Objective-c get day of week in number starting with Monday, NOT Sunday

Question

I'm making my custom calendar view for an app for the European market. In a function I should get number of day of week... I do, but it returns the number of the day of week starting with Sunday. How should I hardcode returning this number starting with Monday? Thanks Here is what I have so far:

-(int)getWeekDay:(NSDate*)date_
{
    NSLocale *frLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"fr_FR"];

    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    [gregorian setLocale:frLocale];
    NSDateComponents *comps = [gregorian components:NSWeekdayCalendarUnit fromDate:date_];
    int weekday = [comps weekday];

    NSLog(@"Week day is %i", weekday);
    return weekday;

}

Answer 1

You should use [NSCalendar setFirstWeekday:] to do this.
