title: UIButton and Swipe Gesture
body: <p>I have a <code>UIView</code> with two <code>UIButton</code>s on each side (left and right) and a <code>UIImageView</code> in the center.  A tap on either button will change the <code>UIImageView</code> and that works.  I want the ability swipe across the <code>UIView</code> as well and it change <code>UIImageView</code>.  Right now, you have to swipe on the <code>UIImageView</code> itself since the <code>UIButton</code>s are catching the input.</p>
  
  <p>I'd like to be able to perform a swipe anywhere on the containing <code>UIView</code> and it performs the transition.  Is there a way to forward touch events such that a swipe can trigger an action, but any other touch is forwarded to the proper subviews?</p>
