String pluralizer with NSNumberFormatter

I want to display a nicely formatted integer value via the usual pluralization technology .stringsdict file. (Apple docs here.)

So if I have one thing, I want my output to read

1 thing

But if I have two thousand, three hundred sixty-four things, I want those commas:

2,364 things

but alas the string pluralization technology doesn't give them to me:

2364 things

I can achieve commas with an NSNumberFormatter. I can achieve pluralization with .stringsdict localization technology.

Can I easily achieve both?

Solution

  • Since you already have .stringsdict files setup with the properly plural strings, you don't actually need a number formatter. Simply use the localizedStringWithFormat method of String or NSString.

    Assuming you have setup the localized key "%d things" in your Localizable.strings files and your .stringsdict files, your code would look something like:

    Swift:

    let things = 2364
let localizedString = String.localizedStringWithFormat(NSLocalizedString(@"%d things", @"Your comment"), things)

    Objective-C:

    int things = 2364;
NSString *localizedString = [NSString localizedStringWithFormat:NSLocalizedString(@"%d things", @"Your comment"), things];

    Depending on your locale, the result will be something like:

    2,364 things
    2.364 things
    2 364 things
