Answer 1

What you get is not the object ID, but the URI. The object ID is a part of the URI. You can ask the persistent store coordinator for the object ID with - managedObjectIDForURIRepresentation:. Having the object ID you can get the object from the context using for example -objectWithID:. But please look to the documentation, of this methods for some reasons.
