将事件添加到本机iOS日历,在包含警报时不工作

Question

我有应用程序需要将事件写入本机日历.如果添加EKEvent并不包含EKAlarm,则写入工作正常.如果我包含这行代码:

EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:-30];
event.alarms = [NSArray arrayWithObject:alarm];

未添加日历项目.似乎执行这行代码根本不执行:

[store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];

想法可能是什么问题？

我运行了你的代码(并添加了使其完成所需的内容)并且没有任何问题.许多难以解释的案例的解决方案是清理(构建文件夹)并从设备重置模拟器/删除应用程序.如果您提供更多代码,则更容易找到解决方案.顺便说一下,这是我用过的代码:

- (void)addToCalendar {
    EKEventStore *eventStore = [[EKEventStore alloc] init];

    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        EKEvent *event = [EKEvent eventWithEventStore:eventStore];
        EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:-30];
        event.alarms = [NSArray arrayWithObject:alarm];
        event.title = @"Title";

        NSDateFormatter *df = [[NSDateFormatter alloc] init];
        [df setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
        event.startDate = [df dateFromString:@"2014-02-05 10:00:00"];
        event.endDate = [event.startDate dateByAddingTimeInterval:90*60];
        event.notes = @"Add some notes";

        [event setCalendar:[eventStore defaultCalendarForNewEvents]];

        NSError *err;
        [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
    }];
}
