How to use NSLocalizedString function with variables in Swift?
Solution 1
You can use the sprintf
format parameters within NSLocalizedString
, so your example can look like this:
let myString = String(format: NSLocalizedString(" - %d Notifica", comment: "sottotitolo prescrizione per le notifiche al singolare"), count)
Solution 2
In Session #412 of the WWDC2014 "Localizing with Xcode 6" the proper way to this in Swift is the following:
String.localizedStringWithFormat(
NSLocalizedString(" - %d Notifica",
comment: "sottotitolo prescrizione per le notifiche al singolare"),
count)
Solution 3
I have followed the approach of creating extension to String as i have many strings to localize.
extension String {
var localized: String {
return NSLocalizedString(self, comment:"")
}
}
To use it for localization in code do:
self.descriptionView.text = "Description".localized
For strings with dynamic variables follow :
self.entryTimeLabel.text = "\("Doors-open-at".localized) \(event.eventStartTime)"
Declare the strings in String files for different languages (example : Arabic and English)
Hope will be helping!
Solution 4
Here is an extension I use in String, it adds a localizeWithFormat function with variable arguments,
extension String:{
func localizeWithFormat(arguments: CVarArg...) -> String{
return String(format: self.localized, arguments: arguments)
}
var localized: String{
return Bundle.main.localizedString(forKey: self, value: nil, table: "StandardLocalizations")
}
}
Usage:
let siriCalendarText = "AnyCalendar"
let localizedText = "LTo use Siri with my app, please set %@ as the default list on your device reminders settings".localizeWithFormat(arguments: siriCalendarTitle)
Just be careful not to use the same function and property names that String has. I normally use a 3 letter prefix for all my framework functions.
Solution 5
I tried the above solutions however the code below worked for me
SWIFT 4
extension String {
/// Fetches a localized String
///
/// - Returns: return value(String) for key
public func localized() -> String {
let path = Bundle.main.path(forResource: "en", ofType: "lproj")
let bundle = Bundle(path: path!)
return (bundle?.localizedString(forKey: self, value: nil, table: nil))!
}
/// Fetches a localised String Arguments
///
/// - Parameter arguments: parameters to be added in a string
/// - Returns: localized string
public func localized(with arguments: [CVarArg]) -> String {
return String(format: self.localized(), locale: nil, arguments: arguments)
}
}
// variable in a class
let tcAndPPMessage = "By_signing_up_or_logging_in,_you_agree_to_our"
.localized(with: [tAndc, pp, signin])
// Localization File String
"By_signing_up_or_logging_in,_you_agree_to_our" = "By signing up or logging in, you agree to our \"%@\" and \"%@\" \nAlready have an Account? \"%@\"";

I'm trying to localize my app using
NSLocalizedString
. When I import the XLIFF file, most works like a charm but something do not and some string is not localized. I have noticed that the problem is fromNSLocalizedString
containing something variable inside like:NSLocalizedString(" - \(count) Notifica", comment: "sottotitolo prescrizione per le notifiche al singolare")
or
NSLocalizedString("Notifica per \(medicina!) della prescrizione \(prescription!)\nMemo: \(memoTextView.text)", comment: "Messaggio della Local Notification")
Maybe this is not the correct syntax for this kind of stuff. Someone can explain me how to do that in Swift?
