UIPinchGestureRecognizer的触摸位置 [英] UIPinchGestureRecognizer's touch locations

问题描述

我想在我的iphone应用程序实现缩放手势缩放。问题是，当一个方法被调用时，手势被识别我没有访问触摸事件本身（所以我不能真正得到他们 locationInView： ），我想得到它，以使我的放大中心正确。

I want to implement zooming with pinch gesture in my iphone app. The problem is, in a method that gets called when the gesture is recognized I don't have access to the touch events themselves (so I can't really get their locationInView:) and I would like to get it in order to center my zoom-in properly.

在 UIPinchGestureRecognizer 类定义中有一个 UITouch * _touches [2]
定义，但我不能从类外面访问它。有什么我可以做，以获得这些数据吗？

In the UIPinchGestureRecognizer class definition there is a UITouch *_touches[2]; defined, but I can't access it from outside of the class. Is there anything I can do in order to get that data?
