#define MSG_STR(x) @"" #x

will turn any x into an NSString constant e.g.

NSLog(@"%@", MSG_STR(a + b));

will give output similar to

2011-08-25 11:00:10 +0100 otest[89432:707] a + b

It works using the fact that the compiler coalesces syntactically adjacent string constants.

Not totally sure I understand what you want to achieve, but could you not just use the following:

#define DES_STR(message) [NSString stringWithFormat:@"ready to get:\"%@\".Find out how here.", message];

NSString *shareFinalText = DES_STR(shareWord);
