iOS Get localized version of a string for a specific language

Question

I\'m building an application for iOS that will be available in both English and French languages. I\'ve read some tutorials around internationalization and I have an understandi

Answer 1

Yes, it is possible, but it is not that easy to accomplished.

I just have the case, where I should send one and the same name(for all languages) of a ViewController for GAI (Google Analytics for iOS).

Preconditions:

1) I use the NSBundle extension from here https://stackoverflow.com/a/20257557/3883492 - maybe it is a good idea to look up there first. (It is pretty genius to be honest)

2) I am using swift 2

Here is a pretty simple code sample to illustrate my idea:

func getFrenchString(forKey key: String) -> String {
    if let currentLanguage = (NSUserDefaults.standardUserDefaults().arrayForKey(AppleLanguages)?.first as? String) {
        if currentLanguage == "fr" {
            return NSLocalizedString(key, comment: "")
        }
        else {
            //the application is not currently on `fr`
            //change application to `fr`
            NSBundle.setLanguage("fr")

            //get the localized string on `fr`
            let frString = NSLocalizedString(key, comment: "")

            //return the application to the old language
            NSBundle.setLanguage(currentLanguage)

            return frString
        }
    }

    return ""
}

Also you should have "fr.lproj" folder with localised string in your project.
