Re: Do I Need Multiple NSArrayControllers For This?

I have a Core Data entity that has a date and relationship. I want to create a label like.

"25 Foos (12 New)"

A Foo is active if it its relationship is null and it is new if its date is within the startDate and endDate specified by the user.

My intuition is that this does require two NSArrayControllers each with a filter predicate binding to get the desired array of Foos, but I wanted to see if there was anything I hadn't considered.

You might want a value transformer on the arrangedObjects of the array controller: one that just returns the count, and one that returns the count as filtered by a predicate.
