NSDate month and week day localized

Question

I'm trying to display a localized date (with the week day and month in letters) depends on the language of the phone (not the region format).

I tried :

// Date formatter
NSDateFormatter* df = [[NSDateFormatter alloc] init];
NSLocale* locale = [NSLocale currentLocale];
NSLog(@"locale : %@", locale.localeIdentifier);
[df setDateFormat:[NSDateFormatter dateFormatFromTemplate:@"EEEE dd MMMM" options:0 locale:[NSLocale currentLocale]]]; 

But when I change the language of the phone, it changes nothing, it still displays in french. How can I make it work ?

Answer 1

Try this one;

First we get the device language, then we set the locale of NSDateFormatter with that language.

NSString * deviceLanguage = [[NSLocale preferredLanguages] objectAtIndex:0];
NSDateFormatter * dateFormatter = [NSDateFormatter new];
NSLocale * locale = [[NSLocale alloc] initWithLocaleIdentifier:deviceLanguage];

[dateFormatter setDateFormat:@"EEEE dd MMMM"];
[dateFormatter setLocale:locale];

NSString * dateString = [dateFormatter stringFromDate:[NSDate date]];

NSLog(@"%@", dateString);

Answer 2

You are testing it wrong. What you should do is change the Region Format, not the Language of the device.

Go to Settings->General->International->Region Format to change it and test it again.

I hope it helps.

EDIT: Using the Language is not a good idea. iOS is not translated to that many languages. However it supports a lot of region formats.

Example: I live in Bulgaria. iOS is not translated to bulgarian, so the actual menus and apps use English language, but as I have set my Region Format to Bulgaria, all of the date formats, date labels and currency labels are the bulgarian ones.
