How to hide "Now playing url" in control center

I am trying to hide livestream urls that are playing in an UIWebView. When you play a livestream url and open control center (iOS) you see the url that is playing:

.

I would like to hide that with a HTML-based or xcode-based script.

You can control this information with the MPNowPlayingInfoCenter. The defaultCenter's nowPlayingInfo dictionary controls what is displayed about the current audio track on the lock screen and command center.

MPNowPlayingInfoCenter *infoCenter = [MPNowPlayingInfoCenter defaultCenter];

NSDictionary *nowPlayingInfo = @{
                                 MPMediaItemPropertyTitle : @"Media Name",
                                 MPMediaItemPropertyArtist : @"Media Artist"
                                 };

[infoCenter setNowPlayingInfo:[NSDictionary dictionaryWithDictionary:nowPlayingInfo]];

The full list of keys are listed in the docs, but it looks like you want to set the track name to the empty string.

MPMediaItemPropertyTitle : @""
