我在聊天应用程序中使用AVPlayer但是我在选定的音频文件中遇到了错误但是音频文件在浏览器中正确播放.

错误域= AVFoundationErrorDomain代码= -11800"操作无法完成"UserInfo = {NSUnderlyingError = 0x60800024fde0 {Error Domain = NSOSStatusErrorDomain Code = -16170"(null)"},NSLocalizedFailureReason =发生未知错误(-16170),NSLocalizedDescription =操作无法完成}

-(void)setupAVPlayerForURL:(NSURL*)url

    AVPlayerItem *anItem = [AVPlayerItem playerItemWithAsset:asset];
    playerAud = nil;
    playerAud = [AVPlayer playerWithPlayerItem:anItem];
    [self startTimer];
    [playerAud play];
    [anItem addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stopAudioPlay) name:AVPlayerItemDidPlayToEndTimeNotification object:nil];
}

And also implement the fallowing observer.

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    //// playerAud is instance of AVPlayer 
    if (object == playerAud.currentItem && …
