UIScrollView isDragging returns YES when no scrollview is decelerating

I want to know if a UIScrollView (UITableView) 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)

I tried checking for 

[self.tableView isDragging]

and unfortunately this returns 'YES' in both cases

Then how can I decide if the user's finger is on the 'screen' - and panning?

Using your scroll view delegate you are achieve this. 

 - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate;
 - (void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView;   
// called on finger up as we are moving

 - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView; here

Instead of using isDragging use isTracking for touch recognising on UITableView.

Or

if you want to recognize dragging ofUITableview use scrollview delegate methods.
