If-Statement for String/Int

Question

my if clause always runs into the else statement? Whats the fault?

        NSLog([[category objectForKey:@"id"] stringValue]); // Traces 15
        if ([[category objectForKey:@"id"] stringValue] == "15") {
            result.isExternal = YES;
        } else {
            result.isExternal = NO;
        }

thanks for helping

what is the type of the object held by your dictionary? – Brandon Bodnar Feb 13 '10 at 21:16 — Brandon Bodnar, Feb 13 '10 at 21:16

You should change

[[category objectForKey:@"id"] stringValue]

to

[[[category objectForKey:@"id"] stringValue] isEqualToString:@"15"]

And as for comparing that stringValue how you are, you need to do == @"15" as "15" isn't a string unless an @ is infront.

Thanks, but I still run into the else statement. – fabian Feb 13 '10 at 21:11
Then try comparing the `intValue` like so: `[[[category objectForKey:@"id"] intValue] isEqualToNumber:[NSNumber numberWithInt:15]]` – Garrett Feb 13 '10 at 21:14
`intValue` returns an `int`, which means you can do `[... intValue] == 15` – Dave DeLong Feb 13 '10 at 21:21
Gah, was just editing my original answer, forgot you should do what you said. Thanks! – Garrett Feb 13 '10 at 21:47

You should use isEqualToString Is it necessary to assign a string to a variable before comparing it to another?

Your "if" statement is comparing two C strings with "==". You should use strcmp for that. If your function returns an objective C string, you should use @"15", and the correct comparison function.
