Question

是否可以使用像.String这样的Localizable.String文件，但语言是否会更改应用程序中的按钮而不是设置中的语言？如果没有，有没有办法说明如何在EN语言中使用FR语言，例如：

在FR语言或EN语言中，我使用=＆gt; FXFormFieldTitle:NSLocalizedString(@"SMSInfo", @"")

分别我在FR localizable.String

中有那条线

/* 
  File.strings
  Formbox

*/
"SMSInfo" = "Souhaitez-vous recevoir par sms les informations de la marque ?";

EN localizable.String中的那一行

/* 
  File.strings
  Formbox

  Created by OlostA on 04/11/2016.
  Copyright © 2016 NewTelApps. All rights reserved.
*/
"SMSInfo" = "Do you want to receive the brand informations by sms?";

那么问题。如果我使用FR语言，有没有办法在localizable.strings EN中使用SMSInfo？

是的，可以从app更改语言。

[LanguageManager saveLanguageByIndex:indexPath.row andCode:model.strLanguageCode];

LanguageManager.h

#import <Foundation/Foundation.h>

typedef NS_ENUM(NSInteger, ELanguage)
{
    ELanguageEnglish,
    ELanguageSpanish,
    ELanguageFrench,
    ELanguageGerman,
    ELanguageItalian,
    ELanguageArabic,
    ELanguageChinese,


    ELanguageCount
};

@interface LanguageManager : NSObject

+ (NSArray *)languageStrings;
+ (NSString *)currentLanguageString;
+ (NSString *)currentLanguageCode;
+ (NSInteger)currentLanguageIndex;
+ (void)saveLanguageByIndex:(NSInteger)index andCode:(NSString *)strCode;

是否可以使用类似Localizable.String的.String文件，但语言是否随按钮而变化？
