title: How much contentOffset changes in UIScrollview for zooming?
body: <p>In UIScrollview, when I scroll/drag, I got changes in scrollview contentOffset which represent how much I had scrolled/dragged in the scrollview. By this way, I have updated the subview of scrollview for scrolling.</p>
  
  <p>But, when I zoom the scrollview (using pinch zooming), the contentOffsets of the scrollview is also changed. I do not understand how much contentOffset has changed because I can not relate  the changes with zoomScale value. So, is there anyway to know changes in contentOffset for zooming?</p>
  
  <p>My intention is get the value of contentOffset changes for dragging while zooming (which is not I am getting because of zooming content offset changes) so that I can update my scrollview's subview accordingly.</p>
  
  <p>I am stuck in here. Any help will be very much appreciated. </p>
  
  <p>thanks</p>
