NSDateformatter setDateFormat according to currentLocale

Question

I'm going mad with, probably, a stupid problem.

I have 3 strings: year, month and day. I need to have a date in the right format based on currentLocale, so i.e. if currentLocale localeIdentifier is en_US my dateFormat should be: MMM/dd/yyyy

if it's fr_FR the dateFormat should be dd/MMM/yyyy

I don't think the only way to do this is to get currentLocale localeIdentifier and start with a bunch of if then.

Thanks in advance.

Look at NSDateComponents to create an NSDate, then use NSDateFormatter to format it. NSDateFormatter uses the current locale to format dates, based on the format style (e.g.
NSDateFormatterMediumStyle).

Thank you much. NSDateComponents helped. – Abiosis

If I understand your question, you want to set your NSDateFormatter to the locale of the user's device. For that you can just do something like this:

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
[dateFormatter setTimeStyle:NSDateFormatterNoStyle];
[dateFormatter setLocale:[NSLocale currentLocale]];
NSDate *date = [NSDate date];
NSString *dateString = [dateFormatter stringFromDate:date];

In Swift 3:

let formatter = DateFormatter()
formatter.dateStyle = .medium
formatter.timeStyle = .none
formatter.locale = Locale.current
let date = Date()
let dateString = formatter.string(from: date)
print(dateString)

-(NSString *) stringFromDate:(NSDate *) date{

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

    [dateFormatter setTimeStyle:NSDateFormatterShortStyle];
    [dateFormatter setDateStyle:NSDateFormatterMediumStyle];

    [dateFormatter setLocale:[NSLocale currentLocale]];

    NSString *dateString = [dateFormatter stringFromDate:date];

    [dateFormatter release];

    return dateString;
}

-(NSDate *) dateFromString:(NSString *) dateInString{

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

    [dateFormatter setTimeStyle:NSDateFormatterShortStyle];
    [dateFormatter setDateStyle:NSDateFormatterMediumStyle];

    [dateFormatter setLocale:[NSLocale currentLocale]];

    NSDate *dateFromString = [dateFormatter dateFromString:dateInString];

    [dateFormatter release];

    return dateFromString;
}

I hope this helps.

In case you want to have more flexibility about the format than the formats usable with setDateStyle, have a look at my answer to a similar question: https://mcmap.net/q/420417/-nsdate-in-full-style-but-without-year
