add notification method 

[[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(moviepreloaddidfinish:) name:mpmovieplayerloadstatedidchangenotification                                                object:player];

this method called after movie loaded , in method add movieplayer view.

-(void)moviepreloaddidfinish:(nsnotification*)notification {     movieplayer.controlstyle=mpmoviecontrolstyledefault;    [self.view addsubview:movieplayer.view];    [movieplayer play];    [movieplayer setfullscreen:yes animated:yes];  }
