title: Horizontal flip direction in iOS Storyboards
body: <p>I have set up two view controllers in my Storyboard, each with an action button. I set up two segues:</p>
  
  <ol>
  <li>From the first view controller to the second view controller: Modal, Flip Horizontal.</li>
  <li>From the second view controller to the first view controller: Modal, Flip Horizontal.</li>
  </ol>
  
  <p>Everything works, but I would like it to flip one way and back, now it flips the same direction for both view controllers.</p>
  
  <p>What is the easiest way to make a flip-flip back effect?</p>
