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)
