应用内切换系统语言

创建工具类

// LocalizableTool.h
+(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

// LocalizableTool.m
+ ( NSBundle * )bundle{

    return bundle;
}
+(void)initUserLanguage{

    NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults];

    NSString *string = [userDef valueForKey:kCommonLang];

    if(string.length == 0){
        NSString *current = [WEFileUtils getLangugeAndCountryID][0];
        current = [WEFileUtils returnLocalStr:current];
        string = current;
        [userDef setValue:current forKey:kCommonLang];
        [userDef synchronize];//持久化，不加的话不会保存
    }
    string = [INBaseMethod returnLocalStr:string];
    // 获取文件路径
    NSString *path = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"%@.lproj",string] ofType:nil];
    bundle = [NSBundle bundleWithPath:path];//生成bundle
}

+(NSString *)userLanguage{

    NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults];
    NSString *language = [userDef valueForKey:kCommonLang];
    return language;
}

+(void)setUserlanguage:(NSString *)language{
    // 1.第一步改变bundle的值
    NSString *path = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"%@.lproj",language] ofType:nil];
    bundle = [NSBundle bundleWithPath:path];
}

使用

// 在AppDelegate里进行初始化
 [LocalizableTool initUserLanguage];
// 定义一个宏用来从哪个文件中读数据
// key 代表你要在某个文件中需要读取的key值，table为国际化文件名
#define kLocalizedString(key,comment) [[INLocalizableTool bundle] localizedStringForKey:(key) value:@"" tab
