Hi guys,

I have an object NetworkMember that has no attributes but is defined by its relationships Person, Network, Level and Role. In my app, I've found all the four relationships, but I want to make sure not to double-register my NetworkMember, thus I'd like to search for this NSManagedObject before instantiating it.

How should I write a query that queries for an NSManagedObject just consisting of relationships?

Cheers

Nik
