Seems to work regardless of the mode. Is there anything to read up
on this - couldn't find anything specifically on these modes.
There's two points to consider:
1. If you're trying to create Core Data objects, you *must* use
entity mode, so that it uses the correct initializer for a
NSManagedObject subclass. However, it's certainly possible that
NSObjectController in Class mode checks to see if it's really
creating a managed object and modifies its own behavior accordingly.
2. In various ways, some NSController and NSObjectController
behaviors are just stubs for consistency with important behavior in
NSArrayController. In that case it *does* matter which mode you
specify.
This is discussed briefly near the start of:
http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CoreData/Articles/cdBindings.html#/
/apple_ref/doc/uid/TP40004194
It's brief because there isn't much to say. If you're dealing with
Core Data, specify an entity name and a managed object context.
Otherwise specify a class and no managed object context.
