I have a source object, sourceObj, with a to-many relationship. Say the relationship key is "targets" . I obtain the related objects by invoking sourceObj.targets() where the method targets() returns an NSArray as a cover for a call to storedValueForKey( "targets" ).
I now invoke:
/* Assume editingContext exists and all EOs are in it */
editingContext.deleteObject( aSpecificTargetObject )

You also need to do a removeObjectFromBothSidesOfRelationshipWithKey. If the sourceObj "owns" the deleted object that's all you have to do.
