NSDictionary will use almost any object as a key:

Yes, but he said he wants to use a view as the key. Views are not
immutable, and do copy themselves in response to -copy. Having a
dictionary whose key objects are copies of your live views is not very
useful. (Especially since the copied view will have a different
hashcode from the original one, so you can't even look it up using the
original view anymore...)
