2.2.6的addSearchPath多次会导致卡顿的BUG

Cocos2d-x Lua

BUG描述在3楼

https://github.com/chukong/quick-cocos2d-x/blob/c0c29ebab139db10a7af50a8b1270fe7bdc86dce/framework/cc/uiloader/CCSUILoader.lua

function CCSUILoader:parserJson(jsonVal)
    local root = jsonVal.nodeTree
    if not root then
        root = jsonVal.widgetTree
    end
    if not root then
        printInfo("CCSUILoader - parserJson havn't found root node")
        return
    end
    print("test LoadCCSJSON ----  parserJson xxxx1111  " )
    self:prettyJson(root)
    print("test LoadCCSJSON ----  parserJson 22222  " )
    local uiRoot = self:generateUINode(root)
print("test LoadCCSJSON ----  parserJson 3333  " )
    return uiRoot, root.options.adaptScreen
end

发现多次读取ＪＳＯＮ文件后(几十次差不多) ，变的巨卡无比：有数据对比：

第一次的时候，self:generateUINode只用了 0.16秒．．．

几十次读取后：变成 0.76秒 ，很是恐怖

发觉读取文件完全不是瓶颈～～～，是非常的快，哪怕几十次之后，解析成显示对象就是个慢的地方


-- private
function uiloader:loadFile_(jsonFile)

    print("test LoadCCSJSON ----  uiloader11111 "..jsonFile)
    local fileUtil = cc.FileUtils:getInstance()
    local fullPath = fileUtil:fullPathForFilename(jsonFile)
    local jsonStr = fileUtil:getStringFromFile(fullPath)
    local jsonVal = json.decode(jsonStr)

print("test LoadCCSJSON ----  uiloader222222 "..jsonFile)
    return jsonVal
end

具体哪里变慢，还在查当中

#2

发觉应该是uilabel的BUG了

cc.ui.UILabel.new({text = options.text,
            size = options.fontSize,
            color = cc.c3b(options.textColorR, options.textColorG, options.textColorB)}))

难道传说中的 CCLabelTTF 有内存泄露的问题，我还要的quick 2.2.6 …

#3

找来原因了,原来是2.2.6的 cc.FileUtils:getInstance():addSearchPath 这个导致:



  for i=1,1000 do 
   cc.FileUtils:getInstance():addSearchPath("res/")
    cc.FileUtils:getInstance():addSearchPath("res/common/")
  end 

cc.uiloader:load(jsonFile)

调用多次就会导致uiloader load 渲染非常的慢

验证3.3已经没有这BUG了
