You're almost there, you just have some simple errors.
You've assigned
shoppingList
as a local variable within theviewDidLoad
method, theNSArray
instance should be assigned to the class property insteadYou're trying to assign an object to
self.shoppingList.text
which won't work asshoppingList
is of the typeNSArray
The
objectAtIndex
method only accepts a single argument which is an integer, for this you only need the number 2
self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil]
self.shoppingCart = [self.shoppingList objectAtIndex:2];
Happy coding!
