Can I mute for youtube-ios-player-helper?

Question

I'm using youtube-ios-player-helper to play youtube video in my application. I'd like to be able to mute. Here is what I did:

1. Add setVolume() and mute() function in YTPlayerView

   -(void)setVolume:(int)volume {
   
       if ( volume < 0 )
           volume = 0;
       else if ( volume > 100 )
           volume = 100;
       NSString *command = [NSString stringWithFormat:@"player.setVolume(%d);", volume];
       [self stringFromEvaluatingJavaScript:command];
   }
   
   -(void)mute {        
       NSString *command = [NSString stringWithFormat:@"player.mute();"];
       [self stringFromEvaluatingJavaScript:command];
   }
   

Then I call setVolume:0 or mute functions in my app. But the sound can't be turned off. The volume is still 100.

Did anybody turn off the sound successfully?

Following the above I got it working in Swift4:

func playerView(_ playerView: YTPlayerView, didChangeTo state: YTPlayerState) {
    if case .playing = state {
        playerView.webView?.stringByEvaluatingJavaScript(from: "player.mute();")
    }
}
