Answer 1

Put this into your NSManagedObject subclass:

+ (void)initialize
{
    if (self != [EntityManagedObjectSubClass class]) return;
    NSManagedObjectModel *managedObjectModel = [NSManagedObjectModel mergedModelFromBundles:nil];
    NSEntityDescription *entityDescription = [managedObjectModel entitiesByName][@"entityName"];
    NSFetchedPropertyDescription *fetchedPropertyDescription = [entityDescription propertiesByName][@"fetchedPropertyName"];
    NSFetchRequest *fetchRequest = [fetchedPropertyDescription fetchRequest];
    NSSortDescriptor *sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"sortDescriptorKey" ascending:YES];
    [fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]];
}

Replace EntityManagedObjectSubClass, entityName, fetchedPropertyName and sortDescriptorKey with your own stuff.
