title: How do I make a UISwitch under iOS 7 not take the background colour of the view behind it?
body: <p>It looks like this whenever off:</p>
  
  <p><img src="https://i.stack.imgur.com/tprEb.png" alt="enter image description here"></p>
  
  <p>While I'd prefer more of a grey background. Do I really have to use a UIImageView?</p>
