爲便於看客實際操作和理解，直接上例子
demo中要調用父類中的函數和表，固先列出父類中響應的函數和表
local resPathes =
{
s_pPathB1 = "Images/b1.png",
s_pPathB2 = "Images/b2.png",
s_pPathR1 = "Images/r1.png",

s_pPathF2 = "Images/f2.png",
s_arialPath = "fonts/arial.ttf"
}
ArmatureTestLayer.resPathes = resPathes
local ArmatureTestIndex =
{

end
function ArmatureTestLayer.subTitle(idx)
if ArmatureTestIndex.TEST_ASYNCHRONOUS_LOADING == idx then

return "Move to a mount and press the ChangeMount Button."
else
return ""
end
end目標類調用父類的函數已經列出，下面是目標代碼
local ArmatureTestLayer = require("layers.ArmatureTestLayer")
local TestAsynchronousLoading = class("TestAsynchronousLoading", ArmatureTestLayer)
function TestAsynchronousLoading:ctor()
TestAsynchronousLoading.super.ctor(self)
end
function TestAsynchronousLoading:onEnter()
--設置在父類中定義的三個按鈕可以點擊
self.prevButton:setButtonEnabled(false)
self.restartButton:setButtonEnabled(false)
self.nextButton:setButtonEnabled(false)
--設置標題 self.title(1) 獲取父類標題表中對應的字符串 self.resPathes.s_arialPath 獲取字體文件
local title = cc.Label:createWithTTF(self.title(1), self.resPathes.s_arialPath, 18)
title:setColor(cc.c3b(0,0,0))
self:addChild(title, 1, 10000)
title:setAnchorPoint(cc.p(0.5, 0.5))
title:setPosition( display.cx, display.top - 30 )
--設置顯示進度的title
local subInfo = self.subTitle(1)
if "" ~= subInfo then
subInfo = subInfo .. 0.0
local subTitle = cc.Label:createWithTTF(subInfo, self.resPathes.s_arialPath, 18)
subTitle:setColor(cc.c3b(0,0,0))
self:addChild(subTitle, 1, 10001)
subTitle:setAnchorPoint(cc.p(0.5, 0.5))
subTitle:setPosition( display.cx, display.top - 60 )
end
--創建進度條
local timer = cc.ProgressTimer:create(cc.Sprite:create("loading.png"))
timer:setPosition(display.cx, display.cy)
timer:setBarChangeRate(cc.p(1,0))
timer:setType(display.PROGRESS_TIMER_BAR)
timer:setMidpoint(cc.p(0,0.5))--基準點
timer:setPercentage(0)
self:addChild(timer, 50, 10002)
local function dataLoaded(percent)
--獲取進度條
local timer1 = self:getChildByTag(10002)
--獲取進度顯示title
local label = self:getChildByTag(10001)
if nil ~= label then
--設置進度條進度
timer1:setPercentage(percent*100)
local subInfo = self.subTitle(1) .. (percent * 100)
label:setString(subInfo)
end
--加載完成，界面上的按鈕纔可以點擊
if percent >= 1 and self.prevButton and self.restartButton and self.nextButton then
self.prevButton:setButtonEnabled(true)
self.restartButton:setButtonEnabled(true)
self.nextButton:setButtonEnabled(true)
end
end
local manager = ccs.ArmatureDataManager:getInstance() --addArmatureFileInfoAsync適用異步加載骨骼動畫資源 --addImageAsync適用異步加載圖片資源對比cocos2d-x中的資源加載，Quick中在每次加載完資源之後不需要手動更新百分比數 （ cocos2d-x中 float percent=100*res_count/15.0;//一共需要加載15次（因爲有15個文件）） Quick中把這些操作都封裝完成。
