这里写一个工具类——XMLParser,用来解决游戏中出现的中文乱码问题。
主要是把游戏中要使用到的文字存储在XML文件中,通过加载这个文件,并且访问name节点,来获取相对应的中文。
XMLParser.h如下

XMLParser的使用:
XMLParser *pXmlParser = XMLParser::parseWithFile("tujiLayer.xml");
String *mz = pXmlParser->getString("muzhuang");
m_pMZLabel = LabelTTF::create(mz->getCString(),"",30); // 注意此处的getCString()
