Локальное уведомление с конкретным днем ​​в iOS8

Question

Я хочу отображать локальное уведомление в своем приложении в определенный день, например, я хочу, чтобы уведомление отображалось на все 1 месяца.

У меня есть этот код, как его настроить?

//LOcal Notification 

    NSDate *today = [NSDate new]; 
    NSCalendar *gregorian = 
    [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 

    NSDateComponents *offsetComponents = [NSDateComponents new]; 
    [offsetComponents setDay:???]; 
    [offsetComponents setHour:10]; 
    [offsetComponents setMinute:0]; 

    NSDate *thedate = [gregorian dateByAddingComponents:offsetComponents 
                toDate:today options:0]; 
    UILocalNotification* localNotification = [[UILocalNotification alloc] init]; 
    localNotification.fireDate = thedate; 
    localNotification.alertBody = @"Hey, il serait temps de faire un point non ? \ue104"; 
    localNotification.timeZone = [NSTimeZone defaultTimeZone]; 
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; 
    //END 

Существует слишком обесцененная ошибка с ios8 в gregorian календаре, как я могу его решить?

//assuming you want to fire the notifiaction on 1st of every month. 
NSInteger desiredWeekday = 1;// it specifies on which day of month 
    NSRange weekDateRange = [[NSCalendar currentCalendar] maximumRangeOfUnit:NSWeekdayCalendarUnit]; 
    NSInteger daysInWeek = weekDateRange.length - weekDateRange.location + 1; 

    NSDateComponents *dateComponents = [[NSCalendar currentCalendar] components:NSWeekdayCalendarUnit fromDate:[NSDate date]]; 
    NSInteger currentWeekday = dateComponents.weekday; 
    NSInteger differenceDays = (desiredWeekday - currentWeekday + daysInWeek) % daysInWeek; 
    NSDateComponents *daysComponents = [[NSDateComponents alloc] init]; 
    daysComponents.day = differenceDays; 
    NSDate *resultDate = [[NSCalendar currentCalendar] dateByAddingComponents:daysComponents toDate:[NSDate date] options:0]; 


UILocalNotification* localNotification = [[UILocalNotification alloc] init]; 
    localNotification.fireDate = resultDate; 
    localNotification.alertBody = @"Hey, il serait temps de faire un point non ? \ue104"; 
    localNotification.timeZone = [NSTimeZone defaultTimeZone]; 

    localNotification.repeatInterval = NSMonthCalendarUnit;// repeat notifiaction after a month 
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
