Remove reminders using NSPredicate iOS

Question

I am trying to remove reminder using NSPredicates but they are not getting removed. My code is:

NSPredicate *predicate = [eventStore  predicateForIncompleteRemindersWithDueDateStarting:[datepicker1 date] ending:[datepicker2 date] calendars:nil]
     [eventStore fetchRemindersMatchingPredicate:predicate completion:^(NSArray *reminders)
     {
         for (EKReminder *reminder  in reminders) {
             [eventStore removeReminder:reminder commit:YES error:nil];
        } }];

Answer 1

You should also specify the calendars parameters as

EKEventStore *eventStore = [[EKEventStore alloc] init] ;
NSArray *calendarArray = [NSArray arrayWithObject:[eventStore defaultCalendarForNewEvents]];
NSPredicate *predicate = [eventStore  predicateForIncompleteRemindersWithDueDateStarting:[datepicker1 date] ending:[datepicker2 date] calendars:calendarArray]
     [eventStore fetchRemindersMatchingPredicate:predicate completion:^(NSArray *reminders)
     {
         for (EKReminder *reminder  in reminders) {
             [eventStore removeReminder:reminder commit:YES error:nil];
        } 
}];

I hope this should work.
