applicationMusicPlayer volume notification

I am using an applicationMusicPlayer and when i try to change the volume appear the visual notification, as shown in the picture.
Here the code I am using:

[MPMusicPlayerController applicationMusicPlayer] setVolume:newVolune];


Anyone knows how to hide this notification?

Answer

I don't know where the docs says so, but if you add a MPVolumeView view to your app the system volume overlay goes away. Even if it is not visible:

- (void) viewDidLoad 
{
    [super viewDidLoad];
    MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame: CGRectZero];
    [self.view addSubview: volumeView];
    [volumeView release];
    ...
}

You can use the hardware volume buttons, the setVolume method or directly interact with the control (if visible) that the overlay doesn't show up.
