This sort of question comes up every couple of weeks. You did not use
+alloc to create the string, so you do NOT need to release it. If you
try to release it, the app will crash. Any of these are correct:
NSString w = [NSString stringWithFormat:@"something %i", x];
// Do stuff
NSString w = [[NSString alloc] initWithFormat:@"something %i", x];
// Do stuff
[w release];
NSString w = [NSString stringWithFormat:@"something %i", x];
[w retain];
// Do stuff
[w release];
BUT NOT:
NSString w = [NSString stringWithFormat:@"something %i", x];
// Do stuff
[w release]; // Will crash here

If I call NSString w = [NSString stringWithFormat:@"something %i", x];
Am I now suppose to call retain on w?
When I'm done I know I'm suppose to release w.
