title: How to animate a view from top to bottom and stacking that view properly?
body: <p>I want to, as properly as possible, animate a view from top to bottom. Then do the appropriate magic to handle memory allocations and such.</p>
  
  <p>In other words, I want an inverse</p>
  
  <pre><code>UIModalTransitionStyleCoverVertical
  </code></pre>
  
  <p>This <code>modalTransitionStyle</code> pops the view up from bottom, while what I'd like it to do is arrive by airplane.</p>
  
  <p>I've looked into some black magic <code>CATransition</code>, but I can't for the life of me find a proper way of handling memory and dismissing (or "popping off") the view with this method.</p>
  
  <p>A solution as close to "as Steve Jobs intended" is much preferred.</p>
  
  <p>PS: The solution does not need to deal with the view as modal. Actually dealing with it as a new "card" on the stack would be best.</p>
