title: ios7 - how do I set uibutton title to superscript?
body: <p>I have tried to use this <a href="https://stackoverflow.com/questions/10407012/how-do-i-superscript-characters-in-a-uibutton">question</a> to create a UIButton that has a title of 2 squared.But I can't get it to work. What am I missing?</p>
  
  <p>My code is virtually identical:</p>
  
  <pre><code> if (button.tag == 200)
          [button setTitle: @"x\u00B3 + x\u00B2 + x\u00B9 + k" forState: UIControlStateNormal | UIControlStateHighlighted | UIControlStateSelected];
  </code></pre>
  
  <p>Thanks in advance</p>
