Trying to move UIImageView on UIPanGestureRecognizer

Hi Guys I am trying to move UIImageView using the following code on UIPanGestureRecognizer

 CGPoint pointMove;
 pointMove.x = holderView.center.x + (currentPoint.x - lastPoint.x);
 pointMove.y = holderView.center.y + (currentPoint.y - lastPoint.y);

 holderView.center = pointMove;

 lastPoint = currentPoint;

But this is giving a jumble on moving not moving smoothly. Please help me

Try to change this in your code. 

  CGPoint translation = [gestureRecognizer translationInView:[holderView superview]];

    [holderView setCenter:CGPointMake([piece center].x + translation.x, [piece center].y + translation.y)];

I hope this will solve your problem
