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(

));
