I need to implement event when i close my app in iOS like following pic.

I want to catch that event when i close app with that minus button.

Which event i need to do?

解决方案

This delegete will be called when your application is going to terminate.

- (void)applicationWillTerminate:(UIApplication *)app
{
}

If you are using iOS 4 or greater and with multi-tasking support, applicationWillTerminate will not be called.

For receiving the terminate event you need to add UIApplicationExitsOnSuspend key on your info.plist
