I'm learning Core Data to work out how the fetch button in IB can be
set to a particular fetch request.
I have set up three fetch requests with predicates for one of my
entities. And when I go to IB, I see that the fetch button has a
target-action connection to the NSArrayController object. But how do
you use the button? Clicking on it doesn't do anything. And I can't
figure out where I would specify which fetchRequest to associate with
the button. Since the array controller is a canned "freeze-dried"
object, where would I put code in this case?
Sorry if this is obvious.
Daniel
