如何在iPhone应用程序中播放电影？

Question

我想在我的iPhone应用程序开始处添加一部电影。我看过这些教程，这是我提出的代码。为什么它不工作。我什至不看电影。我把它从我的ViewController与下面的代码viewDidLoad中功能：

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]; 
}

您发起了电影的播放，但没有添加[thePlayer视图]到视图层次，这就是为什么你看不到任何东西。看看这个操作的描述苹果文档：

当您添加的电影播放器​​的看法到应用的视图层次，一定要尺寸框架正确，如下所示：

MPMoviePlayerController *player = 
     [[MPMoviePlayerController alloc] initWithContentURL: myURL]; 
[player.view setFrame: myView.bounds]; // player's frame must match parent's 
[myView addSubview: player.view]; 
// ... 
[player play];
