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：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 | // // GDLocalizableController.h // guide-book // // Created by why on 7/16/14. // Copyright (c) 2014 why.

5. 自定义一个宏方便处理：
| 1 2 3 4 | // ----- 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：
| 1 2 3 4 | [GDLocalizableController setUserlanguage:CHINESE]; NSLog(GDLocalizedString( @SUBMIT_BTN_TITLE )); [GDLocalizableController setUserlanguage:ENGLISH]; NSLog(GDLocalizedString( @SUBMIT_BTN_TITLE ));
