cocos2dx3.10 带滚动条的ScrollView和TableView

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:getWidget("ScrollView_1")
   -- self._ScrollView:setInertiaScrollEnabled(false)

   self._slider = self:getWidget("Slider_1")

    local function percentChangedEvent(sender,eventType)

            local percent = slider:getPercent()
            self._ScrollView:jumpToPercentVertical(percent)
