Hi, I didn't see any followups to your post. I'm not really
understanding the problem though. Would  you post some code showing how
you are alloc-ing, init-ing and retain-ing the object? Also seeing the
code for it's -init method and dealloc method would be helpful.

If you are calling -alloc yourself, you are responsible for releasing
or autoreleasing the object. What are you doing with the object after
alloc-ing it? Are you autoreleasing or releasing it before using or
returning the object?

All of my memory related crashes in ObjC have been due to me releasing
an object when it should have been autoreleased, or not retaining an
object that was autoreleased when I received it.
