title: Disabling iOS volume button shutter
body: <p>I am writing an iOS app that plays music, while the user takes pictures with the camera using <code>UIImagePickerController</code>. However if the user wants to increase the volume, pressing the volume buttons causes a picture to be taken instead. I guess this is because Apple re-purposes the volume buttons to be shutter buttons when the camera image picker is displayed.</p>
  
  <p>Is there a way I can disable the <code>volume button shutter</code> in my app, so that the volume buttons will control the volume even if the camera screen is being displayed?</p>
