title: How to make a button fade after clicked for iOS / xcode?
body: <p>I want to make a button fade away after it is clicked. I know that I can use</p>
  
  <pre><code>_myButon.hidden = TRUE;
  </code></pre>
  
  <p>...to completely hide a button, but it feels abrupt and jarring. I also know I could sequentially lower the alpha or something, but wasn't sure how to make this happen automatically over a short period of time.</p>
  
  <p>Can someone please give me a tip how to fade out a button after it is clicked using the simplest means possible? I want the effect to look something like a simple "Fade-out" from a powerpoint presentation or something :)</p>
  
  <p>Thanks!</p>
