在lua中 怎么能监听到pageView 的翻页事件

#2 
local function pageViewEvent(sender, eventType)
    if eventType == ccui.PageViewEventType.turning then
        local pageView = sender
        local pageInfo = string.format("page %d " , pageView:getCurPageIndex() + 1)
        self._displayValueLabel:setString(pageInfo)
    end
end 

pageView:addEventListener(pageViewEvent)
#3

cocos2dx是2.2.3的
addEventListener没有
ccui.PageViewEventType.turning 没有
该用什么…

#4

cocos2d-x 3.1.1的用
local function pageViewEvent(sender, eventType)
if eventType == ccui.PageViewEventType.turning then
local curPage = self.PageView:getCurPageIndex();
end
end
self.PageView:addEventListenerPageView(pageViewEvent);
