问题描述

我的AppDelegate的applicationWillTerminate:方法中有一些代码，但是我不知道如何测试它是否有效.使用Xcode停止模拟器不会触发它.

I have some code in my AppDelegate’s applicationWillTerminate: method but I don’t know how to test if it works. Using Xcode to stop the simulator does not trigger it.

如何在applicationWillTerminate中测试代码??

推荐答案

模拟器不会发送applicationWillTerminate:，因为跳板没有向您发送终止代码(SIGABRT)，而LLDB则向您发送.要触发这些委托方法，您必须使用Home Button命令(⌘+⇧+ H)，然后拉起多任务抽屉并从此处杀死您的应用程序.您的调试会话将立即终止，并且委托方法将成功触发.

The simulator doesn't send applicationWillTerminate: because the springboard isn't sending you the kill code (SIGABRT), LLDB is. To trigger those delegate methods, you have to use the Home Button command (⌘+⇧+H), then pull up the multitasking drawer and kill your application from there. Your debugging session will immediately terminate, and the delegate method will fire successfully.
