How can I get current audio URL playing inside my app from WKWebView?

Question

I have a WKWebView and I am checking if audio is playing using

[[AVAudioSession sharedInstance] isOtherAudioPlaying] 

I tried to get some information about it using :

  [MPNowPlayingInfoCenter defaultCenter] nowPlayingInfo]

but it was nil.

Then I tried:

 [[MPMusicPlayerController systemMusicPlayer] nowPlayingItem]

and it was also nil.

How can I get URL of current playing audio?

You need to subscribe on notification :

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

And then do this inside method playerItemBecameCurrent

-(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];}
