I have value like

createdate = "2013-09-24 04:29:30";

I have to set a reminder on this time .I am using local notification to set the reminder but i am not sure how to remove it after it occurs and also how to invoke it again after two minutes of the reminder time.

Thanks in advance.

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");

    if (granted){

    //for IOS > 6.0
   EKEvent *event = [EKEvent eventWithEventStore:eventStore];
   [event setCalendar:[eventStore defaultCalendarForNewEvents]];

  //no need to fill all fill which one u want to set

Here is the working code ..:) 

  EKEventStore *eventStore = [[EKEventStore alloc] init] ;
  EKEvent *event = [EKEvent eventWithEventStore:eventStore];
   if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {

    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted,   NSError *error) {
        if (granted){
            //---- codes here when user allow your app to access theirs' calendar.
            [event setCalendar:[eventStore defaultCalendarForNewEvents]];

            event.location = @"eventLocation";

            NSDate *newDate = [datePicker.date dateByAddingTimeInterval:24.0f * 60.0f * 60.0f + 120.0f];
