NSLocalizedString with variable in Swift

Question

How can I translate a string that has a variable in it like this:

let alert = UIAlertController(title: NSLocalizedString("NEUEARTIKEL",comment:"Bitte gib einen neuen Artikel für \(titelArr[sender.tag]) an:"), message: nil, preferredStyle: .Alert)

When I just translate the String normally like this in the localizable.string:

NEUEARTIKEL="Add an item to \(titelArr[sender.tag]):";

The alert will show (titelArr[sender.tag]) instead of its value.

This is probably very simple, but I`m new to swift an wasn't able to google something helpful! ;-)

Thanks for your help //Seb

In your localisable, you can't setup a custom text directly, you can only use text and format flags. So, in order to get your goal, you can do this:

NEUEARTIKEL="Add an item to %@:";

After that, get your title well-formatted using NSString(format: <#NSString#>, <#args: CVarArgType#>...)

let title = NSString(format: NSLocalizedString("NEUEARTIKEL", nil), titelArr[sender.tag])
let alert = UIAlertController(title: title, message: nil, preferredStyle: .Alert)

Once that done, your localizable string will be formatted as you want.

This is another way and how I do it.

let NEUEARTIKEL = "Add an item to %@:"
let alert = UIAlertController(title: String.localizedStringWithFormat(NSLocalizedString(NEUEARTIKEL, comment: "Bitte gib einen neuen Artikel für \(titelArr[sender.tag]) an:"), titelArr[sender.tag]), message: nil, preferredStyle: .Alert)

basically, the main idea of Localized String with format is like this:

let math = "Math"
let science = "Science"
String.localizedStringWithFormat(NSLocalizedString("I love %@ and %@", comment: "loved Subjects"), math, science)

let myString = String(format: NSLocalizedString("account.by_user", comment: "any comment"), "Peter","Larry")

let title = String(format:
            NSLocalizedString("account.user_count", comment: ""),
                           users.count.description)
