UIScrollView isDragging returns YES when no scrollview is decelerating

Question

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?

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

Or

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

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

Try using uiscrollView Delegate. You will get call here when user is panning

– scrollViewDidScroll:
