Initializing an array with objects when iOS app loads
===

I've been going through some iOS examples online I came across an app where the app initializes an array and then add objects to it when the iOS app launches.  Initializing works when I use `(void) viewDidLoad`  in my implementation file but initialing the array does not work when I use 

`- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil`

Can someone tell me why is that so?  Thanks!


Here is the code - 


(void) viewDidLoad
{
    if (self) {
        questions = [[NSMutableArray alloc] init];
        answers = [[NSMutableArray alloc] init];
        
        // Add objects to the arrays
        [questions addObject:@"What is 1+1"];
        [answers addObject:@"2"];

        [questions addObject:@"What is 2+2"];
        [answers addObject:@"4"];

        [questions addObject:@"What is 3+3"];
        [answers addObject:@"6"];
    }
    
    [super viewDidLoad];


and the code for 


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        
        // Create two arrays and make the pointers point to them
        questions = [NSMutableArray array];
        answers = [NSMutableArray array];
        
        // Add questions and answers to the arrays
        [questions addObject:@"From what is cognac made?"];
        [answers addObject:@"Grapes"];
        
        [questions addObject:@"What is 7 + 7?"];
        [answers addObject:@"14"];
        
        [questions addObject:@"What is the capital of Vermont?"];
        [answers addObject:@"Montpelier"];
        
    }
    return self;
}
