ios - 如何在我的 ios 应用程序中播放远程 .mp3 文件？

Question

我正在尝试玩遥控器.mp3 file

但它给出了以下错误。

The operation couldn’t be completed. (OSStatus error -43.)

这是我的代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    isPlaying = NO;

/*   

 NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]


pathForResource:@"Dar-e-Nabi-Per" ofType:@"mp3"]];

*/

    NSURL *url = [NSURL 

URLWithString:@"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];

    NSError *error;

    audioPlayer = [[AVAudioPlayer alloc]

                   initWithContentsOfURL:url

                   error:&error];

    if (error)

    {

        NSLog(@"Error in audioPlayer: %@",


              [error localizedDescription]);

 }

 else

 {

   audioPlayer.delegate = self;


   [audioPlayer prepareToPlay];


    }


}

谁能指导我在哪里做错了

Answer 1

要从远程服务器传输音频，请使用 AVPlayer 而不是 AVAudioPLayer。 AVPlayer 文档

示例代码：

- (void)playSampleSong:(NSString *)iSongName {
    NSString *aSongURL = [NSString stringWithFormat:@"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
    // NSLog(@"Song URL : %@", aSongURL);

    AVPlayerItem *aPlayerItem = [[AVPlayerItem alloc] initWithURL:[NSURL URLWithString:aSongURL]];
    AVPlayer *anAudioStreamer = [[AVPlayer alloc] initWithPlayerItem:aPlayerItem];
    [anAudioStreamer play];

    // Access Current Time
    NSTimeInterval aCurrentTime = CMTimeGetSeconds(anAudioStreamer.currentTime);

    // Access Duration
    NSTimeInterval aDuration = CMTimeGetSeconds(anAudioStreamer.currentItem.asset.duration);
}

Answer 2

使用它从 URL 播放歌曲

NSData *songData=[NSData dataWithContentsOfURL:url];

self.player = [[AVAudioPlayer alloc] initWithData:songData error:nil];
    self.player.numberOfLoops=0;
    _player.delegate=self;
    [_player prepareToPlay];
[_player play]
