1、继承自CCObject
class CC_DLL CCString : public CCObject2、如果通过create创建，会加入自动释放池，通过new创建则不会，所以使用时要记得retain，然后释放时 使用release。
CCString* CCString::create(const std::string& str){ CCString* pRet = new CCString(str); pRet->autorelease(); return pRet;}-->>CCString::CCString(const std::string& str) :m_sString(str){} 3、通过字节数组CCString* CCString::createWithData(const unsigned char* pData, unsigned long nLen){ CCString* pRet = NULL; if (pData != NULL) { char* pStr = (char*)malloc(nLen+1); if (pStr != NULL) { pStr[nLen] = '\0'; if (nLen > 0) { memcpy(pStr, pData, nLen); } pRet = CCString::create(pStr); free(pStr); } } return pRet;}4、格式化创建CCString::createWithFormat("%s%02d.png",c,1);CCString* CCString::createWithFormat(const char* format, ...){ CCString* pRet = CCString::create(""); va_list ap; va_start(ap, format); pRet->initWithFormatAndValist(format, ap); va_end(ap); return pRet;}5、读取文件创建CCString* CCString::createWithContentsOfFile(const char* pszFileName){ unsigned long size = 0; unsigned char* pData = 0; CCString* pRet = NULL; pData = CCFileUtils::sharedFileUtils()->getFileData(pszFileName, "rb", &size); pRet = CCString::createWithData(pData, size); CC_SAFE_DELETE_ARRAY(pData); return pRet;}6、获取C类型的字符const char* CCString::getCString() const{ return m_sString.c_str();}7、获取长度unsigned int CCString::length() const{ return m_sString.length();}8、相等比较bool CCString::isEqual(const CCObject* pObject){ bool bRet = false; const CCString* pStr = dynamic_cast (pObject); if (pStr != NULL) { if (0 == m_sString.compare(pStr->m_sString)) { bRet = true; } } return bRet;}9、析构CCString::~CCString(){ m_sString.clear();} 转载地址：http://stsmi.baihongyu.com/
