iOS中OC字符串与C语言字符串相互转换

一、C字符串转OC字符串

const char *cString &＃61; "This is a C string";
//对象方法
NSString *ocString1 &＃61; [[NSString alloc] initWithUTF8String:cString];
NSString *ocString2 &＃61; [[NSString alloc] initWithCString:cString encoding:NSUTF8StringEncoding];
NSString *ocString3 &＃61; [[NSString alloc] initWithFormat:&＃64;"%s",cString];

//类方法
NSString *ocString4 &＃61; [NSString stringWithCString:cString encoding:NSUTF8StringEncoding];
NSString *ocString5 &＃61; [NSString stringWithUTF8String:cString];
NSString *ocString6 &＃61; [NSString stringWithFormat:&＃64;"%s",cString];

二、OC字符串转C字符串

NSString *ocString &＃61; &＃64;"This is a OC string";
//对象方法
const char *cString1 &＃61; [ocString cStringUsingEncoding:NSUTF8StringEncoding];
const char *cString2 &＃61; [ocString UTF8String];
