//int 轉 CCstring

int num＝5;
 CCString* ns=CCString::createWithFormat("%d",num);
 
 //CCstring 轉 int
int px = ns->intValue();//將CCString 轉換為int的方法,轉成float類型有 floatValue()
//======================================
 
//CCString 轉    char
const char *string= ns->getCString();
 
//char 轉    CCString
CString.Format(”%s”,char *)//char 轉cstring 
 CCString* ns=CCString::createWithFormat("%s",char *);
//======================================
 
//string 轉  char
const char *string=std::string("STRING").c_str();
char 轉 string
string s(char *);
//======================================
 
//string  轉 int
std::string s("1234");
int n = std::atoi(s.c_str());//函數原型int atoi(const char *);
 
//int 轉 string
int a=3;

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

string s=ns->m_sString;

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

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

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

CCString 轉 string

std::string s= ns->m_sString;//ns是一個CCString*類型

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

//char 轉  int

 char *buf = "1122";

 int n = std::atoi(buf);

//int 轉 char

int a=3;

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

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

cocos2d-x類型轉換(CCstring int string char UTF-8互轉)
