iOS: Airplay picker MPVolumeView alternative

Question

I'm using MPVolumeView to pick airplay device for avplayer airplay playback. Is there any possible non-private API alternative for doing this, so I would be able to provide my own UI Controls for picking airplay device?

By referring to the API, I mean, that all I need is:

1. Ability to reroute audio to airplay-device specific audioRoute.
2. Retrive airplay-device names. (get all available audioRoutes, then get descriptions for airplay audioRoutes)

I know AudioToolbox framework provides some additional API to deal AudioSession, but the only way I found to reroute audio is AVAudioSession's:

- (BOOL)overrideOutputAudioPort:(AVAudioSessionPortOverride)portOverride  error:(NSError **)outError`

which only allows to reroute audio to build-in speakers. Maybe there is some other way how to achieve it there? (I also did only found the way how to retrieve the name of AirplayDevice as a description of the currentAudioRoute - Get name of AirPlay device using AVPlayer)

Answer 1

One should use AVRoutePickerView to manage all audio outputs

For instance, one can make subclass as follows

final class AMRoutePickerView: AVRoutePickerView {
    override init(frame: CGRect) {
        super.init(frame: frame)
        translatesAutoresizingMaskIntoConstraints = false
        tintColor = .clear
        activeTintColor = .clear
    }

    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

Here we hide visual content of this view by setting .clear. Now one can put this view as top subview of any view or button from touchable UI.
