VolumeButtonsListener

With this little class, you would be able to listen and handle events produced by the volume buttons.

I am aware that internally, this is a 'hackish' approach, but I tried to find better solutions and I couldn't. Please, if you discover a proper way to do it, let me know =)

Instructions

Call the following function only once, for example in the didFinishLaunchingWithOptions, not to show the HUD when buttons are pressed.

VolumeButtonsListener.hideVolumeHUD()

Start listening, (f.e: viewWillAppear, UIApplicationDidBecomeActive):

VolumeButtonsListener.listen(){ 
	// Do your stuff here
}

And finally, when you are done (f.e: viewWillDisappear, UIApplicationDidEnterBackground).

VolumeButtonsListener.stopListen()

Please, feel free to suggest improvements!

Thanks Henk for your necessary help.
