iOS 多语言的切换

一、添加应用程序需要支持的国际语言

二、新建一个Localizable.strings文件，作为多语言对应的词典，存储多种语言

三、在Localizable.strings的对应文件以键值对的形式配置

四、可以创建一个类（InternationalControl）来自由切换语言

InternationalControl.h

#import <Foundation/Foundation.h>

@interface InternationalControl : 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

InternationalControl.m

#import "InternationalControl.h"

@implementation InternationalControl

static NSBundle *bundle = nil;

+ ( NSBundle * )bundle{

return bundle;

}

+(void)initUserLanguage{

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];

NSString *string = [def valueForKey:@"userLanguage"];

//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:@"AppleLanguages"][0];

return language;

}

+(void)setUserlanguage:(NSString *)language{

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];

NSString *path = [[NSBundle mainBundle] pathForResource:language ofType:@"lproj" ];

bundle = [NSBundle bundleWithPath:path];

[def setValue:language forKey:@"userLanguage"];

[def synchronize];

}

@end

五、使用这个语言类

　　[InternationalControl initUserLanguage];

　　[InternationalControl setUserlanguage:[InternationalControl userLanguage]];

　　NSLog(@"language-------%@",[InternationalControl userLanguage]);

　　// 这样就可以多语言切换了

　　self.title = [[InternationalControl bundle] localizedStringForKey:@"login_success" value:nil table:@"Localizable"];
