Detect touch action that involves status bar

Question

I have to perform action when user returns from expanded status bar. What I can do: 1. User touches status bar. using this code

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(onStop)
                                                 name:UIApplicationWillResignActiveNotification
                                               object:nil];

How to detect this action: 2. Returning from status bar? This method doesn't work

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

Any solution?

Use UIApplicationDidBecomeActiveNotification

instead of

UIApplicationWillEnterForegroundNotification .
