But note that storing a pointer value in a string like this is still problematic under garbage collection. It will not act like a strong reference, so the object may be destroyed while still being "referenced" by the string. But it will not act like a zeroing weak reference either, so you'll still be able to get the pointer even after it's been destroyed, which will (probably) lead to a crash. An NSMapTable can be configured to give either reasonable behavior (strong or zeroing weak reference) so use that instead.
