Objective C stringWithFormat if statement

Question

I'm pretty new to this - I'm trying to compare a NSString stringWithFormat with some text. It works fine with stringWithString. I can't work out why it doesn't work with stringWithFormat? Many thanks for any help anyone can offer!

    NSString *theQuestion = [NSString stringWithFormat:@"The same thing"];
if (theQuestion == @"The same thing"){
        NSLog(@"stringWithFormat is the same as the given text");
    }else{
NSLog(@"stringWithFormat is NOT the same as the given text");
        NSLog(@"but theQuestion is:\"%@\"", theQuestion);
    }

== is a reference equal. to do a string compare it has to be the

if([theQuestion isEqualToString:@"The same thing"]){

}

It should be:

NSString *theQuestion = [NSString stringWithFormat:@"%@",@"The same thing"];

Also, Use `isEqualToString method`, not `==`: `if ([theQuestion isEqualToString:@"The same thing"]){` – MByD Aug 13 '11 at 18:02
`StringWithFormat: @"The same thing"` should be fine, although useless. I would use `stringWithString: @"The same thing"` instead. – Rudy Velthuis Aug 13 '11 at 18:13
…Or just `NSString *theQuestion = @"The same thing";`. – Wevah Aug 13 '11 at 18:23
