Question

我想在我的iphone应用中播放一段简短的视频。当我使用下面的代码时，我只听到音频并看到应用程序的常规视图。我想让视频在这个视图之上播放。我该怎么办？

    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

请勿混淆MPMoviePlayerController和MPMoviePlayerViewController。当您使用MPMoviePlayerController时，请使用它（通常用于iPad上的嵌入式视频）：

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

当您使用MPMoviePlayerViewController时，会使用presentMoviePlayerViewControllerAnimated:（通常用于全屏视频）展示视频。

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

对我有用的唯一魔力是

 - (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
}

在页眉文件中

@property (nonatomic,strong) MPMoviePlayerController* mc;
