问题描述

我试图从确定的EKCalendar中获取所有事件，但是如果我用predicateForEventsWithStartDate:endDate:calendars:生成的谓词和过去的'startDate'调用eventsMatching Predicate:，则会得到一个空对象.是个虫子吗?还是没有办法检索过去的事件?

I'm trying to get all the events from a determined EKCalendar, but if I call eventsMatching Predicate: with a predicate generated with predicateForEventsWithStartDate:endDate:calendars: and a past 'startDate' I get a null object. It's a bug? Or there is no way I can retrive the past events?

编辑(NSData十进制):

EDIT (NSData decalarations):

[[self eventStore] predicateForEventsWithStartDate:[NSDate distantPast] endDate:[NSDate distantFuture] calendars:syncedCalendars]

推荐答案

尝试将您的代码更改为:

Try change your code to to:

    NSDate* futureDate =  [NSDate dateWithTimeIntervalSinceNow:[[NSDate distantFuture] timeIntervalSinceReferenceDate]];
    [[self eventStore] predicateForEventsWithStartDate:[NSDate date] endDate: futureDate calendars:syncedCalendars]

还要确保您的syncedCalendars是NSArray类型.

Also make sure that your syncedCalendars is NSArray type.
