iOS:实现实时音频流的正确方法是什么？

Question

我正在为新闻网站开发 iOS 应用程序，该网站有 a live audio news channel ，我尝试使用 AVAudioPlayer 并执行了以下操作:

.h文件:

@interface ViewController : UIViewController <AVAudioPlayerDelegate>
@property (strong, nonatomic) AVAudioPlayer *audioPlayer;

.m 文件(viewDidLoad):

- (void)viewDidLoad {
    [super viewDidLoad];
    NSURL *url = [NSURL fileURLWithPath:@"http://198.178.123.23:8662/stream/1/;listen.mp3"];

    NSError *error;
    _audioPlayer = [[AVAudioPlayer alloc]
                    initWithContentsOfURL:url
                    error:&error];
    if (error)
    {
        NSLog(@"Error in audioPlayer: %@",
              [error localizedDescription]);
    } else {
        _audioPlayer.delegate = self;
        [_audioPlayer prepareToPlay];
    }
}

但是应用程序给我以下错误:

2015-05-25 15:03:12.353 AudioPlayer[2043:421434] Error in audioPlayer: The operation couldn’t be completed. (OSStatus error 2003334207.)

我不知道这段代码有什么问题。

谁能告诉我代码中的错误在哪里？

非常感谢。

我认为有一种更好的方法可以在带有音频 url 的默认 MPMoviePlayer 中播放音频链接。其余的事情将由默认播放器管理。

编辑:

    NSURL *audioPath = [NSURL URLWithString:@"Your Audio URL"];

    MPMoviePlayerViewController *mpViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:audioPath];
    // Remove the movie player view controller from the "playback did finish" notification observers
    [[NSNotificationCenter defaultCenter] removeObserver:mpViewController
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:mpViewController.moviePlayer];

    // Register this class as an observer instead
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(movieFinishedCallback:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:mpViewController.moviePlayer];

    // Set the modal transition style of your choice
    mpViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

    // Present the movie player view controller
    [self presentViewController:mpViewController animated:YES completion:nil];

    // Start playback
    [mpViewController.moviePlayer prepareToPlay];
    [mpViewController.moviePlayer play];
