Answer 1

For me, on iOS 7, none of above solutions worked. Here is how I did it:

_volume = [[MPVolumeView alloc] initWithFrame: CGRectMake(-100,-100,16,16)];
_volume.showsRouteButton = NO;
_volume.userInteractionEnabled = NO;
[self.view addSubview:_volume];
[_volume release];

That is, simply set MPVolumeView's frame to an off-screen location such as (-100,-100).
