Pan和Tap手势识别器相同的视图，另一个需要失败吗?

I need to detect Pan and Tap on the same view, but the tap action is also the first action for pan, so I assume the Tap action need the Pan action to be failed, but then does it make any delay as it has to wait a little bit in order to know if a tap is followed by a movement for a Pan?I need to detect Pan and Tap on the same view,
