Question

Im detecting UITableView scrolling in this way

`

  - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate: (BOOL)decelerate{
isDragging_msg = FALSE;
[tblSongs reloadData];

}

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
isDecliring_msg = FALSE;
[tblSongs reloadData]; }


- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView{
isDragging_msg = TRUE;

}

 - (void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView{
isDecliring_msg = TRUE; }

Table view is a scroll view as mentioned here: Is it possible to access a UITableView's ScrollView In Code From A Nib?

So you can just check the scroll view passed in each delegate method whether the scroll view is the table view you want, for example:

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{
    if (scrollView == tblSongs) {
        isDragging_msg = FALSE;
        [tblSongs reloadData];
    }
}

You can detect event on each table. UITableView event

To receive touch events on the UITableView use:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
  //<your stuff>

  [super touchesBegan:touches withEvent:event];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
   //<your stuff>

   [super touchesMoved:touches withEvent:event];
}

- (void)touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event
{
  //<your stuff>

  [super touchesEnded:touches withEvent:event];
}

- (void)touchesCancelled:(NSSet*)touches withEvent:(UIEvent*)event
{
   //<your stuff>
   [super touchesCancelled:touches withEvent:event];
}

and can reload any particular tableview. Thanks
