Can I use NSFetchedResultsController with this library?
I think it can be useful, specially when I add an element to my data model from another part of the program.
I ask this question because I'm not sure if NSFetchedResultsController can be only used with UITableViewController.
NSFetchedResultsController is not tied to UITableViewController (or any other type of controller) — it's a fairly generic data source. I am using it in one of my apps to back a GMGridView instance, so it's definitely possible.
Super easy to implement.
