Convert NSMutableArray to a NSSet with the same order

Question

How can I do that programatically?

I am told that this is the way to do it but the NSSet has a different order.

NSSet *set = [NSSet setWithArray:theArray];

Any idea?

Thanks in advance.

Answer 1

If you want order, you'll have to use an NSOrderedSet.

NSOrderedSet *set = [NSOrderedSet orderedSetWithArray:theArray];

Answer 2

If you care about the order, you probably do not want to use an NSSet.
