Hi,
I think you might be making this harder than it needs to be because you
are expecting the File's Owner of application's main nib file (usually
MainMenu.nib) to require a lot of wiring up. Generally, it doesn't.
File's Owner is used to link object from one nib to another. Since your
main nib is loaded at application start, and is generally not receiving
messages from objects in other nibs, its File's Owner does not normally
need to do much.
File's Owner becomes important when you have more than 1 nib. You will
generally give it connections to the objects in its own nib that need to
be controlled from outside. It should also have the signatures of any
delegate methods, etc. that are needed for the nib objects to receive
their messages from the outside objects.
Now, when you need the objects in your second nib, you will load the nib
and pass in as the owner: an already instantiated object. This object
will need to have all of the same types of outlets as the second nib's
File's Owner, and it should implement whatever methods the File's Owner
has listed.
However, this object will not actually be wired up to the File's Owner
object in IB. It will become the File's Owner and be wired up
programatically when the nib is loaded with this instance object as the
owner. It will take over the role of File's Owner and be assigned all of
the connections of the File's Owner for the loaded nib.
You should view the File's Owner object in IB as a place holder or a
template. If you consider it a template, then it describes what the
class that will take its place at run should do.
I hope the above explanation is helpful. It is my understanding of the
how/why of File's Owner. It may be slightly off conceptually, but
practically this understanding has served me well.
Cheers,
Jason
