//int 转 CCstring

int num＝5;
 CCString* ns=CCString::createWithFormat("%d",num);
 
 //CCstring 转 int
int px = ns->intValue();//将CCString 转换为int的方法,转成float类型有 floatValue()
//======================================
 
//CCString 转    char
const char *string= ns->getCString();
 
//char 转    CCString
CString.Format(”%s”,char *)//char 转cstring 
 CCString* ns=CCString::createWithFormat("%s",char *);
//======================================
 
//string 转  char
const char *string=std::string("STRING").c_str();
char 转 string
string s(char *);
//======================================
 
//string  转 int
std::string s("1234");
int n = std::atoi(s.c_str());//函数原型int atoi(const char *);
 
//int 转 string
int a=3;

CCString* ns=CCString::createWithFormat("%d",a);

string s=ns->m_sString;

//======================================

//string 转 CCString
std::string str = "123";

CCString* ns=CCString::createWithFormat("%s",str.c_str());

CCString 转 string

std::string s= ns->m_sString;//ns是一个CCString*类型

//======================================

//char 转  int

 char *buf = "1122";

 int n = std::atoi(buf);

//int 转 char

int a=3;

CCString* ns=CCString::createWithFormat("%d",a);

const char* s=ns->getCString();
