Question

My controller main view call

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:YES];

in it’s viewDidAppearmethod because the screen must be manually rotated for the user.

Everything works perfectly except when I put the app in background and I re-enter foreground on this screen: Then the navigationBar’s height become 32px.

If I comment the setStatusBarOrientation call, then no problem.

I’ve logged the navigationBar height in didEnterForeground method (after the super call), but it tells 44px. So I guess it would be resized after.

So I would like to know :

• If there was a way to prevent the navigationBar to be resized
• If no, what other callback method would come after the didEnterForeground one (viewWill/DidAppear does’nt)

Thanks !

After 4 months, I finally found a partial solution !

• If no, what other callback method would come after the didEnterForeground one (viewWill/DidAppear does’nt)

I found a good callback when a viewController (not app delegate) is re-entering foreground. With NSnotificationCenter

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

don’t forget to remove

[[NSNotificationCenter defaultCenter] removeObserver:self name:UIApplicationWillEnterForegroundNotification object:nil];
