[SOLVED] Can't pass challenge task 2

I write some code as follows:

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

But it said:Make sure you're adding all three items to the shopping list.

Can't figure out what's the problem

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

Just figure out by my self... It should write as follows:

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

Glad you were able to get it figured out! :)
