I am making a spin the bottle game. I can’t figure out how to make the bottle’s spin speed controlled by how fast you swipe your finger. I want it to work like the wheel of fortune, the faster you swipe the faster it spins.

    You have to calculate velocity. Which depends on touchesMoved:withEvent: and touchesEnded:withEvent:.
