Build a Simple iPhone App quiz

Let's add a few items to our grocery list. Switch to the implementation file and in the viewDidLoad method, initialize the shoppingList array to the following items: 'toothpaste', 'bread' and 'eggs'. I am getting a error stating that I am not adding all of the elements... Below is my code.

ViewController.h 
#import "UIViewController.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) NSString *shoppingCart;
@property (strong, nonatomic) NSArray *shoppingList;
@end
ViewController.m 
#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below!
    NSArray *shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];
}

@end

I have the exact same thing. I think there is a bug in their code checker. Please advise.

Hey Eric,

I figured it out. It's similar the the facts array from the video but slightly different. This time, you are initializing the object's shoppingList property, not just a temporary array like the facts array was. So you need to do it this way:

self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];

Hope this helps!
