我在哪里可以获得相位UITouchPhaseStationary的触摸事件？ [英] Where can I get a touch event with phase UITouchPhaseStationary?

问题描述

在这些方法中，我得到了相应的阶段：

touchesBegan：withEvent：UITouchPhaseBegan，

touchesMoved：withEvent：UITouchPhaseMoved，

touchesEnded：withEvent：UITouchPhaseEnded ，

touchesCancelled：withEvent：UITouchPhaseCancelled。

In these methods, I get corresponding phases:
touchesBegan:withEvent: UITouchPhaseBegan,
touchesMoved:withEvent: UITouchPhaseMoved,
touchesEnded:withEvent: UITouchPhaseEnded,
touchesCancelled:withEvent: UITouchPhaseCancelled.

在这个阶段我可以在哪里获得触摸事件： UITouchPhaseStationary ？

Where can I get a touch event with this phase: UITouchPhaseStationary?

推荐答案

您可以假设在2 已移动事件之间的时间内触摸静止。

You can assume a touch in the time between 2 Moved events as stationary.

（ UITouchPhaseStationary 因多点触控而存在。如果一根手指移动而另一根没有，则移动事件仍然被触发，但静止触摸将处于 UITouchPhaseStationary 阶段。）

(UITouchPhaseStationary exists because of multitouch. If one finger moves while the other doesn't, a Moved event is still triggered, but the stationary touch will be in the phase UITouchPhaseStationary.)
