title: Changing UIButton text
body: <p>So I'm trying to update the text on a UIButton when I click it. I'm using the following line to change the text:</p>
  
  <pre><code>calibrationButton.titleLabel.text = @"Calibration";
  </code></pre>
  
  <p>I have verified that the text is changing, but when I run the app and I click on the button, it changes to "Calibration" for a split second and then goes right back to its default value.  Any ideas why this might be happening? Is there some sort of refresh function I need to be calling?</p>
