dyld: Symbol not found: _MPMoviePlayerPlaybackStateDidChangeNotification

I am building universal app which uses MPMoviePlayerViewController to play the video. Observing notification "MPMoviePlayerPlaybackStateDidChangeNotification". The app successfully runs in iPad simulator but throws following error when it runs in iPhone:-

Is any one having the same issue and got resolved?
