如何开发“旋转瓶子”应用 [英] How to develop a "spin the bottle" application

问题描述

我正在开瓶游戏。我无法弄清楚如何通过滑动手指的速度来控制瓶子的旋转速度。我希望它像命运之轮一样工作，你刷的速度越快就越快。

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.

我开始用 UIRotationGestureRecognizer进行开发，但我真的不认为这是最好的方法。

I started to develop with the UIRotationGestureRecognizer, but I really don't think it is the best way to do that.

嘿检查< a href =http://www.walnutlabs.com/blog/?p=9 =nofollow noreferrer>此演示。

你必须计算 velocity 。这取决于 touchesMoved：withEvent：和 touchesEnded：withEvent：。
