title: iOS, how to draw the dynamic length of text?
body: <p>The picture is: <a href="http://www.flickr.com/photos/71607441@N07/6641626163/" rel="nofollow">http://www.flickr.com/photos/71607441@N07/6641626163/</a></p>
  
  <p>The background is a UIImageView, and the blue part I want to show as "title" of the image.
  I used UILabel, but the length of the text is dynamic. It can be one line or two line, at most two line. If the text is longer than two lines, it will be truncated.</p>
  
  <p>The blue part looks like "highlight in Microsoft Word", but it is not "highlight in iOS UILabel.text"</p>
  
  <p>Is there anyone can help me?</p>
