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"];
