Can't query the reminders in a calendar from ekstore

Question

I'm trying to get a list of reminders from a calendar but I'm keep getting an error. I can do a similar thing with calendar events but when i try and amend it for reminders i run into problems.
This code fails on the first line to do with EKEntityMaskReminder

   _store = [[EKEventStore alloc] initWithAccessToEntityTypes:EKEntityMaskReminder];
        EKCalendar *calendar = [_store calendarWithIdentifier:[self.detailItem valueForKey:@"cal_id"]];
    NSArray *calendarArray = [NSArray arrayWithObject:calendar];
    NSPredicate *predicate = [_store predicateForRemindersInCalendars:calendarArray];
    _eventsList = [_store fetchRemindersMatchingPredicate:predicate completion:nil];

The error message is:

-[EKEventStore initWithAccessToEntityTypes:]: unrecognized selector sent to instance 0x157660

If i change the store thus:

_store = [[EKEventStore alloc] init];

then it fails with:

'-[EKEventStore predicateForRemindersInCalendars:]: unrecognized selector sent to instance 0x165c20'

I am able to create a reminder if i set the store as:

_store = [[EKEventStore alloc] init];

and it shows in the reminders app.

Does anyone know why i can't query these reminders?

Answer 1

Both of the selectors you're getting errors on have availability starting with iOS 6. If you're trying to run your program against something other than the beta OS/libraries, it's going to fail.

(It's extremely odd that initWithAccessToEntityTypes is recommended in iOS 5.1 documentation, though without a method description.)
