title: How to get a UIView under a UIScrollView to detect touches?
body: <p>I have a UIScrollView ontop of my UIViewController recreating an effect like in the Gowalla iPhone app when you're on a spot's page.  Under my scroll view I have a button that I want to be able to perform it's action even when the scroll view's frame covers it up (where it's ontop of the button, the scroll view's clear).  How would I do something like this? Is it possible? (it has to be, Gowalla [somehow] did it)</p>
