Mute sound in Xamarin.iOS (iOS version >11)

Question

I am using XamarinMediaManager (built using MPMusicPlayerController) to Build an audio player for iOS, i am looking for a way to mute the sound on a button click, this works perfectly on iOS 9:

MPMusicPlayerController.ApplicationMusicPlayer.Volume = 0

But it looks like it is deprecated on newer versions: https://developer.apple.com/documentation/mediaplayer/mpmusicplayercontroller/1624567-volume

How to achieve the same thing using another way? (i am not looking to build an entire volume manager, i just want to set the volume).

Any help would be appreciated.

According to the documentation posted it's been deprecated for MPVolumeView, which is their new slider view for adjusting audio output. I know you're not looking to add the slider to your UI and want to do it programmatically, which based on this post you can still technically do it. Although, it does feel kind of hacky.

Here is the C# equivalent:

UISlider slider = null;
var volumeView = new MPVolumeView();
foreach (var view in volumeView.Subviews)
{
    if (view is UISlider)
    {
        slider = (UISlider)view;
        break;
    }
}

slider.Value = 0;

It's worth noting I'm unsure whether if this will actually effect how XamarinMediaManager is playing the audio.

Unfortunately, i couldn't get this to work on iOS 11 :// – May 29 '18 at 13:33
In that case, you may have to write your own instead of using `XamarinMediaManager` – Nick Peppers May 29 '18 at 14:05
