title: How to sync scroll with multiple UIScrollViews?
body: <p>I have 2 UIScrollViews displaying an image each (overview and zoom mode). I can scroll in both views already individually, now I want to keep the centerpoint of both views in sync.</p>
  
  <p>I guess when one of the views is creating events, I need to forward them also to the other view, just can't find out which functions are relevant. Any hints? </p>
  
  <p>edit: If parallel live scrolling is not possible, I want to at least sync after a scroll event.</p>
