Playing a video in iOS app: audio but no picture - iphone

Question

i want a short video to play in my iphone app. When i use the code below, i only hear the audio and see
the regular view of the app. I want the video to play on top of this view.
What can i do about this?
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"LEADER" ofType:#"mov"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.scalingMode = MPMovieScalingModeAspectFill;
[theMovie play];
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];

Answer 1

Don't mix up MPMoviePlayerController and MPMoviePlayerViewController. When you use MPMoviePlayerController use it like this (typically for embedded videos on the iPad):
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: myURL];
[player.view setFrame: myView.bounds]; // player's frame must match parent's
[myView addSubview: player.view];
// ...
[player play];
When you use MPMoviePlayerViewController then present the video with presentMoviePlayerViewControllerAnimated: (typically for fullscreen videos).

Answer 2

MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: myURL];
[player.view.frame = self.view.frame];
[self.view addSubview: player.view];
// ...
[player play];

The only magic that worked for me was
- (void) playMovie {
NSURL *url = [NSURL URLWithString:
#"http://www.example.com/video.mp4"];
MPMoviePlayerController *controller = [[MPMoviePlayerController alloc]
initWithContentURL:url];
self.mc = controller; //Super important
controller.view.frame = self.view.bounds; //Set the size
[self.view addSubview:controller.view]; //Show the view
[controller play]; //Start playing
}
In Header file
#property (nonatomic,strong) MPMoviePlayerController* mc;
