Finding longPress release Location

Question

I'm Using LongPress on control and drag different positions in views. I found out the starting position using UIGestureRecognizerStateBegan. how do i found out the UIGestureRecognizerStateChanged position?

Answer 1

if( UIGestureRecognizerStateChanged)
{
            CGPoint center = snapshot.center;
            center.y = location.y;
            snapshot.center = center;
}
if (UIGestureRecognizerStateEnded)
{
     location = [longPress locationInView:self.tableView];
}
