title: Shared Objects in Cocoa
body: <p>I'm working with CoreData in Cocoa (not document-based).
  My problem is, that I want to access the SAME NSArrayController from different NIBs.
  But every NIB has an own instance of this NSArrayController.</p>
  
  <p>My question is now how I could generate sharedObjects (like the NSUserDefaultsController).
  It would help me a lot. Thanks for your answers. =)</p>
