iOS Using MPMoviePlayerViewController in Fullscreen (iPad)

I have a single view app with 5 buttons and when one of the buttons is pressed, the player slides up over the original view and begins playing the video in fullscreen (as it should).

All works great with the exception of when pressing the Fullscreen/Minimize icon (the two diagonal arrows pointing to each other next to the play back controls). When pressing this, the original view with the five buttons slides up over the video player. The problem is the video is still playing underneath the original view. I would really like to eliminate the Fullscreen/Minimize icon but from I can tell, that does not seem possible. So... I am thinking, I might be able to use an observer to listen to when the Fullscreen/Minimize icon is pressed and I can do what I need to. I just can not find anything solid on how to do this. Any help/direction would be greatly appreciated.

Here is my current code...

-(IBAction)playvideo {

 NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Megamind" ofType:@"mov"]];
 MPMoviePlayerViewController * playerController = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

 [self presentMoviePlayerViewControllerAnimated:(MPMoviePlayerViewController *)playerController];

 playerController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
 [playerController.moviePlayer play];
 [playerController release];
 playerController=nil;
}

- (void)moviePlayerWillExitFullscreen:(NSNotification *)theNotification {

 MPMoviePlayerController *playerController = [theNotification object];
 [[NSNotificationCenter defaultCenter] addObserver:self
            selector:@selector(moviePlayerWillExitFullscreen:)
             name:MPMoviePlayerWillExitFullscreenNotification
              object:nil];

 [playerController stop];

}

This line is causing you that behaviour.

[self presentMoviePlayerViewControllerAnimated:(MPMoviePlayerViewController *)playerController];

It is pretty much similar to your regular presentModalViewController method.

It presents the Movieplayer and its view controller Modally. So the default settings here are

movieplayer.controlStyle = MPMovieControlStyleFullScreen

which are set up by default.

So when you press those diagonal arrows, it exits that mode, and gives a notification for that. But you have to setup an observer first to listen to that notifcation as you did for movie finished.

You did

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedPlayback:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

This adds a notification to observe for movie completion notifications. For exiting full screen mode add one more observer that is this..

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieExitFullScreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];

And you should be good to go after adding the -(void) movieExitFullScreen:(NSNotification *) selector for the same. Hope it helps. :)

Put this line just after the init of your MPMoviePlayer :

[[NSNotificationCenter defaultCenter] addObserver:self
            selector:@selector(moviePlayerWillExitFullscreen:)
             name:MPMoviePlayerWillExitFullscreenNotification
              object:nil];

I think you're adding the observer in the method where you want to be REMOVING it.

You want this

MPMoviePlayerController *playerController = [theNotification object]; 
[[NSNotificationCenter defaultCenter] addObserver:self
        selector:@selector(moviePlayerWillExitFullscreen:)
         name:MPMoviePlayerWillExitFullscreenNotification
          object:nil];

in the playVideo()

and THIS

[[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:name:MPMoviePlayerWillExitFullscreenNotificationn
                                                  object:nil];

in the moviePlayerWillExitFullscreen method.

I did find a solution and my lack of knowledge put me in a situation where I do not fully understand why it works this way. My apologies for not having a thorough reasoning. In my original code... the MPMoviePlayerWillExitFullscreenNotification was not answering to taps. This is true for MPMoviePlayerDidExitFullscreenNotification as well. What was answering was MPMoviePlayerPlaybackDidFinishNotification. Here is teh working code in knowing that the MPMoviePlayerPlaybackDidFinishNotification was working and also applied to the Fullscreen/Embed presses.

-(IBAction)playvideo {

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Megamind" ofType:@"mov"]];
MPMoviePlayerViewController * playerController = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedPlayback:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

[self presentMoviePlayerViewControllerAnimated:(MPMoviePlayerViewController *)playerController];

playerController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[playerController.moviePlayer play];
[playerController release];
playerController=nil;
NSLog(@"playvideo");
}

- (void)movieFinishedPlayback:(NSNotification*)notification {

            MPMoviePlayerController *playerController = [notification object];
            [playerController pause];
            [self dismissMoviePlayerViewControllerAnimated];

}
