NSZoneFree line is incorrect for a few reasons (one is your object
doesn't own the zone it was allocated from so it shouldn't attempt to
free that zone).
In dealloc you are responsible for releasing any objects your object
maintains a retain on and/or any memory your object allocated and
owns. You are not supposed free memory of your own object in dealloc.
Your object was sent a dealloc message by the runtime because the
runtime is about to destroy the object and the runtime wants you clean
up anything your object owns.
Even C++ you don't free the object itself in the destructor.
