If you require a mutability guarantee, it is always safe to create your own copy after the fact. Best case you were returned an immutable object and it is just a retain, worst case it was a mutable object that wouldn't have been modified anyway. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
