How can I append objects to an NSMutableArray?

Question

I have two arrays and I would like to append one to the end of the other. How can I go about doing this?

self.itemsCopy = [self.items mutableCopy];

Will copy the array, but I would like to append self.items.

Isn't this just an extension of your original question? stackoverflow.com/questions/2976910/… — Joshua Nozzi

Joshua Nozzi: Nothing wrong with that. It is a separate question, regardless of its origins. — Peter Hosey

Assuming itemsCopy is an NSMutableArray that has already been created, you can do:

[self.itemsCopy addObjectsFromArray:self.items];

Check out the docs for NSMutableArray:

addObjectsFromArray:

Adds the objects contained in another given array to the end of the receiver’s content.

(This won't be a deep copy, however)
