How to find what day of the week for any given date using Cocoa

cocoa, nscalendar, nsdate, nsdatecomponents, objective-c

Solution

I've been doing:

NSDateFormatter* theDateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[theDateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4];
[theDateFormatter setDateFormat:@"EEEE"];
NSString *weekDay =  [theDateFormatter stringFromDate:[NSDate date]];

This has the added bonus of letting you choose how you'd like the weekday to be returned (by changing the date format string in the setDateFormat: call

Problem

I'm trying to figure out what day (i.e. Monday, Friday...) of any given date (i.e. Jun 27th, 2009) Thank you.
