【问题描述】：

MPMoviePlayerController 几秒钟后停止播放，这是我正在使用的代码：

NSString *urlAddress = @"http://67.159.28.74:8730";
NSURL *url = [NSURL URLWithString:urlAddress];

MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL:url];
player.movieSourceType = MPMovieSourceTypeStreaming;

player.view.hidden = NO;
[self.view addSubview:player.view];
[player prepareToPlay];

if(player){
    [player play];
}

我进入控制台的错误是：

您好，您使用的是哪个 iOS？

【解决方案1】：

解决了：

我把我的 MPMoviePlayerController 变成了一个属性：

//添加标题

@property (strong,nonatomic) MPMoviePlayerController *myPlayer;

//添加到.m文件中

- (IBAction)playStream:(id)sender {
    NSString *urlAddress = @"http://67.159.28.74:8730";
    NSURL *url = [NSURL URLWithString:urlAddress];

    MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL:url];
    [player prepareToPlay];
    //Remember you have to add MediaPlayer.framework to your project
    /*[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:player];*/

    player.movieSourceType = MPMovieSourceTypeStreaming;



    player.view.hidden = YES;

    self.myPlayer = player;

    [self.view addSubview:self.myPlayer.view];


    if(player){
      [self.myPlayer play];
    }
}

【解决方案2】：

你必须像这样设置一个类变量：

@property (nonatomic, retain) MPMoviePlayerController *moviePlayer;

我的代码如下所示：

NSURL *theUrl = [[NSBundle mainBundle] URLForResource:@"test" withExtension:@"mp4"];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theUrl];
[moviePlayer prepareToPlay];
[moviePlayer.view setFrame: self.view.bounds];
moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[self.view addSubview: moviePlayer.view];
[moviePlayer play];

这非常适合我！

在 xCode 4.6.1 上运行良好。

但我在使用 xCode 5 时遇到了这个问题！

但是这个解决方案很有帮助：

"解决方案是播放器必须是视图控制器的实例变量或属性。即我们必须使用 MPMoviePlayerController 的实例

@property (nonatomic,strong) MPMoviePlayerController *myMovieController;"

非常感谢作者！

这是我的代码：

UIGraphicsBeginImageContext(CGSizeMake(1,1));

NSString *path = [[NSBundle mainBundle] pathForResource:@"video" ofType:@"mp4"];
NSURL *videoURL = [NSURL fileURLWithPath:path];
self.moviePlayerView = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
[self.moviePlayerView prepareToPlay];
[self.moviePlayerView.view setFrame:CGRectMake(0, 0, 320, self.view.frame.size.height/2)];
self.moviePlayerView.view.backgroundColor = [UIColor clearColor];
[self.moviePlayerView setContentURL:videoURL];

self.moviePlayerView.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayerView.controlStyle = MPMovieControlStyleDefault;
[self.view addSubview:self.moviePlayerView.view];
self.moviePlayerView.shouldAutoplay = NO;
[self.moviePlayerView play];

UIGraphicsEndImageContext();

【解决方案4】：

您可以在实例化播放器后尝试这样做： [player prepareToPlay]

【讨论】：

不确定我应该在哪里做广告 [player prepareToPlay] ，我的代码中已经有了。我应该将该方法移到其他地方还是添加一个额外的，不确定如何去做。
我在[player play]后面加了[player prepareToPlay]方法，几秒后还是中断了
仍然没有运气我看到其他类似问题的帖子，但问题没有解决。

【解决方案5】：

试试这个，它在 ios6 中很适合我

NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"ddd" ofType:@"mp4"];
NSLog(@"%@",resourcePath);
NSURL *url = [NSURL fileURLWithPath:resourcePath];
NSLog(@"%@",url);
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
moviePlayer.view.frame = self.view.frame;
moviePlayer.moviePlayer.shouldAutoplay=YES;
moviePlayer.moviePlayer.controlStyle = MPMovieControlStyleNone;
[moviePlayer.moviePlayer setFullscreen:YES animated:YES];
[self.view addSubview:moviePlayer.view];
[moviePlayer.moviePlayer play];

【解决方案6】：

这是您缺少的有趣的代码行。

根据苹果的文档

" 当您将电影播放器的视图添加到应用的视图层次结构中时，请确保正确调整帧大小，如下所示：http://tinyurl.com/9wgv9wc

MPMoviePlayerController *player =

    [[MPMoviePlayerController alloc] initWithContentURL: myURL];

[player prepareToPlay];

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

[myView addSubview: player.view];

// ...

[player play];
