如何获取多点触控 UITapGestureRecognizer 的多个位置 [英] How to get multiple locations of multi touch UITapGestureRecognizer

问题描述

在我看来，我有一个 UITapGestureRecognizer，我可以用下面的代码很好地获得它的接触位置.现在，如果我将此识别器的触摸次数更改为 2(或更多)，它仍然会给我一个位置.如何获得两次触摸的两个位置?

I have a UITapGestureRecognizer in my view and I can get the location of its touch with below code fine. Now if I change this recognizer's number of touches to 2 (or more), it still gives me one location. How can I get two locations of the two touches?

tapGesture.locationInView(self.view)

请尽快帮助.

推荐答案

不使用 locationInView，而是使用 locationOfTouch 来获取每次点击的位置:

Instead of using locationInView, use locationOfTouch to get the location of each tap:

let tapLocation1 = tapGesture.locationOfTouch(0, inView: self.view)
let tapLocation2 = tapGesture.locationOfTouch(1, inView: self.view)
