Iphone 如何在iOS中设置特定时间的提醒，并在该时间间隔2分钟后一次又一次（五次）显示提醒

我有自己的价值

createdate=“2013-09-24 04:29:30”

我必须在这段时间设置提醒。我正在使用本地通知设置提醒，但我不确定在提醒发生后如何删除它，以及在提醒两分钟后如何再次调用它

提前谢谢

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
NSError *err = nil;
BOOL complete = [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
if(err)
{
    NSLog(@"error in storing event");
}
else
    NSLog(@"successfully added");

if(complete)
{
    NSLog(@"successfully added");
}
else
{
    NSLog(@"error in storing event");

我张贴的代码有关添加事件到日历和设置剩余时间，希望你能得到一些想法
