Re: Programatically bind NSArrayController to NSManagedObjectContext?

And again, why is this any different to any other binding? It's just a key path.
In this case, though, if you're not binding through any other object, why not just set it directly (setManagedObjectContext:)?

Ah, very good. When I saw that it was called a "binding" in Interface Buildero I went into the Cocoa Bindings Reference looking for a binding. In this case, there is none, and indeed as you suggested the only way do it is by setting directly:


[arrayController setManagedObjectContext:xxx] ;
[arrayController setEntityName:yyy] ;
[arrayController prepareContent] ;

NSManagedObjectContext is not listed in the Cocoa Bindings Reference [1]. Is this really a "binding", or is it something else? The documentation for binding NSArrayController 'managedObjectContext' in [1] calls it "registered with".

It's not clear what this means.
Bindings are bindings.

Well, I would say that the code I entered above is not a binding because it does not, and could not, invoke bind:toObject:withKeyPath:options. However, the effect is indeed the same and I guess it doesn't matter what we call it.


Thanks, mmalc. My programatically-instantiated array controller is working with my moc now.
