几秒钟后,MPMoviePlayerController停止播放

Question

MPMoviePlayerController 几秒后停止播放,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];
}

进入控制台的错误是:

Answer 1

解决了它:

我把我的MPMoviePlayerController变成了一个属性:

//添加标题

@property (strong,nonatomic) MPMoviePlayerController *myPlayer;

//添加.m文件

- (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];
    }
}

Answer 2

你必须像这样设置一个类变量:

@property (nonatomic, retain) MPMoviePlayerController *moviePlayer;

我的代码看起来像这样:

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];

这对我来说很完美!

您可以在实例化播放器后尝试执行此操作： [player prepareToPlay]
