1 Launch Keychain Access from your local Mac and from the login keychain, filter by the Certificates category. You will see an expandable option called “Apple Development Push Services”

2 Right click on “Apple Development Push Services” > Export “Apple Development Push Services ID123″. Save this as apns-dev-cert.p12 file somewhere you can access it. There is no need to enter a password.

3 The next command generates the cert in Mac’s Terminal for PEM format (Privacy Enhanced Mail Security Certificate):

openssl pkcs12 -in apns-dev-cert.p12 -out apns-dev-cert.pem -nodes -clcerts

 atos -o AppName.app.dSYM/Contents/Resources/DWARF/AppName  -arch armv7 0x0000b82

這樣就能看到，地址對應(yīng)的類，函數(shù)，代碼行數(shù)。這個(gè)命令只能解析出客戶代碼的位置。若是錯(cuò)誤堆棧中的系統(tǒng)調(diào)用，是無法翻譯出來的。
