applicationWillTerminate不被调用

本文介绍了applicationWillTerminate不被调用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想在终止之前保存数据，所以我的AppControll类符合NSApplicationDelegate协议，并声明了该方法；在接口构建器中，我将窗口的委托出口绑定到AppController，但无法调用该方法.

I want to save my data before terminating, so my AppControll class conforms the NSApplicationDelegate protocol, and declared the method; and in the interface builder I bound the window's delegate outlet to AppController, but I cannot get the method invoked.

如果我错了，该怎么办?

Where I am wrong, what should I do?

推荐答案

您还记得将处理程序添加到应用程序吗?

Did you remember to add the handler to the application?

UIApplication *app = [UIApplication sharedApplication];
[[NSNotificationCenter defaultCenter]
   addObserver:self
   selector:@selector(applicationWillTerminate:)
   name:UIApplicationWillTerminateNotification object:app];
