title: What's the best way to develop a sideswipe menu like the one in Facebook's new iOS app?
body: <p>It appears that side-swipe menus are becoming a more common interface element as more information gets crammed into each iPhone app.  Facebook has included it in their latest version and <a href="http://www.theverge.com/2011/11/2/2533321/gmail-ios-hands-on" rel="noreferrer">the new Gmail app appears to include it as well</a>.  I was wondering if anybody had thoughts on the most efficient way of developing something like this as it's becoming a more common interface element.   While I have my own thoughts on how to build this, I'm curious to hear what other people think.</p>
