NSDate for each day of month

Question

I've browsed through the stackoverflow, but none of the solutions didn't work well. I want to generate NSDate array of days in month, this is the code I am using (year and month hardcoded for now):

NSCalendar *c = [NSCalendar currentCalendar];
NSRange days = [c rangeOfUnit:NSCalendarUnitDay
                       inUnit:NSCalendarUnitMonth
                      forDate:today];

for (int i = 1; i <= days.length; i++) {
    NSDateComponents *dc = [NSDateComponents new];
    [dc setYear:2015];
    [dc setMonth:12];
    [dc setDay:i];
    NSDate *d = [calendar dateFromComponents:dc];
    [arrayDates addObject:d];
}

The problem is that the first objects would always be(previous month last day) :

2015-11-30 23:00:00 +0000

and the last would be (not the last day of current month) 2015-12-30 23:00:00 +0000

I've tried setting different locale, calendar options, but nothing helps.. any idea?

Thank you

This feels like a timezone/locale problem. I wonder if it goes away if you set an explicit locale and also an explicit hour in the middle of the day:

[calendar setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];

Then, when you're creating the dates, something like this:

[dc setHour:12];

The reason I think it's a timezone/locale issue is because I tried your code here and it worked exactly right first time.
