Unable to solve Challenge Task

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'.

What is wrong with my code,

How do i initialise an array separate from the creation steps? Thanks a ton.

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!
    self.shoppingList.text =  [ shoppingList initWithObjects : @"toothpaste",@"bread", @"egg", nil] ;



}

@end

Two things: NSArray doesn't have the text property, and you're using the wrong method for initializing the array. Try using the NSArray arrayWithObjects method to initialize and fill the array. It looks like this:

NSArray *array = [NSArray arrayWithObjects:object1, object2,nil];
