如何检测滑动/轻弹手势？

[英]How do I detect a swiping / flicking gesture?

 原文  2011-07-17 21:25:22  5   1    iphone/ objective-c

问题描述

I want to allow the user to flick a ball that is on screen.我想让用户轻弹屏幕上的球。 The user would tap on the ball and then flick, the velocity / speed of the flick would then dictate initial velocity.用户将点击球然后轻弹，轻弹的速度/速度将决定初始速度。

I took a look at UISwipeGestureRecognizer but it seems like that is more targeted at navigation than flicking.我看了一下UISwipeGestureRecognizer ，但它似乎更针对导航而不是轻弹。

How do I go about implementing this?我该如何实现这个？

I am using Cocos2d and Box2d.我正在使用 Cocos2d 和 Box2d。

Have you considered UIPanGestureRecognizer?你考虑过 UIPanGestureRecognizer 吗？ You can get velocity data from that ([panGesture velocityInView:]), and distinguish the initial velocity of the 'swipe' using the state property on the gesture recognizer.您可以从中获取速度数据 ([panGesture velocityInView:])，并使用手势识别器上的 state 属性区分“滑动”的初始速度。

Or is that not sufficient?或者这还不够？
