更改UIImagePickerController中的取消按钮文本

Question

I have a problem. I want to translate the cancel button in a UIImagePickerController . I tried different solutions but none of them worked.

Please find my actual code that works for changing title text but not for cancel button :

func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {    
    imagePicker.navigationBar.topItem?.title = localizedString("ES_CUSTOMERS_EDIT_PHOTOS_TITLE")

    imagePicker.navigationBar.backItem?.title = localizedString("ES_CANCEL_BUTTON")
}

Answer 1

Try this,

    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {

         viewController.navigationItem.title = "your text..!!"    

    }

In Info.plist add (or change if already exists) the Localisations property array to the one you need (eg - Spanish or German or anything)

If you have set the Cancel button using UIBarButtonItem.SystemItem of cancel (or Interface Builder), it will be localized for you automatically as others have mentioned. If you're building the Cancel button yourself for some reason (not needed/recommended if the text is just 'Cancel'), use the appropriate constructor for UIBarButtonItem, for example based on your screenshot:

navigationItem.rightBarButtonItem = UIBarButtonItem(title: NSLocalizedString("Cancel", comment: "Cancel the action"), style: .plain, target: <appropriate target here>)

If you're not sure how localization works in iOS, please see the Apple Localizing Your App documentation.
