问题描述

在 iOS 4 中，当用户按下 Home 按钮时，正在运行的应用程序将保存当前状态并进入后台.但是我正在开发一个应用程序，我不希望它进入后台.我希望它自杀，就像在 iOS 3 及之前的版本中一样.我该怎么做?谢谢.

In iOS 4, when a user presses the Home button, the running app will save the current state and go to background. However I'm developing an app and I don't want it to go to the background. I want it to kill itself, just like in iOS 3 and before. How can I do it? Thanks.

See "Opting Out of Background Execution" in the iOS Application Programming Guide:

"...您可以明确选择退出通过添加后台执行模型UIApplicationExitsOnSuspend 键您的应用程序的 Info.plist 文件和将其值设置为 YES."
