title: UIScrollView isDragging returns YES when no scrollview is decelerating
body: <p>I want to know if a <code>UIScrollView</code> (<code>UITableView</code>) is dragging (panning) because the user's finger is actively panning it (the user's finger is on the scrollview . i.e. on the screen) or because the scroll view was "flicked" and it is scrolling (i.e 'decelerating' per UIScrollView default behavior)</p>
  
  <p>I tried checking for </p>
  
  <pre><code>[self.tableView isDragging]
  </code></pre>
  
  <p>and unfortunately this returns '<code>YES</code>' in both cases</p>
  
  <p>Then how can I decide if the user's finger is on the 'screen' - and panning?</p>
