- (void)applicationWillResignActive:(UIApplication *)application

Along with the applicationDidBecomeActive: and applicationWillEnterForeground: messages sent to the application delegate, the OS will also send corresponding UIApplicationDidBecomeActiveNotification and UIApplicationWillEnterForegroundNotification notifications.

You can have your view controller listen to these notifications:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(appWillEnterForegroundNotification:) 
                                             name:UIApplicationWillEnterForegroundNotification 
                                           object:nil];

Don't forget to remove yourself as an observer before your view controller gets destroyed.

– applicationDidBecomeActive:
– applicationWillEnterForeground:

Oops didnt read your question properly. These two methods are in the UIApplicationDelegate

– viewWillAppear:
– viewDidAppear:

And those are in UIViewController
