Localizable.Stringのような.Stringファイルを使用することはできますが、言語の変更はボタンでできますか？

Question

Localizable.Stringのようなファイルを.Stringでも使用できますが、言語設定ではなくアプリケーションのボタンで言語を変更できますか？ ない場合は、例えばFR関連リンク言語でEN言語を使用する方法を示すための方法があります：FR言語またはEN言語で

が、私は=>FXFormFieldTitle:NSLocalizedString(@"SMSInfo", @"")

使用して、それぞれ、私はそのラインを持っていますEN localizable.String

/* 
    File.strings 
    Formbox 

    Created by OlostA on 04/11/2016.

*/ 
"SMSInfo" = "Do you want to receive the brand informations by sms?"; 

でFR localizable.String

/* 
    File.strings 
    Formbox 

    Created by OlostA on 04/11/2016. 
    Copyright © 2016 NewTelApps. All rights reserved. 
*/ 
"SMSInfo" = "Souhaitez-vous recevoir par sms les informations de la marque ?"; 

、その行で

だから質問。私がFR言語を使用している場合、SMSInfoをlocalizable.strings ENで使用する方法はありますか？
