ios - 对日历守护程序的谓词调用失败 : Error Domain=EKCADErrorDomain Code=1013

Question

对日历守护程序的谓词调用失败:错误域=EKCADErrorDomain 代码=1013“操作无法完成。(EKCADErrorDomain 错误 1013。)”

我正在尝试从默认应用中获取提醒。

if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
        // need user permission for iOS 6 and later
        [eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
            if (granted) {
                //---- codes here when user allow your app to access theirs' calendar.
                [self performCalendarActivity:eventStore];
            }
            else {
                //----- codes here when user NOT allow your app to access the calendar.
            }
        }];
    }

----获取日期的提醒------

-(void)performCalendarActivity:(EKEventStore*)evtStore
{
    self.eventsList = [[NSMutableArray alloc] initWithArray:0];
    int seconds_in_day = 60*60*24;// 1 day = 60*60*24 seconds = 86400 seconds
    NSDate *endDate = [startDate dateByAddingTimeInterval:seconds_in_day];

    // use Dictionary for remove duplicates produced by events covered more one year segment
    NSMutableDictionary *eventsDict = [NSMutableDictionary dictionaryWithCapacity:1024];
    NSDate* currentStart = [NSDate dateWithTimeInterval:0 sinceDate:startDate];
    NSDate* currentFinish = [NSDate dateWithTimeInterval:seconds_in_day sinceDate:currentStart];

    if ([currentFinish compare:endDate] == NSOrderedDescending) {
        currentFinish = [NSDate dateWithTimeInterval:0 sinceDate:endDate];
    }
    NSMutableArray *events = [NSMutableArray arrayWithObjects: nil];

    NSArray *calendars = [eventStore
                          calendarsForEntityType:EKEntityTypeReminder];

    NSPredicate *predicate = [eventStore predicateForRemindersInCalendars:calendars];
   //NSPredicate *predicate = [eventStore predicateForIncompleteRemindersWithDueDateStarting:startDate ending:currentFinish calendars:calendars];
    [eventStore fetchRemindersMatchingPredicate:predicate completion:^(NSArray *ekReminders){
        [events addObjectsFromArray:ekReminders];
    }];
}

我收到这个错误:- 对日历守护程序的谓词调用失败:错误域=EKCADErrorDomain 代码=1013“操作无法完成。(EKCADErrorDomain 错误 1013。)”

请帮忙。
