使用ui.newEditbox报错

Cocos2d-x
#1

代码如下：

function XXZombieConfScene:addInputBox()
local function onEdit(event, editbox)
if event == “began” then
– 开始输入
elseif event == “changed” then
– 输入框内容发生变化
elseif event == “ended” then
– 输入结束
elseif event == “return” then
– 从输入框返回
end
end

local editbox = ui.newEditBox({
    image = "EditBox.png",
    listener = onEdit,
    size = CCSize(200, 40)
})


editbox:pos(display.cx, display.cy)
editbox:addTo(self)

end

错误如下：LUA ERROR: :106: attempt to index global ‘ui’ (a nil value)

请教各位，是什么问题，使用的是quick-3.2rc1，cocos ide 1.0.0rc2
