How to Create a Event Notification for calender

NSArray *arrayDate = [strDate componentsSeparatedByString:@"/"];
    NSString *strFinalDate = [NSString stringWithFormat:@"%@-%@-%@ 9:00:00",@"2012",[arrayDate objectAtIndex:0],[arrayDate objectAtIndex:1]];
   
    NSDateFormatter *format = [[NSDateFormatter alloc]init];
    [format setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
    NSDate *startDate = [format dateFromString:strFinalDate];
   
     EKEventStore *eventStore = [[EKEventStore alloc] init];  
    EKEvent *event = [EKEvent eventWithEventStore:eventStore];
   event.title  = [NSString stringWithFormat:@"%@'s Birthday",strName];
   NSDate *twoYearsFromNow = [NSDate dateWithTimeIntervalSinceNow:1577846275];
    double alarmAmountInSeconds = 60*60*9;
   EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:(1.0*alarmAmountInSeconds)];
   EKRecurrenceRule *recurrance;
   recurrance = [[EKRecurrenceRule alloc] initRecurrenceWithFrequency:EKRecurrenceFrequencyYearly interval:1 end:[EKRecurrenceEnd recurrenceEndWithEndDate:twoYearsFromNow]];
   NSMutableArray *arrayReccurence = [NSMutableArray arrayWithObject:recurrance];
   event.recurrenceRules = arrayReccurence;
   event.startDate = startDate;
    event.endDate  = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];
   event.allDay = true;
    event.alarms = [NSArray arrayWithObject:alarm];
   
   [event setCalendar:[eventStore defaultCalendarForNewEvents]];
   NSError *err;
    [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
