第一方法
SystemHeader.h

#define SaveStringToXML CCUserDefault::sharedUserDefault()->setStringForKey
 
#define SaveIntegerToXML CCUserDefault::sharedUserDefault()->setIntegerForKey
 
#define SaveBooleanToXML CCUserDefault::sharedUserDefault()->setBoolForKey
 
#define LoadStringFromXML CCUserDefault::sharedUserDefault()->getStringForKey
 
#define LoadIntegerFromXML CCUserDefault::sharedUserDefault()->getIntegerForKey
 
#define LoadBooleanFromXML CCUserDefault::sharedUserDefault()->getBoolForKey

实用例子

SaveStringToXML("name","dengao");
CCUserDefault::sharedUserDefault()->flush();//写了东西要提交 
std::string name = LoadStringFromXML("name");
log("name: %s ",name.c_str());

数据保存的地方

log("%s",FileUtils::getInstance()->getWritablePath().c_str()); 

第二种方法

CCUserDefault::sharedUserDefault()->setStringForKey("name","dengao");
 
std::string name = CCUserDefault::sharedUserDefault()->getStringForKey("name");
log("name: %s ",name.c_str());
