How to store NSArray in NSDictionary?

Question

I'm trying to teach myself, but struggling with how to store something like NSArray inside an NSDictionary.

Suppose you had an NSDictionary for recipes:

Let's say in NSDictionary there were such keys as:

Spaghetti, Fettusin Alfredo, Grilled Chicken Salad

And in NSDictionary was NSArray, which was just a list of ingredients.

I assume that the equivalent PHP code would be something like this:

$['Spaghetti'] = array('Spaghetti Pasta', 'Spaghetti Sauce', 'Meatballs');
$['Fettucine Alfredo'] = array('Fettucine Pasta', 'Alfredo Sauce');
$['Grilled Chicken Salad'] = array('Lettuce', 'Grilled Chicken', 'Croutons');

I am struggling with how to add NSArray to NSDictionary. Then what if I wanted to delete an element or add an element to an array? How is it extracted and removed or added?

Answer 1

NSDictionary* dict = [NSDictionary dictionaryWithObjectsAndKeys:
  [NSArray arrayWithObjects:@"Spaghetti Pasta", @"Tomato Sauce", nil], @"Spaghetti",
  [NSArray arrayWithObjects:@"Fettuccine Pasta", @"Alfredo Sauce", nil], @"Fettuccine Alfredo",
  [NSArray arrayWithObjects:@"Lettuce", @"Grilled Chicken", @"Croutons", nil], @"Grilled Chicken Salad",
  nil];
