Getting the last day of a month

Question

How can I get the last day of the current month as an NSDate?

Answer 1

Version from iOS 7

just to get rid of the deprecations... with a minor addition to get the last second of the day.

    // current date
    NSDate *now = [NSDate new];

    // get last day of the current month
    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
    [calendar setTimeZone:[NSTimeZone systemTimeZone]];

    NSRange dayRange = [ calendar rangeOfUnit:NSCalendarUnitDay
                                       inUnit:NSCalendarUnitMonth
                                      forDate:now];

    NSInteger numberOfDaysInCurrentMonth = dayRange.length;

    NSDateComponents *comp = [calendar components:
                              NSCalendarUnitYear |
                              NSCalendarUnitMonth |
                              NSCalendarUnitDay fromDate:now];

    comp.day = numberOfDaysInCurrentMonth;
    comp.hour = 24;
    comp.minute = 0;
    comp.second = 0;

    NSDate *endOfMonth = [calendar dateFromComponents:comp];
