如果您想支持多任务处理，则应该在应用程序委托中以及
- ( void)applicationWillTerminate:(UIApplication *)application以支持不支持多任务或 4.0 之前的 iOS 的设备。但您也可以强制 iOS 使用“旧”行为，即不支持多任务并始终调用
applicationWillTerminate:。为此，您需要编辑 Info.plist 并添加带有布尔值 YES 的UIApplicationExitsOnSuspend键。If you want to support multi-tasking you are supposed to implement the
- (void)applicationDidEnterBackground:(UIApplication *)applicationmethod in your app delegate for saving state, as well as in- (void)applicationWillTerminate:(UIApplication *)applicationto support devices that do not have multi-tasking support or pre 4.0 iOS.But you can also force iOS to use the "old" behavior, that is to not support multi-tasking and always call
applicationWillTerminate:. To do that, you need to edit your Info.plist and add the keyUIApplicationExitsOnSuspendwith a boolean value YES.
