How do you play a movie in an iphone app? - iphone

Question

I want to add a movie at the beginning of my iphone app. I have watched the tutorials and this is the code I have come up with. Why won't it work. I don't even see a movie. I call it from the viewDidLoad function of my ViewController with the following code:
NSString *path = [[NSBundle mainBundle] pathForResource:#"BTS Intro" ofType:#"mov"];
[self playMovieAtURL:[NSURL fileURLWithPath:path
-(void)playMovieAtURL:(NSURL *)theURL {
MPMoviePlayerController *thePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theURL];
thePlayer.scalingMode = MPMovieScalingModeAspectFill;
thePlayer.controlStyle = MPMovieControlStyleNone;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(myMovieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:thePlayer];
[thePlayer play];
}
-(void)myMovieFinishedCallback:(NSNotification *)aNotification {
MPMoviePlayerController *thePlayer = [aNotification object];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:thePlayer];
[thePlayer release];
}

Answer 1

You initiated playing of a movie but didn't add [thePlayer view] into views hierarchy that is why you do not see anything. Take a look at description of this operation in apple docs:
When you add a movie player’s view to your app’s view hierarchy, be sure to size the frame correctly, as shown here:
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: myURL];
[player.view setFrame: myView.bounds]; // player's frame must match parent's
[myView addSubview: player.view];
// ...
[player play];
