I have a core data app where I don't necessarily know when managed objects go away, as in: become faults, will be deleted etc.. I also need to add the observer to the managed object in awakeFromFetch, but that gets not only called upon opening an existing object, but also later on when fetches are executed.
I take it the answer to my question is no? As in: No, an object can not ask another if it's being observe by it? For now I have solved the problem by setting a flag on the managed object when it registers itself for observation.
