title: Two finger swipe gesture
body: <p>Apple has some sample code <a href="http://developer.apple.com/iphone/library/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/EventHandling/EventHandling.html#//apple_ref/doc/uid/TP40007072-CH9-SW1" rel="nofollow noreferrer">here</a> under "detecting swipe gestures".</p>
  
  <p>I'd like to detect a two swipe gesture for my application but have no idea where to start. Surprisingly enough I wasn't able to find any samples/examples of similar code. Is there something inherently difficult about the code? Any links or tips you are willing to share would be great.</p>
