HelloWorld.cpp 中 init()  函数中添加

CCSVParse* csvFile = new CCSVParse();
        csvFile->openFile("Book1.csv");
        for (int i=; i<csvFile->getCols(); ++i)
        {
            string strLine = "";
            for(int j=; j<csvFile->getRows(); ++j)
            {
                strLine += csvFile->getData(i,j);
                strLine += ",";
            }
            CCLabelTTF* pLab = CCLabelTTF::create(strLine.c_str(),"Arial",);
            pLab->setPosition(ccp(size.width/,size.height--i*));
            this->addChild(pLab,);
        }

Book1.csv 内容  注意将文件保存为UTF-8格式的（否则中文显示乱码）
