AirPlay - programatically disconnect before switching the other device

Question

I have an application for video streaming. It has ability to make mirroring AirPlay (Apple Tv). Now I'm trying to add Google Chromecast connection. I added button and everything working just I expected. Here is my case: I want user only be able to connect 1 device at the moment. For example if user already conneceted to AirPlay when user tap on Chromecast, I want to disable AirPlay programmatically.

Here's how I checked external playback status:

self.videoPlayer.isExternalPlaybackActive

Here's how I checked is AirPlay connected:

- (BOOL)isAirPlayConnected {
    return self.airPlayButton.isWirelessRouteActive;
}

I know this is how I disabled all external display:

self.videoPlayer.allowsExternalPlayback = NO;
self.videoPlayer.usesExternalPlaybackWhileExternalScreenIsActive = NO;

I already listening: MPVolumeViewWirelessRoutesAvailableDidChangeNotification and MPVolumeViewWirelessRouteActiveDidChangeNotification notifications.

Bu couldn't find solution for programatically disconnect before switching the other.

Any help would be appreciated.
