What is the above method doing? I hope it is not retaining or releasing the
reference it is keeping in it's dealloc method. That will cause a crash when
next time this obj is accessed after releasing your *baddie object*.
Normally to maintain a weak reference delegate pattern is used, where
delegate is never retained or released.
If you are doing that right, see if you get a crash log/stack trace or any
logs in sys-console.
