title: UIButton inherit selected state
body: <p>I have a <code>UIButton</code> inside a custom cell. Upon selecting the cell, the button changes it state to <em>"highlighted"</em> as well. </p>
  
  <p>I'd like to prevent that behaviour. The button should change its state only when it's specifically touched (I take care of that in my <code>IBAction</code>). </p>
  
  <p>Is it possible?</p>
