[11011001]

I would like to be able to initialize an NSPersistentDocument only when a new Untitled Document is created. In other words I would like to populate it's model with a few objects, but I don't want a newly opened document to be repopulated with these items. Does anyone have some ideas how I could go about doing this, preferably within the NSPersistentDocument subclass.

I have tried checking the managedObjectContext within init to see if those items are already there, but unfortunately it seems that the managedObjectContext hasn't been filled at this point.

NSPersistentDocument uses a specific method to do exactly this. It's an initialiser that is only called for new documents, and not for opening existing documents. See the CoreData NSPersistentDocument tutorial on Apples developer documentation pages for the details:
