title: Reset Constraints for the other components after removing a UIView
body: <p>I got a banner <code>UIView</code> which I want to remove if the user has NoAds Feature.</p>
  
  <p>Problem is after I remove the banner <code>UIView</code>, I cant' find a way to set the constraints of the top view to wrap the rest of <code>ViewController</code>.</p>
  
  <p>Here are some images for you to better understand.</p>

  <p>I remove the banner <code>UIView</code> with <code>removeFromSuperview()</code> method.</p>
  
  <p><strong>On the storyboard, my bottom constraint is set to 0 towards the nearest neighbour which is the <code>UIView</code> banner at the time. Problem is, after I remove the Banner <code>UIView</code>, I want to set the bottom constraint of the above UIView to 0 towards the SuperView.</strong></p>
  
  <p>Thanks in advance.</p>
