title: Unable to satisfy constraints warning on hiding element
body: <p>I have UIView with some UI items inside it (Buttons, Labels...). There are constraints that help to fix this items.</p>
  <p>I also have button for collapsing UIView. In this case UIView height is decreased and all UI Items inside it become hidden.</p>
  <p>When I do it I have many warnings from Xcode in output section:</p>
  <blockquote>
  <p>Unable to simultaneously satisfy constraints......</p>
  <p>Will attempt to recover by breaking constraint....</p>
  </blockquote>
  <p>What can I do with it?</p>
