推荐答案

您的应用程序可以选择退出多任务处理(请参阅 UIApplicationExitsOnSuspend 键到 Info.plist 并将其值设置为 YES.

Your application can opt out of multitasking (see the appropriate section in the iPhone Application Programming Guide) by adding the UIApplicationExitsOnSuspend key to your Info.plist and setting its value to YES.

实际上，Apple 强烈建议您不要这样做，除非您有充分的理由这样做.

In practice, Apple strongly recommends you not do this unless you have a very good reason for this behavior.
