如何获得原始的触摸屏数据？ [英] How to get raw touchscreen data?

问题描述

我知道我可以在我的iPhone应用程序中获得触摸事件。但这些触摸事件为我过滤。如果我将设备按在我的脸上，它会过滤掉这些触摸事件，因为它可以检测到它不是手指。

I know I can get touch events in my iPhone app. But these touch events are filtered for me. If I press the device against my face, it filters out these touch events because it can detect its not a finger.

我如何获得原始触摸事件，而不是以任何方式过滤？

How would I get the raw touch events, not filtered in any way?

推荐答案

没有公共API。你可以得到的最接近的是GSEvent，来自GraphicsServices的私有框架。

There is no public API for this. The closest you can get is GSEvent, from the GraphicsServices private framework.
