title: Why shouldn't I subclass a UIButton?
body: <p>I've asked a few questions on stack overflow about subclassing a <code>UIButton</code>, and a couple of people have informed me that I shouldn't subclass a <code>UIButton</code>.</p>
  
  <p>What are the negatives of subclassing a <code>UIButton</code>? And I know it's vague, but what are other alternatives to subclassing a <code>UIButton</code>?</p>
