Get the iDevice system language to issue an IF

Question

I'm trying to get the system language ofrom the iDevice of the user, basically I want 1 image if it'S in french, and another if it's english

any ideas ?

My code (that doesn't display the image either way)

let preferredLanguage = NSLocale.preferredLanguages()[0] as String

if preferredLanguage == "en" {
    navigationItem.titleView = imageView
} else if preferredLanguage == "fr" {
    navigationItem.titleView = imageViewFR
}

sorry meant it to show "fr" i corrected it, and the image is not showing. it's the UINavigationBar Title that i'm changing, no IF it's good. With the IF condition it doesn't work — Jp4Real, Mar 22 '16 at 17:57
NSLocale.preferredLanguages [can return a variety of identifiers](https://developer.apple.com/library/ios/technotes/tn2418/_index.html#//apple_ref/doc/uid/DTS40016588-CH1-LANGUAGE_IDENTIFIERS_IN_IOS_9)... `"en" != "en-US"` — André Dion, Mar 22 '16 at 18:00
ok, is there anything other than NSLocale I can use ? to put simply I want it to be another image only if the system language is french, else I want it to be then english image — Jp4Real, Mar 22 '16 at 18:03
Try getting the `NSLocaleLanguageCode` value from the current locale instead of looking at the list of preferred languages. — rmaddy, Mar 22 '16 at 18:04
here's my new constant : `let preferredLanguage = NSLocale.currentLocale().objectForKey(NSLocaleLanguageCode) as! String` which returns `en` (in this case) but the code inside the if statement doesn't display — Jp4Real, Mar 22 '16 at 18:11

You don't need to write (error-prone) just to localize an image. Just put the image files into the appropriate localization folder in your app bundle — then APIs like NSBundle.pathForResource and UIImage(named:) will automatically load the image corresponding to the user's preferred language. (And if the images for different languages have different dimensions, you don't need separate image views — just use Auto Layout.)

See Localized Resources in Bundles and Adding Additional Resources You Want to Localize in Apple's docs.

thanks a lot the link especially was very helpful – Jp4Real Mar 23 '16 at 19:36 — Jp4Real, Mar 23 '16 at 19:36

Turns out @rmaddy was right, here's the answer

    let preferredLanguage = NSLocale.currentLocale().objectForKey(NSLocaleLanguageCode) as! String

    if preferredLanguage == "fr" {
        navigationItem.titleView = imageViewFR
    } else {
        navigationItem.titleView = imageView
    }

to get the system language we need to use NSLocale.currentLocale() then it worked ! thanks @rmaddy

That's the wrong way to handle localized images on iOS. See @rickster's answer for the right way. – Tom Harrington Mar 22 '16 at 19:57
