Repeat UILocalNotification on Specific day

Question

I need to set UILocalNotification, I just need to take hour and minute from DatePicker and need to set specific date ( like : Monday ) and repeat it on every Monday.

Answer 1

This solution also takes time in account but it's a bit more simplified than Oren's

-(NSDate *) dateOfSpecificDay:(NSInteger ) day withFireTime:(NSDate *)timeDate/// here day will be 1 or 2.. or 7 and timeDate the current day with the desired time 
{
    NSInteger desiredWeekday = day;
    NSRange weekDateRange = [[NSCalendar currentCalendar] maximumRangeOfUnit:NSCalendarUnitWeekday];
    NSInteger daysInWeek = weekDateRange.length - weekDateRange.location + 1;

    NSDateComponents *dateComponents = [[NSCalendar currentCalendar] components:NSCalendarUnitWeekday fromDate:[NSDate date]];
    NSInteger currentWeekday = dateComponents.weekday;
    NSInteger differenceDays = (desiredWeekday - currentWeekday + daysInWeek) % daysInWeek;
    if (differenceDays == 0) {
        //Check if should register for same day or for next week
        if ([timeDate compare:[NSDate date]] == NSOrderedAscending) {
            //Should schedule for next week
            differenceDays = daysInWeek;
        }
    }

    NSDateComponents *daysComponents = [[NSDateComponents alloc] init];
    daysComponents.day = differenceDays;
    NSDate *resultDate = [[NSCalendar currentCalendar] dateByAddingComponents:daysComponents toDate:timeDate options:0];

    return resultDate;
}
