title: Remove Photo/Video Switch in standard UIImagePickerController in order to force user to only take picture
body: <p>I'm trying to find a way to hide the switch inside the standard overlay of the UIImagePickerController (the one at bottom right) because I want to force use to only take picture and not video.
  Is that possible to do it without creating a custom overlay?</p>
  
  <p>Thanks
