如何获得我所在时区的实际第一个月第一天？

Question

I'm trying to get the first day of the month, but I'm getting the UTC value. I think I need my locale date instead?

Answer 1

I've tried this myself:

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponents = [gregorian components:( NSYearCalendarUnit |
                                                          NSMonthCalendarUnit | NSDayCalendarUnit ) fromDate:[NSDate date]];
[dateComponents setDay:1];
NSLog(@"%@", [gregorian dateFromComponents:dateComponents]);

And it properly prints 2015-04-30 22:00:00 +0000 which would be 1st of May after adding 2 hour (in my case) timezone difference. Just re-check your code, seems like self.calender.currentDate gives wrong month?
