NSDateFormatter display today instead of week day

Question

I use [formatter setDateFormat:@"EEEE, MMMM dd, h:mma"];

So EEEE - show for me a name of the day. But I want to display Today or Tomorrow or Yesterday instead and in another cases display name of the day.

So I want to use format like I've described above an example:

Monday, OCT 2, 4:33PM

but if the Monday is today I want to show:

Today, OCT 2, 4:33PM

If Monday was yesterday it has to show:

Yesterday, OCT 2, 4:33PM

If use this code you suggested as duplicated:

formatter.dateStyle = NSDateFormatterShortStyle;
formatter.timeStyle = NSDateFormatterShortStyle;
formatter.doesRelativeDateFormatting = YES;

10/2/15, 4:33PM which is not so I want to expect.

In example you point as duplicated: how to use NSDateFormatter to see "Today" string there is 2 answer second one it's just display name of the day but not "TODAY" for example, so first answer there I've described above why it does not work, so it's not so right suggestion to say that my question duplicate this link. Maybe it can duplicate another link, but not this one.

Of course I can parse manually received string from formatter to find a day and replace it with "TODAY" if needed, but I just asked if formatter can make it automatically?

Answer 1

Creating an NSDateFormatter that only contains the weekday will do what you want.

NSDate *now = [NSDate date];
NSDateFormatter *weekday = [[[NSDateFormatter alloc] init]    autorelease];
[weekday setDateFormat: @"EEEE"];
NSLog(@"The day of the week is: %@", [weekday stringFromDate:now]);

if you need internationalization, the NSDateFormatter can be sent a locale, which will give the proper translation.

if it doesn't help tell me the result to test another things

Edit

-(NSString *) calculateDay {

int differenceInDays;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"YYYY-MM-DD"];

int differenceInSeconds = fabs([self timeIntervalSinceNow]);

NSCalendar *currentCalendar = [NSCalendar currentCalendar];

// Getting components of the current date.
NSDateComponents *currentDateComponents = [currentCalendar components:NSCalendarCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit | NSWeekdayCalendarUnit | NSTimeZoneCalendarUnit  fromDate:[NSDate date]];
// Getting components of the |date|.
NSDateComponents *dateComponents = [currentCalendar components:NSCalendarCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit | NSWeekdayCalendarUnit | NSTimeZoneCalendarUnit  fromDate:self];
// Getting components of the difference between now and |date|.

NSDateComponents *differenceComponents = [currentCalendar components:NSDayCalendarUnit fromDate:self toDate:[NSDate date] options:0];
// NSDateComponents along with Calendar handles the timezone difference.
[currentDateComponents setTimeZone:[NSTimeZone systemTimeZone]];
[dateComponents setTimeZone:[NSTimeZone systemTimeZone]];
[differenceComponents setTimeZone:[NSTimeZone systemTimeZone]];

differenceInDays = (int)[differenceComponents day];
// This very bad if is because the components:fromDate:toDate:options: calcuates the difference in days with 24hrs difference
// So I had to handle the difference in days myself. -Mepla-
if (differenceInSeconds > [differenceComponents day]*24*3600 + [currentDateComponents hour]*3600 + [currentDateComponents minute]*60 + [currentDateComponents second]){
    differenceInDays++;
}
switch (differenceInDays) {
    case 0:
        return @"Today";
        break;

    case 1:
        return [BLLocalize getTextWithKey:@"Yesterday"];
        break;

    case 2:
    case 3:
    case 4: return [NSString stringWithFormat:@"%@", [[dateFormatter shortWeekdaySymbols] objectAtIndex:[dateComponents weekday]-1]]; // -1 is because the array starts at 0. -Mepla-

        break;

    default:{
        NSString *year = [NSString stringWithFormat:@"%ld", (long)[dateComponents year]];
        return [NSString stringWithFormat:@"%ld/%ld/%@", (long)[dateComponents month], (long)[dateComponents day], [year substringFromIndex: [year  length] - 2]];
    }
        break;
}
