为UIToolBar工具条添加各�U�各��L(f��ng)��UIBbarButtonItem(转蝲)

��剑��秋 — Tue, 16 Aug 2011 02:09:00 GMT

(转蝲请保留此文字�Q�本文来�?[iphone开发私房菜_2_] 为UIToolBar工具条添加各�U�各��L(f��ng)��UIBbarButtonItem http://blog.csdn.net/ipromiseu/archive/2010/12/16/6080689.aspx] write by Gray.Luo guohui.great@gmail.com)

1.首先�Q�我们看一下UIBbarButtonItem有哪些初始化�Ҏ(gu��)��Q�这也可以看出，它可以被定义��Z��么东东，然后加到UIToolBar上面厅R�?/p>

�Ҏ(gu��)��SDK的文档，我们可以发现UIBbarButtonItem有如下几�U�初始化的方法：(x��)

-initWithTitle

-initWithImage

-initWithBarButtonSystemItem

-initWithCustomView

�W?�U�方法就是我们添加各�U�作料的接口�Q�所以今天的主角其它也是它�?/p>

2.在UIToolBar上面��d��Title

view plain

UIToolbar *myToolBar = [[UIToolbar alloc] initWithFrame:
CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
NSMutableArray *myToolBarItems = [NSMutableArray array];
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
initWithTitle:@"myTile"
style:UIBarButtonItemStylePlain
target:self
action:@selector(action)] autorelease]];
[myToolBar setItems:myToolBarItems animated:YES];
[myToolBar release];
[myToolBarItems];

setItems传入值或者说items是一个对象数�l��?/p>

3.在UIToolBar上面��d��image

view plain

[myToolBarItems addObject:[[[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:@"myImage.png"]
style:UIBarButtonItemStylePlain
target:self
action:@selector(action)]];

4.在UIToolBar上面��d��SystemItem

view plain

[myToolBarItems addObject:[[[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemPlay
target:self
action:@selector(action)] autorelease]];

Note:

initWithBarButtonSystemItem初始化：(x��)

- (id)initWithBarButtonSystemItem:(UIBarButtonSystemItem)systemItem target:(id)target action:(SEL)action

Defines system defaults for commonly used items.

view plain

typedef enum {
UIBarButtonSystemItemDone,
UIBarButtonSystemItemCancel,
UIBarButtonSystemItemEdit,
UIBarButtonSystemItemSave,
UIBarButtonSystemItemAdd,
UIBarButtonSystemItemFlexibleSpace,
UIBarButtonSystemItemFixedSpace,
UIBarButtonSystemItemCompose,
UIBarButtonSystemItemReply,
UIBarButtonSystemItemAction,
UIBarButtonSystemItemOrganize,
UIBarButtonSystemItemBookmarks,
UIBarButtonSystemItemSearch,
UIBarButtonSystemItemRefresh,
UIBarButtonSystemItemStop,
UIBarButtonSystemItemCamera,
UIBarButtonSystemItemTrash,
UIBarButtonSystemItemPlay,
UIBarButtonSystemItemPause,
UIBarButtonSystemItemRewind,
UIBarButtonSystemItemFastForward,
UIBarButtonSystemItemUndo, // iPhoneOS 3.0
UIBarButtonSystemItemRedo, // iPhoneOS 3.0
} UIBarButtonSystemItem;

5.在UIToolBar上面��d��其它各种控�g,最自由意义�Q�最有意思的�Q�我把它攑֜�最后来讌Ӏ�我们��用initWithCustomView来完成，

�q�里需要看一下initWithCustomView的定义：(x��)

- (id)initWithCustomView:(UIView *)customView

可以看出�Q�它的参数是一个VIEW�Q�所以我们给它的配料要正��哦才行哦，否则�Q�你��q��着旉��DIDADIDA的流失吧.

A>加一个开关switch�Q?/p>

view plain

[myToolBarItems addObject:[[[UIBarButtonItem alloc]
initWithCustomView:[[[UISwitch alloc] init] autorelease]]
autorelease]];

B>加一个按钮UIBarButtonItem

view plain

UIBarButtonItem *myButton = [[[UIBarButtonItem alloc]
initWithTitle:@"myButton"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(action)]autorelease];
get1Button.width = 50;
[myToolBarItems addObject:myButton];

C>加一个文本Label

view plain

UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(40.0f, 20.0f, 45.0f, 10.0f)];
myLabel.font=[UIFont systemFontOfSize:10];
//myLabel.backgroundColor = [UIColor clearColor];
//myLabel.textAlignment=UITextAlignmentCenter;
UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myLabel];
[myToolBarItems addObject: myButtonItem];
[mylabel release];
[myButtonItem release];

D>加一个进度条UIProgressView

view plain

UIProgressView *myProgress = [[UIProgressView alloc] initWithFrame:CGRectMake(65.0f, 20.0f, 90.0f, 10.0f)];
UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myProgress];
[myToolBarItems addObject: myButtonItem];
[myProgress release];
[myButtonItem release];

可以加��用initWithCustomView制作各种button�Q�这里就不在�q�里一个一个在加了(ji��n)。我想你应该也已�l�掌握了(ji��n)如何��d��各种buttonItem的方法了(ji��n)�?/p>

iphone开发的一些小技�?一)(关键字：(x��)除去UITableView的边框和划动删除�Q�同步请求及(qi��ng)异步��h��)

��剑��秋 — Thu, 11 Aug 2011 05:48:00 GMT

1. 如何除去UITableViewStyleGroup�c�d��的UITableView的边框：(x��)

UITableViewStylePlain�c�d��的UITableView去除�Ҏ(gu��)��U�有直接的属性方法：(x��)

separatorStyle = UITableViewCellSeparatorStyleNone;

但在UITableViewStyleGrouped�c�d��的UITableView中，该方法无�?br />

如何去除�Ҏ(gu��)��U�呢�Q�答案很��单：(x��)

separatorColor=[UIColor clearColor];

2. UITableView划动删除的实�?/strong>

需要实��C��面两个方�?/p>

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {

return YES;

}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath: (NSIndexPath *)indexPath {

if (editingStyle == UITableViewCellEditingStyleDelete) {

[dataArray removeObjectAtIndex:indexPath.row];

// Delete the row from the data source. [testTableView deleteRowsAtIndexPaths: [NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

}else if (editingStyle == UITableViewCellEditingStyleInsert) { // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.

}

3. NSURLConnection同步�Q�异步与SSL  
    同步��h��
        NSURL *url=[[NSURL alloc]initWithString:urlString];
	NSMutableURLRequest  *request=[[NSMutableURLRequest alloc]init];
	NSError *err=nil;
 	NSData *data=[NSURLConnection sendSynchronousRequest:request
									   returningResponse:nil 
												   error:&err];
	if(data==nil)
	{
		//if([err code])
		
		NSLog(@"Code:%d,domain:%@,localizedDesc:%@",[err code],
			  [err domain],[err localizedDescription]);
	}
	else
	{
	}
      �q�种情况�Q�通过一个静(r��n)态方法，��h��request,�q�种情况下，�?x��)一直阻塞，�{�到�q�回�l�果�Q�简单易�?br />        异步��h��
	NSURL *url=[[NSURL alloc]initWithString:urlString];
	NSMutableURLRequest  *request=[[NSMutableURLRequest alloc]init];
	NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
	[url release];
	[request release];
	if(connection)
	{
        	receivedData = [[NSMutableData data] retain];
        	NSLog(@"intial done!");
    	}
	else
	{
        	NSLog(@"sorry");
    	}
        通过一个delegate来做数据的下载以�?qi��ng)Request的接受等�{�消息，此处delegate:self�Q�所以需要本�c�d����C��些方法，�q�且定义receivedData做数据的接受
        基本上要实现下面节歌�Ҏ(gu��)��
	- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 
	{
		NSLog(@"get the whole response");
    		[receivedData setLength:0];
	}
	- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
	 {
		NSLog(@"get some data");
    	[receivedData appendData:data];
	}
	- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
	{
		[connection release];
	}
	-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
	{
    		[connection release];
   	 	NSLog(@"Connection failed! Error - %@ %@",	  
          	[error localizedDescription],		  
         	 [[error userInfo] objectForKey:NSErrorFailingURLStringKey]);
	}
    基本上这样就搞定�?ji��n)！�Q�！
    但是异步模式下带来了(ji��n)一个新的问题，很多情况下，�|�络��h��不在�ȝ���E�，或者界面等待网�l�结果，不在�ȝ���E�的时候，调用�U�程如果生命周期o(w��)ver�Q�下面这些可能都没有调用刎ͼ���D��得不到想要得效果�Q�所以需要在NSURLConnection��h��后面加点东西来阻�?br />    while(!finished) {
	[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
	}	

    好了(ji��n)�Q�现在我们看看SSL的问题，在NSURLConnnection本来有方法可以蟩�q�ssl���(g��)查，可惜被apple无情的私有了(ji��n)�Q�所以同步的数据��h��肯定不行�?ji��n)，看看文档�Q�只能通过异步delegate的方式了(ji��n)
    - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace 
    {
	return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
    }
    - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge 
    {
	if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
	if ([trustedHosts containsObject:challenge.protectionSpace.host])
		[challenge.sender useCredential:[NSURLCredential	credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
	[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
    }
    �W�一个方法会(x��)�Ҏ(gu��)��你的URL来判断是否需要做认证
    �W�二个方法是认证的过�E�，if ([trustedHosts containsObject:challenge.protectionSpace.host])�Q�这行代码注释掉�Q�就可以自动所有SSL通过�Q�否则，你可以加一些Trust的hosts�Q�其他的不通过���p���?ji��n)！�Q�！

NSRang是一个结构体�Q�有两个属性：(x��)location和length

location:是一个烦(ch��)引，该烦(ch��)引标识的是在�Q�字�W�串中捡索到�Q�字�W�串的烦(ch��)引；

length:�?/span>捡烦(ch��)的字�W�串的长度，卻I��字符串的长度�Q?/span>

下面是随手写的一个简单的例子�Q?/span>

   NSString *ns = @"aabbcc?eeff";

NSRange rng = [ns rangeOfString:@"?"];

NSInteger lo = rng.location;

NSString *ts = [ns substringToIndex:lo];

NSLog(@"substringToIndex: %@",ts);

NSString *fs = [ns substringFromIndex:(lo+1)];

NSLog(@"substringFromIndex: %@",fs);

打印的结果：(x��)2011-08-08 15:48:36.068 wCityFW[2375:207] substringToIndex: aabbcc

   2011-08-08 15:48:36.069 wCityFW[2375:207] substringFromIndex: eeff

由此我们可以看出substringToIndex�Q�是从将要检索的字符�Ԍ��卻I��字符串的首字�W�到��(g��)索到�Q�字�W�串的烦(ch��)引的一�D�子字符�Ԍ��

     substringFromIndex�Q�是从检索到�Q�字�W�串的烦(ch��)引到被检索的字符串末字符的一�D�字�W�串�?/strong>
