title: Get X and Y coordinates of a word in UITextView
body: <p>I asked a developer (TwoLivesLeft, the creators of Codea) how they did syntax highlighting in their app. He replied :</p>
  
  <blockquote>
    <p>@TD2 the Codea editor is implemented using a UITextView. The
    highlighting is done by overlaying subviews in the appropriate
    positions — usually UILabels. They are dequeued from a re-use pool,
    similar to the way UITableViewCells work. During scrolling, the lines
    requiring re-highlighting pull markers out of the pool and lines that
    have moved off screen dump their markers back into the pool.</p>
  </blockquote>
  
  <p>Can anyone explain how I would get the x and y of a certain word?</p>
