Question

我正在尝试使用Xcode的一些示例代码在iPhone模拟器5.1下播放mp4视频。我创建了MPMovieViewController和MPMovieController，提供了一个包含mp4的本地路径，并将其作为子视图添加到我的根控制器。

当我在iPhone模拟器下运行它时，只显示后屏幕。我在SO中尝试了几个相同问题的建议，但它仍无效。

以下是代码：

    NSURL *myURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"VIDEO_CX75_01" ofType:@"mp4"]];

    MPMoviePlayerViewController *moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:myURL];        
    MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL: myURL];

    [self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];

    [player.view setFrame: self.view.bounds];  // player's frame must match parent's
    [self.view addSubview: player.view];
    player.view.frame = self.view.frame;

    player.initialPlaybackTime = -1.0;
    [player prepareToPlay];
    [player play];

我做错了什么？

PS：我在使用Xcode 4.3.2

我遇到了同样的问题，而我所做的就是让玩家成为一个强大的属性并合成它。有效。

也适用于您的情况。！

决定并使用MPMoviePlayerViewController 或 MPMoviePlayerController，但不能同时使用。{/ p>

NSURL *myURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"VIDEO_CX75_01" ofType:@"mp4"]];
MPMoviePlayerViewController *moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:myURL];        
[self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];

或

NSURL *myURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"VIDEO_CX75_01" ofType:@"mp4"]]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL: myURL]; player.view.frame = self.view.bounds; [self.view addSubview:player.view]; player.initialPlaybackTime = -1.0; [player prepareToPlay]; [player play];

初始化和播放MPMoviePlayerController返回黑屏
