title: Indent the text in a UITextField
body: <p>My question is as simple as the title, but here's a little more:</p>
  
  <p>I have a UITextField, on which I've set the background image. The problem is that the text hugs so closely to it's edge, which is also the edge of the image. I want my text field to look like Apple's, with a bit of horizontal space between the background image and where the text starts.</p>
