Get the original center point. CGPoint oldCenterPoint ccp scaleCenter.x yourLayer.scale scaleCenter.y yourLayer.scale Set the scale. yourLayer.scale newScale Get the new center point... scaleCenter.y yourLayer.scale Set the scale. yourLayer.scale newScale Get the new center point. CGPoint newCenterPoint ccp scaleCenter.x yourLayer.scale scaleCenter.y yourLayer.scale Then calculate the delta. CGPoint centerPointDelta ccpSub oldCenterPoint..
