我有像

创建日期=“2013-09-24 04:29:30”；

我必须在这个时间设置提醒。我正在使用本地通知来设置提醒，但我不知道如何在它发生后将其删除，以及如何在提醒时间两分钟后再次调用它。

提前致谢。

EKEventStore *eventStore = [[EKEventStore alloc]init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];

//no need to fill all fill which one u want to set
event.title =@"eventTitle";
event.location = @"eventLocation";
event.notes = @"eventNote";
event.startDate =  datePicker.date; //set date
event.URL = [NSURL URLWithString:@"url"];

//for alert set the aleram and notify the user rest is taken care by calendar for u

   EKAlarm *alaram = [[EKAlarm alloc]init];
   [alaram setAbsoluteDate:datePicker.date];
   [event addAlarm:alaram];
//finally add it to calendar

这是工作代码..:) 

  EKEventStore *eventStore = [[EKEventStore alloc] init] ;
