Question

我想知道为什么我的AVPlayer在我想播放“一些”歌曲时会崩溃。

这就是我播放这些歌曲的方式：

AVPlayerItem *item = [[AVPlayerItem alloc] initWithURL:[NSURL URLWithString:@"http://www.iwheelbuy.com/Player/Test/1.mp3"]];
AVPlayer *player = [[AVPlayer alloc] init];
[player replaceCurrentItemWithPlayerItem:item];
[player setRate:1.0f];

我有一些KVO观察员，其中一个观察AVPlayer status，当我尝试播放其中一首歌时，它给了我一个错误：

Domain=AVFoundationErrorDomain Code=-11800
UserInfo=0x1cdc3be0 {NSLocalizedDescription=..., NSUnderlyingError=0x1cdc14c0
"The operation couldn’t be completed. (OSStatus error -303.)"

有没有办法播放这些歌曲？任何帮助表示赞赏。

编辑：我成功地让这些歌曲发挥得很好

__block AVPlayer *currentPlayerBlock = _currentPlayer;
__block NSURL *urlBlock = url;
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
    AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:urlBlock options:nil];
    AVPlayerItem *item = [[AVPlayerItem alloc] initWithAsset:asset];
    dispatch_sync(dispatch_get_main_queue(), ^{
        [currentPlayerBlock replaceCurrentItemWithPlayerItem:item];
        [currentPlayerBlock setRate:1.0f];
    });
});

__block AVPlayer *currentPlayerBlock = _currentPlayer;
__block NSURL *urlBlock = url;
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
    AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:urlBlock options:nil];
    AVPlayerItem *item = [[AVPlayerItem alloc] initWithAsset:asset];
    dispatch_sync(dispatch_get_main_queue(), ^{
        [currentPlayerBlock replaceCurrentItemWithPlayerItem:item];
        [currentPlayerBlock setRate:1.0f];
    });
});

这种方式有效
