cocos2dx3.10 带滚动条的ScrollView和TableView

概述scroview有2个虚方法： virtual void scrollViewDidScroll(ScrollView* view)：这是当scrollView在被拖动时会响应该函数； virtual void scrollViewDidZoom(ScrollView* view)：这是当scrollView在进行缩放时会响应该函数; self._ScrollView = self:getWidg

scrovIEw有2个虚方法：

virtual voID scrollVIEwDIDScroll(ScrollVIEw* vIEw)：这是当scrollVIEw在被拖动时会响应该函数；

virtual voID scrollVIEwDIDZoom(ScrollVIEw* vIEw)：这是当scrollVIEw在进行缩放时会响应该函数;
