Answer 1

Ok, since I'm rolling my own calendar control, I went ahead and created a NSCalendar category. Here's my lastOfMonth method:

- (NSDate *)lastOfMonth:(NSDate *)date
{
    NSDateComponents *dc = [self components:NSEraCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit fromDate:date];

    NSRange dim = [self rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:date];
    dc.day = dim.length;

    return [self dateFromComponents:dc];
}
