问题描述
我有一个UIView子类，该子类重写了UIResponder的touchesMoved:消息.我注意到，当我在UIView上快速滑动手指时，touchesMoved:消息只会每隔一段时间被调用一次，而不会不断得到消息.
I have a UIView subclass that overrides UIResponder's touchesMoved: message. I've noticed that when I swipe my finger very quickly across the UIView, my touchesMoved: message only gets called every so often and not constantly getting messaged.
有什么想法吗?
谢谢.
