title: iOS7 UITextView auto resize text
body: <p>I have a UITextView inside a storyboard. The text displayed is localised and can vary in length. I'm looking for a way to resize the font size down until the text fits.</p>
  
  <p>The box can't grow in actual height so a reduction in font size is required.</p>
  
  <p>Can't see anything in IB that allows for this. Thought so far which feels ugly is to measure the contentSize.height against the frame.size.height reducing the font size by 1 each time until it fits. </p>
