判断点击的是哪个精灵

for i=1,#spriteTable do
    --从spriteTable中获取到精灵sprite
     local sprite = spriteTable[i]
     --获取到touch点
     local p = touch:getLocation()
     --获取到精灵的rect
     local rect = sprite:getBoundingBox()
     --判断touch点是否在精灵的范围之内
     local isTouched = cc.rectContainsPoint(rect,p)
     if (isTouched) then
           --todo
          print(obj.object[i].KindName)
     else
     print("未在有效区域")
     end
end
