local MenuScene = class("MenuScene", function()    return display.newScene("MenuScene")end)function MenuScene:ctor()    print("ctor")local tests = {        "Test_NodeFrameEvent",        "Test_NodeEvent",        "Test_KeypadEvent",        "Test_NodeTouchEvent",        "Test_AccelerometerEvent",        "Test_CocosStudio",        "Test_Audio",    }    local scrollView = ccui.ScrollView:create()    scrollView:addTo(self)    scrollView:align(display.TOP_CENTER, display.cx, display.top)    self.scrollView = scrollView    local total = 0    local btnSize = nil    for i = #tests, 1, -1 do        local btn = ccui.Button:create()        btn:setTitleText(tests[i])        btn:setTitleFontSize(24)        btn:addTouchEventListener(function(sender, eventType)            if 2 == eventType then                print(i)                            end        end)        if not btnSize then            btnSize = btn:getContentSize()        end        btn:pos((display.width - btnSize.width) / 2 + btnSize.width / 2,                btnSize.height * total + btnSize.height / 2)        total = total + 1        scrollView:addChild(btn)    end    local totalHeight = btnSize.height * total    scrollView:setInnerContainerSize(cc.size(display.width, totalHeight))    local scrollHeight = display.height    if totalHeight < scrollHeight then        scrollHeight = totalHeight    end    scrollView:setContentSize(cc.size(display.width, scrollHeight))endfunction MenuScene:onEnter()endfunction MenuScene:onExit()endreturn MenuScene
