推荐答案

有一种hacky方式它通过侦听 AVPlayerItemBecameCurrentNotification 通知。当UIWebView显示媒体播放器时会触发此通知，并且它会发送 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，我注意到你提到了YouTube - 如果它能够下载YouTube视频全部，那么值得指出Apple WILL 拒绝你的应用，因为它反对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.
