这是我使用模态视图控制器添加事件的代码

EKEventEditViewController *addController = [[EKEventEditViewController alloc] initWithNibName:nil bundle:nil];
EKEvent * eve = [EKEvent eventWithEventStore:self.eventStore];

addController.eventStore = self.eventStore;
addController.event = eve;
[self presentModalViewController:addController animated:YES];

这是用于检索提醒事件的代码

self.eventStore = [[EKEventStore alloc] init];
self.eventsList = [[NSMutableArray alloc] initWithArray:0];

self.defaultCalendar = [self.eventStore defaultCalendarForNewEvents];
self.navigationController.delegate = self;
[self.eventsList addObjectsFromArray:[self fetchEventsForToday]];

获取事件方法

- (NSArray *)fetchEventsForToday {

    NSDate *startDate = [NSDate date];
    NSDate *endDate = [NSDate dateWithTimeIntervalSinceNow:86400];

    NSArray *calendarArray = [NSArray arrayWithObject:defaultCalendar];

    NSPredicate *predicate = [self.eventStore predicateForEventsWithStartDate:startDate endDate:endDate
                                                                    calendars:calendarArray];

    NSArray *events = [self.eventStore eventsMatchingPredicate:predicate];
    return events;
}
