Is there any way to get the link of currently playing video.I am loading m.youtube.com .For some videos it is not even entering the delegates.I tried using a NStimer as well.But for some videos it is not the clicked url

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.

For example:

[[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];
}

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.

This one is for swift version:

//Add NSNotificationcenter for current playing song

override func viewDidAppear(_ animated: Bool) {
    NotificationCenter.default.addObserver(self, selector:#selector(playerItemBecameCurrent), name:NSNotification.Name(rawValue: "AVPlayerItemBecameCurrentNotification"), object:nil)
}

//Fetch path from notificationcenter

@objc func playerItemBecameCurrent(notification:NSNotification){
    let playerItem:AVPlayerItem = notification.object as! AVPlayerItem
    let asset:AVURLAsset=playerItem.asset as! AVURLAsset
    let url = asset.url
    let path = url.absoluteString
    print(path)

}
