NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init];

            [outputFormatter setDateFormat:@"yyyy:MM:dd:HH:mm:SS"];

            NSString *tmpDate = nil;

            tmpDate = [outputFormatter stringFromDate:[NSDate date]];

한달뒤

NSDateComponents *components = [[[NSDateComponents alloc] init] autorelease];

components.month = 1;

NSDate *nowDate = [NSDate date];

NSDate *date = [[NSCalendar currentCalendar] dateByAddingComponents:components toDate:nowDate options:0];

요일, 지역

NSDateFormatter *dateFormat = [[[NSDateFormatter alloc] init] autorelease];
        [dateFormat setDateFormat:@"EEEE MMMM d, YYYY"];
        [dateFormat setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"ko_KR"] autorelease]];
