请问cocos2d quick-3.3里面 为何有句代码被注释掉了

Studio
#1 
请把代码粘贴在这里


```

Widget* GUIReader::widgetFromJsonFile(const char *fileName)
{
    std::string jsonpath;
    rapidjson::Document jsonDict;
    jsonpath = fileName;
//    jsonpath = CCFileUtils::getInstance()->fullPathForFilename(fileName);
    size_t pos = jsonpath.find_last_of('/');
    m_strFilePath = jsonpath.substr(0,pos+1);
    std::string contentStr = FileUtils::getInstance()->getStringFromFile(jsonpath);
    jsonDict.Parse<0>(contentStr.c_str());
    if (jsonDict.HasParseError())
    {
        CCLOG("GetParseError %s\n",jsonDict.GetParseError());
    }
    Widget* widget = nullptr;
    const char* fileVersion = DICTOOL->getStringValue_json(jsonDict, "version");
    WidgetPropertiesReader * pReader = nullptr;
    if (fileVersion)
    {
        int versionInteger = getVersionInteger(fileVersion);
        if (versionInteger < 250)
        {
            pReader = new (std::nothrow) WidgetPropertiesReader0250();
            widget = pReader->createWidget(jsonDict, m_strFilePath.c_str(), fileName);
        }
        else
        {
            pReader = new (std::nothrow) WidgetPropertiesReader0300();
            widget = pReader->createWidget(jsonDict, m_strFilePath.c_str(), fileName);
        }
    }
    else
    {
        pReader = new (std::nothrow) WidgetPropertiesReader0250();
        widget = pReader->createWidget(jsonDict, m_strFilePath.c_str(), fileName);
    }
    
    CC_SAFE_DELETE(pReader);
    return widget;
}

上面还有一句“jsonfile = filename”，
