title: iOS: UIScrollView detecting Swipe Gesture
body: <p>I have an UIScrollView which scrolls automatically by using a timer, which scrolls every 3 seconds to the next page (kind of slideshow).</p>
  
  <p>Now I want to implement a function which detects any user interaction, to cancel the timer as soon as the user interacts with the scrollview, so that he can scroll through the scrollview by himself.</p>
  
  <p>What would be the best way to do this?
  The ScrollView isn't subclassed and is using the UIScrollViewDelegate.</p>
  
  <p>Would be glad for some hints.
  Cheers.</p>
