推荐答案

通过监听 AVPlayerItemBecameCurrentNotification 通知有一个 hacky 方法.当 UIWebView 显示媒体播放器时会触发此通知，并发送 AVPlayerItem 作为通知的对象.

There is a hacky way of doing it by listening for the AVPlayerItemBecameCurrentNotification notification. This notification is fired when a UIWebView shows the media player, and it sends an AVPlayerItem as the notification's object.

例如:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemBecameCurrent:)
                                             name:@"AVPlayerItemBecameCurrentNotification"
                                           object:nil];


-(void)playerItemBecameCurrent:(NSNotification*)notification {
    AVPlayerItem *playerItem = [notification object];
    if(playerItem == nil) return;
    // Break down the AVPlayerItem to get to the path
    AVURLAsset *asset = (AVURLAsset*)[playerItem asset];
    NSURL *url = [asset URL];
    NSString *path = [url absoluteString];
}

这适用于任何视频(和音频).但是，我注意到您提到了 YouTube - 值得指出的是，如果 Apple 将拒绝您的应用，如果它能够完全下载 YouTube 视频，因为它违反 YouTube 的服务条款.

This works for any video (and audio). However, I noticed you mentioned YouTube - it's worth pointing out Apple WILL reject your app if it has the ability to download YouTube videos AT ALL, because it's against YouTube's Terms of Service.
