(objective C) Can't figure out this simple array problem

I tried a ton of different things and it just won't work, i've tried just alloc and init, addObject, etc.

Heres what i did:

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];

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

@end

Hi Martin,

You're close. self refers to the actual object that you are using, in this case, UIViewController. So, you need to specify the property you need to access. It should look like this:

// shoppingList is a property of your ViewController (self)
self.shoppingList = [[NSArray alloc]initWithObjects: @"toothpaste",@"bread",@"eggs",nil];

Regards!
