title: Xcode IB: UIButton hidden but have still buttons space
body: <p>I have the following issue in my iPhone app.
  I have 4 buttons in my IB also linked to my <code>UIViewController</code> (<code>IBOutlet</code>)
  When I for example hide the second button which is <em>AfvalSoorten</em> with <code>[self.btnAfvalSoorten setHidden:YES];</code> then it disappears, that's what I want, but I still got the button space when I debug the app on the simulator.</p>
  <p>How can I get rid of that?
  Below there is an example.</p>

  <p>Is there an option on the Storyboard for the buttons to clip together?</p>
