Luckily i just wrote this code for one of the apps. Tweak it to suite your app.
And of course handle the error properly.

-(void)makeCalendarEntryWithTitle:(NSString *)title startDate:(NSDate *)startDate endDate:(NSDate *)endDate location:(NSString *)location
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    EKEventStore *eventStore = [[EKEventStore alloc] init];

    EKEvent *anEvent = [EKEvent eventWithEventStore:eventStore];
    anEvent.calendar = eventStore.defaultCalendarForNewEvents;
    anEvent.title = title;
    anEvent.startDate = startDate;
    anEvent.endDate = endDate;
    anEvent.location = location;
        //alarm before 5 minutes of the event
    anEvent.alarms = [NSArray arrayWithObjects:[EKAlarm alarmWithRelativeOffset:-300],nil];

    NSError *error;
    [eventStore saveEvent:anEvent span:EKSpanThisEvent error:&error];

    if(error)
    {
        NSLog(@"Error description - %@",[error localizedDescription]);
    }
    [pool drain];
}
