iOS开发Xcode中切换显示语言实现国际化
1.在Project设置,添加中英两种语言:
2.新建Localizable.strings文件,作为多语言对应的词典,存储多种语言,点击右侧Localization,勾选中英:
3.添加一个字段,
在English中,添加:SUBMIT_BTN_TITLE = Go;
在Chinese中,添加:SUBMIT_BTN_TITLE = 开始;
4.一个工具类GDLocalizableController,用来切换本地语言:

5. 自定义一个宏方便处理:

// ----- 多语言设置 #define CHINESE @zh -Hans #define ENGLISH @en #define GDLocalizedString(key) [[GDLocalizableController bundle] localizedStringForKey:(key) value:@ table:nil] |
6.使用:

[GDLocalizableController setUserlanguage:CHINESE]; NSLog(GDLocalizedString( @SUBMIT_BTN_TITLE )); [GDLocalizableController setUserlanguage:ENGLISH]; NSLog(GDLocalizedString( @SUBMIT_BTN_TITLE ));
