As I said, you shouldn't, you should use an object controller as an
intermediate.
an object controller knows when the document needs to get/abandon
changes, and is informed when the UI items change focus, which can
cause changes to be committed or abandoned.
always use an object controller. always always always.
1) How do I link an NSObjectController to the shared application, in a
nib whose File's Owner isn't the application?
you can either connect the content outlet, or bind it to
programmatically.
2) What exact difference does it make in a non-document-based
application?
none. it was just an easy example. File's Owner is always a proxy
for the owner of the nib.
