body: <p>I am trying to open calendar with specific event, I have added events programmatically and all the IDs of these event are persistent.</p>

  <pre><code>-(IBAction)addEvent:(id)sender{
      EKEventStore *store = [[EKEventStore alloc]init];
      [store requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
          if (!granted) { return; }
          EKEvent *event = [EKEvent eventWithEventStore:store];
          event.title = @"Demo Title";
          NSDateComponents *comps=[[NSDateComponents alloc]init];
          [comps setDay:4];
          [comps setMonth:10];
          [comps setYear:2016];
          [comps setHour:12];
          [comps setMinute:1];
  
          NSDate *date=[[[NSCalendar alloc]initWithCalendarIdentifier:NSCalendarIdentifierGregorian] dateFromComponents:comps];
          _date=date;
          event.startDate = date;
          event.endDate=date;
          event.notes=@"This is event description";
  
          EKAlarm *alarm=[EKAlarm alarmWithAbsoluteDate:date];
          [event addAlarm:alarm];
          event.calendar = [store defaultCalendarForNewEvents];
  
          NSError *err=nil;
          [store saveEvent:event span:EKSpanThisEvent commit:YES error:&amp;err];
      }];
