How to detect when iPhone MPMoviePlayer controls appear/disappear?

Question

I'm trying to add custom buttons to the left and right of the standard rewind/play/forward controls in an MPMoviePlayerController view (OS 2.x and up). I've figured out how to add them to the player window, but they're always visible. Is there a way to detect when the standard controls appear and disappear?

Answer 1

Look into the movieControlMode property. You can set the MPMovieControlMode

MPMovieControlMode Options for displaying movie playback controls.

typedef enum {
   MPMovieControlModeDefault,
   MPMovieControlModeVolumeOnly,
   MPMovieControlModeHidden
} 

MPMovieControlMode;

You can also check out MPMoviePlayerScalingModeDidChangeNotification

Answer 2

Mark, did you ever figure this out? I'm looking for the same sort of notification...

Thanks in advance!

Answer 3

I am also looking for a way to determine whether the controls in the MPMoviePlayerController appear or disappear?

Any other suggestions on how to implement this?

pre iOS3.2
to detect "disapierance" is easy:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerController];

to detect appierance is bit harder (maybe there is better way):

...
[moviePlayerController play];
mainTimer = [NSTimer scheduledTimerWithTimeInterval:1/100 target:self selector:@selector(tick) userInfo:nil repeats:YES];

- (void)tick {
  if( [[[UIApplication sharedApplication] windows] count] < 2 ) return;

  moviePlayerWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
  if( moviePlayerWindow ){
    [mainTimer invalidate], mainTimer=nil;
    // here you have moviePlayerWindow
  }
}
