初次使用quick 3.3版本--listview 判断是否到达边界 isItemInViewRect

在quick 3.3里面存在isItemInViewRect方法判断是否在可视区域，isItemInViewRect 源代码修改如下即可

function UIListView:isItemInViewRect(pos)
local item
if "number" == type(pos) then
item = self.items_[pos]
elseif "userdata" == type(pos) then
item = pos
end


if not item then
return
end

local bound = item:getBoundingBox()
local nodePoint = self.container:convertToWorldSpace(
cc.p(bound.x, bound.y))
bound.x = nodePoint.x
bound.y = nodePoint.y


local viewRectPos = self:convertToWorldSpace(cc.p(self.viewRect_.x,self.viewRect_.y))  
    local viewRect = cc.rect(viewRectPos.x,viewRectPos.y,self.viewRect_.width,self.viewRect_.height)  


return cc.rectIntersectsRect(viewRect, bound)
end

源代码只把item坐标转化成世界坐标，但是没有将viewRect_转化成世界坐标
