When you say I can manage the outlets any way I like this is
wrong. They are managed for me. I want them to not be retained.
I don't have that option.
Now that I understand this I can live with it. But it still makes
no sense to me.

That's not what the documentation says and it's not my experience
either. The documentation says (section titled NIB Object Retention)
that each object in the NIB file is created with a retain count of 1
and then autoreleased. Then they are hooked up using
setValue:forKey: which uses the setter method if it exists. It also
explicitly tells you that if you don't retain the array of top-level
objects you're going to lose them.
So if you have an outlet which is assign, and the setter method is
correct, the object will be created with retain count of 1,
autoreleased, then the setter method will be called and assign it
(no retain) and you do not have to release it. Why do you think that
you do?
I've done this, I have this exact patten in some of my iPhone code,
I have a delegate property which is assign and it is assigned and it
goes away when it's supposed to go away.
OK. The reason I believe that is because I fixed a massive memory
leak a couple days ago that I tracked down to this issue. I built a
simple test application that demonstrates that outlets that have no
properties or have assign properties are retained anyway and must be
released.
Here's my test project:
http://bellsouthpwp2.net/b/r/brians99/projects/TestPropertiesAndOutlets.zip
There are three labels that are outlets. One has a retain property,
one an assign property, and the third no property. Unless they are
released they are never dealloced. All three act the same.
