Get first day in a month from NSCalendar

Question

I have this subset of a method that needs to get day one of the current month.

NSDate *today = [NSDate date];  // returns correctly 28 february 2013
NSCalend         


        

Answer 1

Your logic is wrong: Instead of setting the date's day to 1, you're adding a day to the current date.

Try something like that:

NSDate *today = [NSDate date];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

NSDateComponents *components = [gregorian components:(NSEraCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit) fromDate:today];
components.day = 1;

NSDate *dayOneInCurrentMonth = [gregorian dateFromComponents:components];
