

Note something subtle about the above – we always use message passing syntax rather than dot notation (i.e. [_adBannerView setRequiredContentSizeIdentifiers:...] instead of _adBannerView.requiredContentSizeIdentifiers = …). This is again to make sure everything runs fine on OS 3.0+.

3) Add function to size views correctly

- (void)fixupAdView:(UIInterfaceOrientation)toInterfaceOrientation { if (_adBannerView != nil) { if (UIInterfaceOrientationIsLandscape(toInterfaceOrientation)) { [_adBannerView setCurrentContentSizeIdentifier: ADBannerContentSizeIdentifier480x32]; } else { [_adBannerView setCurrentContentSizeIdentifier: ADBannerContentSizeIdentifier320x50]; } [UIView beginAnimations:@"fixupViews" context:nil]; if (_adBannerViewIsVisible) { CGRect adBannerViewFrame = [_adBannerView frame]; adBannerViewFrame.origin.x = 0; adBannerViewFrame.origin.y = 0; [_adBannerView setFrame:adBannerViewFrame]; CGRect contentViewFrame = _contentView.frame; contentViewFrame.origin.y = [self getBannerHeight:toInterfaceOrientation]; contentViewFrame.size.height = self.view.frame.size.height - [self getBannerHeight:toInterfaceOrientation]; _contentView.frame = contentViewFrame; } else { CGRect adBannerViewFrame = [_adBannerView frame]; adBannerViewFrame.origin.x = 0; adBannerViewFrame.origin.y = -[self getBannerHeight:toInterfaceOrientation]; [_adBannerView setFrame:adBannerViewFrame]; CGRect contentViewFrame = _contentView.frame; contentViewFrame.origin.y = 0; contentViewFrame.size.height = self.view.frame.size.height; _contentView.frame = contentViewFrame; } [UIView commitAnimations]; } }

This is a helper function we can call to make sure our views are in the right position. If ads are available, we want the ad banner view to be at the top of the screen and the content view shrunk a bit to fill the rest of the area. If ads are not available, we want the ad banner view offscreen and the content view as large as the entire view here.

And that’s exactly what the above function does. It looks long, but is fairly simple and self-explanatory. Note that we wrap the resizing code in an animation block to make things look awesome.

4) Call createAdView in viewDidLoad

- (void)viewDidLoad { [self createAdBannerView]; }

We want to create our ad view as soon as our view is loaded, even if we aren’t ready to display it quite yet.

5) Call fixupAdView in viewWillAppear and willRotateToInterfaceOrientation

- (void) viewWillAppear:(BOOL)animated { [self refresh]; [self fixupAdView:[UIDevice currentDevice].orientation]; }   - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [self fixupAdView:toInterfaceOrientation]; }

We need to fix up our ad view in viewWillAppear, because the device may have changed orientations in the time between when our view was visible last and now. And we obviously need to change it upon rotation as well!

6) Implement ADBannerViewDelegate

#pragma mark ADBannerViewDelegate   - (void)bannerViewDidLoadAd:(ADBannerView *)banner { if (!_adBannerViewIsVisible) { _adBannerViewIsVisible = YES; [self fixupAdView:[UIDevice currentDevice].orientation]; } }   - (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error { if (_adBannerViewIsVisible) { _adBannerViewIsVisible = NO; [self fixupAdView:[UIDevice currentDevice].orientation]; } }

Now that we have our helper functions, implementing the ADBannerViewDelegate methods are quite simple. We simply toggle whether the ad banner view should be visible or not, and call fixupAdView.

Done!

And that’s it! Compile and run your project, and you should see ads appear correctly in both portrait and landscape mode.

And best yet – if you run the code on an iPad or iPhone 3.0 device it will work just fine as well, but without ads!

UITableView integration

Well that worked great for our details controller, but we want it in our list controller too!

The problem is our list controller is a UITableViewController. Unfortunately, it seems like the best way to deal with this situation is to convert your UITableViewController to a normal UIViewController and then proceed similarly to the way we did above. So here are all of the gory steps:

1) Create a XIB for PortMeGameListController

Go to File\New File, choose User Interface and View XIB, make sure Product is iPhone, and click Next. Name the XIB PortMeGameListController.xib and click Finish.

Open up the XIB, click on the File’s Owner, and in the fourth tab of the Attributes Inspector change the class to PortMeGameListController.

Then drag a UIView into the current UIView (so there are 2, just like we did before), and add a UITableView to the inner view. When you’re done it should look like this:

2) Make some changes to PortMeGameListController

Inside PortMeGameListController.h:

// Change the interface declaration @interface PortMeGameListController : UIViewController <UITableViewDelegate, UITableViewDataSource> {   // Add inside class UITableView *_tableView; UIView *_contentView;   // Add after class @property (nonatomic, retain) IBOutlet UITableView *tableView; @property (nonatomic, retain) IBOutlet UIView *contentView;

Inside PortMeGameListController.m:

// In synthesize section @synthesize tableView = _tableView; @synthesize contentView = _contentView;   // In dealloc section self.tableView = nil; self.contentView = nil;

Don’t forget to save the files!

3) Hook up outlets

Now go back to PortMeGameListController.xib and connect the first view to the view outlet, the second to the contentView outlet, and the third to the tableView outlet.

Also control-drag from the tableView back to the File’s Owner and set it as the delegate and datasource.

4) Set the NIB name for PortMeGameListController in MainWindow

Open MainWindow.xib and MainWindow-iPad.xib, expand the Navigation Controller, select “Port Me Game List Controller”, and change the nib name to PortMeGameListController.

5) Compile and test to make sure everything works as usual

At this point, compile and run your code and make sure everything works as it usually does – but now you’re using a UIViewController rather than a TableViewController, and you have a XIB laid out in a nice way to use iAds!

6) Follow the steps from the previous section

Now you’re exactly where we were in the previous section with a view controller – so follow the same steps to integrate in this view!

Done!

If all goes well, you should be able to compile and run your project and see advertisements at the top of your table view!

Where To Go Now?

Here is a sample project with all of the code we’ve developed in the above tutorial.

Now you should know how to integrate iAds into your projects – no matter what OSs you wish to support for your app! I’d love to hear your experiences with iAds and how well they are working (or not) for your app!
