  <p>How can i disable this system volume indicator hud?
  My code is :</p>
  
  <pre><code>@property (weak, nonatomic) IBOutlet MPVolumeView *playbackMPVolumeView;
  
  //Customizing controller
  - (void)customizeVolumeController
  {
      _playbackMPVolumeView.showsRouteButton  = YES;
      _playbackMPVolumeView.showsVolumeSlider = YES;
      [_playbackMPVolumeView setVolumeThumbImage:[UIImage imageNamed:@"volume_slider_thumb.png"] forState:UIControlStateNormal];
  }
  </code></pre>
