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
