我想取消该方法,当用户按下“HOME”按钮时请求用户确认,在 iPhone 上,该按钮将进入后台执行。

如果用户接受,则进入后台执行,如果不接受,我不做任何事情。

我查看了论坛、Apple 的文档,但什么也没找到。

有人可以帮助我吗?

提前致谢!

最佳答案

不,你不能覆盖它。该事件始终会触发,但它确实给您时间在移动到后台之前进行清理。

Your delegate’s applicationDidEnterBackground: method has approximately five seconds to finish any tasks and return. In practice, this method should return as quickly as possible. If the method does not return before time runs out, your application is terminated and purged from memory. If you still need more time to perform tasks, call the beginBackgroundTaskWithExpirationHandler: method to request background execution time and then start any long-running tasks in a secondary thread. Regardless of whether you start any background tasks, the applicationDidEnterBackground: method must still exit within five seconds
