title: iOS 7 added slide to the right to pop a view controller off the stack. Is it possible to add it back by sliding left?
body: <p>Well, trick question, I know it's possible as there's a few apps doing it, notably <a href="http://reederapp.com/ios/" rel="nofollow">Reeder</a> does it very well.</p>
  
  <p>In Reeder, it seems that the view controller that gets popped does not get removed from memory, or whatever the typical behaviour is, because after popping and returning to the previous view controller, you can slide right-to-left to peek a little, and if you were scrolling the previous view controller before leaving, you can still see the scrolling occur. This ability to quickly jump back to the previous view controllers you were looking at, without having to preload them from scratch is exactly what I'm looking for.</p>
  
  <p>Basically, in iOS 7 by default when you slide to the right from the left edge of a view controller it pops it off the navigation stack. I'd love for the ability to slide to the left from the right edge to add it back. Think of this as in a web browser you're able to click the "Forward" button after pressing back. (Or in iOS 7's Safari how you can do exactly this.)</p>
  
  <p>Is this functionality part of iOS 7 by default and I just can't find it? Or is there any information on how to go about accomplishing it?</p>
