your can use bytes method of NSData;

NSUInteger len = [yourData length];
Byte *byteData = (Byte*)malloc(len);
memcpy(byteData, [yourData bytes], len);

If your byte is null terminated you can use

NSString *content = [NSString stringWithUTF8String:[yourData bytes]];

and if not

NSString *content = [[NSString alloc]  initWithBytes:[yourData bytes]
          length:[yourData length] encoding: NSUTF8StringEncoding];
