Question

Newbie here (to C, objective-C, and iOS)…

For this code in my AppDelegate.m, why is the freshly initialized array empty? Looks to me like I give it some values. Clue1 etc are are series of UILabels and there are no issues noted by Xcode. I’ve been through SO quite a bit and this seems to be the way to do it. Xcode 4.2. Thanks!

- (id)init {       
    self = [super init];
    if(self) {           
        // Make arrays containing the objects: this is the objective-C way!
       self.clueLabs = [[NSMutableArray alloc] initWithObjects: Clue1, Clue2, Clue3, nil];
    }   
    NSLog(@"%@", [clueLabs description]);
    if (!clueLabs || ![clueLabs count]) { // these 2 do m/l the same thing
        NSLog(@"clueLabs is empty!");
    }       
    return self; 
}

Answer 1

Check if Clue1, Clue2 Clue3 are not nils.
