I have an application of which i have created .ipa file and tried to run the application on iOS5. 
我有一个已创建.ipa文件并尝试在iOS5上运行该应用程序的应用程序。 If i run it on iOS 5, it works but when i try to run it on iOS4.2 it doesn't work. 如果我在iOS 5上运行它，则可以运行，但是当我尝试在iOS4.2上运行它时，则无法运行。 It opens up, shows black window and then back to home screen. 它打开，显示黑色窗口，然后返回主屏幕。 I have tried things like deleting app, installing again, restarting phone, reseting it's setting. 我尝试过删除应用程序，重新安装，重新启动手机，重置其设置等操作。

Your only hope is the console, see what it says about why it is dying. 您唯一的希望是控制台，看看它说了什么会死的。 If that doesn't give any messages, stop it in the debugger in AplicationDidFinishLaunching, and step as far as you can... 如果那没有给出任何消息，请在AplicationDidFinishLaunching中的调试器中将其停止，并尽可能地扩展...
The console though SHOULD have a message about why the app is terminating early. 控制台应该有关于应用程序为何提前终止的消息。 Without knowing why, we cannot help further. 不知道为什么，我们无法进一步提供帮助。

Did you change your build target immediately before creating the .ipa? 在创建.ipa之前，您是否立即更改了构建目标？ If so, do a clean build and then re-create the .ipa file again—that may fix your problem. 如果是这样，请执行干净的构建，然后再次重新创建.ipa文件，这可能会解决您的问题。
