Compare strings on iPhone fails?

Question

Hi,

I'm trying to compare two strings with each other on the iphone, but the IF statement is always false. Here's my code:

NSLog([[UIDevice currentDevice]uniqueIdentifier]);
if ([[[UIDevice currentDevice]uniqueIdentifier] compare:[[NSUserDefaults standardUserDefaults] valueForKey:@"id"]] == NSOrderedSame) {
    //OK
    NSLog("Do stuff if equal");
} else {
    // Not OK
    NSLog("Do stuff if not equal");
}

The output is always

*** UDID *** (<- my device's UDID)
Do stuff if not equal

What am I doing wrong?

Thanks! Yvan

Try using stringForKey: instead of valueForKey:, and isEqualToString: instead of compare: ... == NSOrderedSame.
