Hi there, I've been going through Hillegass' "Cocoa Programming for Mac OS X" and maybe I'm impatient and this is answered later than ch. 13, but there seems to be a fairly simple question that he has not addressed:
I understand how to use Core Data with an Array Controller to create and edit objects through a TableView, but what about when it comes to using that data?
For example, if I want one button to scan the current members, and add the ones with trait X to a second array controller, displayed on a second Table View, what calls would I be performing?
Is this a job for an app controller, or the MyDocument class? Perhaps I could add an IBAction method to the Controller, that makes calls to the Array Controllers? Is this the appropriate approach to manipulating Core Data entities?
