Search ios reminders without date

Question

I'm familiar with using the eventstore search predicates like predicateForIncompleteRemindersWithDueDateStarting:Ending:Calendars:

but I'm trying to figure out how I can search for any incomplete reminders that don't have any due date set. I've tried NSCompoundPredicate but eventstore won't fetch a predicate that's not created with its own predicate creation methods. Any ideas?

Edit: As per the documentation, passing nil for both start and end dates results in all reminders, not solely reminders without dueDates.

EDIT

You can try to filter all incomplete reminders to get only without due date:

[store fetchRemindersMatchingPredicate:predicate
                            completion:^(NSArray *reminders)
     {
         NSArray *myReminders = [reminders filteredArrayUsingPredicate:
                                 [NSPredicate predicateWithFormat:@"dueDateComponents = nil"]];
         NSLog(@"%@", myReminders);
     }];

Documentation for predicateForIncompleteRemindersWithDueDateStarting:ending:calendars::

Discussion
Pass nil for startDate to find all reminders due before endDate. Similarly, pass nil for both startDate and endDate to get all incomplete reminders in the specified calendars.
