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.)
