1.在Project设置,加入中英两种语言:

2.新建Localizable.strings文件,作为多语言相应的词典,存储多种语言,点击右側Localization,勾选中英:

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvcGxlYXNlY2FsbG1ld2h5/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="" />

3.加入一个字段,

在English中,加入:"SUBMIT_BTN_TITLE" = "Go";

在Chinese中,加入:"SUBMIT_BTN_TITLE" = "開始";

4.一个工具类GDLocalizableController。用来切换本地语言:
//
// GDLocalizableController.h
// guide-book
//
// Created by why on 7/16/14.
// Copyright (c) 2014 why. All rights reserved.
// #import <Foundation/Foundation.h> @interface GDLocalizableController : NSObject +(NSBundle *)bundle;//获取当前资源文件 +(void)initUserLanguage;//初始化语言文件 +(NSString *)userLanguage;//获取应用当前语言 +(void)setUserlanguage:(NSString *)language;//设置当前语言 @end //
// GDLocalizableController.m
// guide-book
//
// Created by why on 7/16/14.
// Copyright (c) 2014 why. All rights reserved.
// #import "GDLocalizableController.h" @implementation GDLocalizableController static NSBundle *bundle = nil; + ( NSBundle * )bundle{
return bundle;
}
+(void)initUserLanguage{ NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
NSString *string = [def valueForKey:@"userLanguage"];
if(string.length == 0){
//获取系统当前语言版本号
NSArray* languages = [def objectForKey:@"AppleLanguages"];
NSString *current = [languages objectAtIndex:0];
string = current;
[def setValue:current forKey:@"userLanguage"];
[def synchronize];//持久化。不加的话不会保存
} //获取文件路径
NSString *path = [[NSBundle mainBundle] pathForResource:string ofType:@"lproj"];
bundle = [NSBundle bundleWithPath:path];//生成bundle
} +(NSString *)userLanguage{ NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
NSString *language = [def valueForKey:@"userLanguage"];
return language;
} +(void)setUserlanguage:(NSString *)language{ NSUserDefaults *def = [NSUserDefaults standardUserDefaults]; //1.第一步改变bundle的值
NSString *path = [[NSBundle mainBundle] pathForResource:language ofType:@"lproj" ];
bundle = [NSBundle bundleWithPath:path]; //2.持久化
[def setValue:language forKey:@"userLanguage"];
[def synchronize];
} @end

5. 自己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"));
