实现上面布局的方式：
相对布局：
先把1的位置写死，然后2相对于1，x+偏移量，y不变
4相对于 1，y+偏移量。
伪代码：
local tmpNode = CCNode:create()
local basePoint = ccp(0,0)
for i=1,#tmpItemInfoTables do
local tmpItemInfo = tmpItemInfoTables[i]
local itemView= self:createSingleItemView(tmpItemInfo) -- 创建单个view
itemView:setAnchorPoint(ccp(0,1))
itemView:setPosition(ccp(basePoint.x,basePoint.y))
tmpNode :addChild(itemView)
if math.fmod(i,3) == 1 then
basePoint = 获取itemView右上角的坐标
basePoint = ccp(basePoint.x+15,basePoint.y)
elseif math.fmod(i,3) == 2 then
basePoint = 获取itemView右上角的坐标
basePoint = ccp(basePoint.x+15,3) == 0 then
basePoint = 获取itemView左下角的坐标
basePoint = ccp(0,basePoint.y-10)
end
end
