How to get notified when the status bar height changes?

Question

Does the OS send notifications when the status bar height changes? For example that fat in-call status bar?

Answer 1

Yes. Your app delegate can implement these methods:

• -application:willChangeStatusBarFrame:
• -application:didChangeStatusBarFrame:

and these local notifications will also be sent to the default notification center:

• UIApplicationWillChangeStatusBarFrameNotification
• UIApplicationDidChangeStatusBarFrameNotification
