title: Change cancel button text in UIImagePickerController
body: <p>I have a problem.
  I want to translate the cancel button in a <code>UIImagePickerController</code>.
  I tried different solutions but none of them worked.</p>
  
  <p>Please find my actual code that works for changing title text but not for cancel button :</p>
  
  <pre><code>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")
  }
  </code></pre>
