title: Braintree drop-in UI (iOS)
body: <p>I am trying to customize the appearance of the Braintree drop-in VC:</p>
  
  <p><a href="https://i.stack.imgur.com/OsOOv.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OsOOv.jpg" alt="BT drop-in UI"></a></p>
  
  <p>E.g. apply clear background color or background image to the whole thing. I can't seem to nail it. For instance, there's no backgroundView property to set an image to since it's a static UITableView.</p>
  
  <p>Also, I can see there's support for themes..?</p>
  
  <p>Has anyone successfully managed to customise the drop-in on top of the basic things that you can do as per <a href="https://developers.braintreepayments.com/guides/drop-in/ios/v3" rel="nofollow noreferrer">Braintree's guide</a>?</p>
