Get changed objects in NSManagedObjectContext before saving?

Question

I want to save changes on backend also, so I want to subclass NSManagedContext, override save method and loop al the changed object and call the appropriate RESTFull service. But how can I get the changed / inserted objects?

UPDATE:

I found that with setIncludesPendingChanges I can get the changed objects, but I still need to set the entity name for NSFetchRequest. But I want to fetch all different type of entites. How?

I found answer here: http://stackoverflow.com/questions/3235498/coredata-fetching-an-object-from-an-unsaved-context — János, Apr 15 '14 at 19:05
Please write that as an answer, then accept it, so that your question doesn't show up as unanswered. — Hal Mueller, Apr 15 '14 at 22:47

I found here a more appropriate solution based on NSManagedObjectContextDidSaveNotification: How to sync CoreData and a REST web service asynchronously and the same time properly propagate any REST errors into the UI
