The *can* be done depends upon the requirement...
Instead of releasing and recreating already created object ,
one can re-use already created object(improves the performance, at least in
my application).
This concept is used in the "shared object" approach.
If you know how to implement entire dealloc method, you need not call super
dealloc :-)

Lots of things *can* be done. The question is, *should* it?
(Example: you *can* write a dealloc method without calling super dealloc.
But don't!)
I think what I'd like to hear the OP focus on is *why* he thinks he might
need to do this. Since an instance "re-initialized back to its initial
state" would be effectively the same as a completely new instance, why not
use a completely new instance? What do you think "re-initialization" would
get you? m.
