Member Since: Jun 02, 2010 Posts: 6	06-21-2010, 02:05 PM I have two NSArrayControllers that manage two different entities (core data), when I add an object to the array I want it to check for duplicates and if this is true merge the properties of the objects. How can I do this? Thank you very much Andres Gonzalez
