lazy var fetchedResultsController: NSFetchedResultsController<StoryTemplatePack> =
{
let managedObjectContext = (UIApplication.shared.delegate as! AppDelegate).managedObjectContext
var frc: NSFetchedResultsController<StoryTemplatePack> = NSFetchedResultsController(fetchRequest: self.createFetchRequest(), managedObjectContext: managedObjectContext, sectionNameKeyPath: "sectionnum", cacheName: nil)
frc.delegate = self
return frc
}()
// FetchedResultsController: Create Request
func createFetchRequest() -> NSFetchRequest<StoryTemplatePack> {
let fetchRequest = NSFetchRequest<StoryTemplatePack>(entityName: "StoryTemplatePack")
fetchRequest.predicate = NSPredicate.init(format: "productidentifier != nil")
fetchRequest.sortDescriptors = [
NSSortDescriptor(key: "isfeatured", ascending: false),
NSSortDescriptor(key: "ispurchased", ascending: true),
NSSortDescriptor(key: "name", ascending: true)
]
return fetchRequest
}
The results should be sectioned according to the sectionnum property on StoryTemplatePack (which is a transient property calculated in code).
When I loop over the results of the NSFetchedResultsController it shows the correct section numbers and story pack names. There should be 3 sections, but the FRC is reporting only 1 section. The dumped results also show that I'm sorting the results correctly so that the section values are monotonically increasing.
---- dumping frc, num sections: 1
section 0 pack Incredible Journeys
section 0 pack Out for a Date
section 0 pack Party Time
section 1 pack Holiday Craziness
section 1 pack In the Office
section 1 pack On the Internets
section 1 pack On the Job
section 1 pack School Daze
section 1 pack Social Networking
section 1 pack TV Troubles
section 1 pack Technology Takes Over
section 2 pack Christmas Shenanigans
---- done dumping
self.fetchedResultsController.sections!.count is returning 1 when it should return 3.
What am I doing wrong or missing?
