title: UILabel with different fonts
body: <p>I have this string that I want to display in a label:</p>
  
  <pre><code> NSString *criticsScore=[NSString stringWithFormat:@"%@\%%",[dict objectForKey:@"critics_score"]];
  
   _criticRating.text=criticsScore;
  </code></pre>
  
  <p>I want to set a small font for <code>\%%</code> and a large font for <code>[dict objectForKey:@"critics_score"]];</code><br>
  Is this possible?</p>
