在iPhone上NSLocalizedString返回iPhone语言的字符串。 是否有可能强制NSLocalizedString使用特定语言来拥有应用程序 用不同的语言吗?


当前回答

你可以这样做:

NSString *bundlePath = [[NSBundle mainBundle] pathForResource:@"Localizable" ofType:@"strings" inDirectory:nil forLocalization:@"es"];


NSBundle *spanishBundle = [[NSBundle alloc] initWithPath:[bundlePath stringByDeletingLastPathComponent]];

NSLocalizedStringFromTableInBundle(@"House", nil, spanishBundle, nil):

其他回答

你可以用你想要做这件事的本地化字符串集构建一个子bundle,然后使用NSLocalizedStringFromTableInBundle()来加载它们。(我假设这是与你可能在应用上做的正常UI本地化分开的内容。)

你觉得Swift 3的这个解决方案怎么样?

extension String {

    func localized(forLanguage language: String = Locale.preferredLanguages.first!.components(separatedBy: "-").first!) -> String {

        guard let path = Bundle.main.path(forResource: language == "en" ? "Base" : language, ofType: "lproj") else {

            let basePath = Bundle.main.path(forResource: "Base", ofType: "lproj")!

            return Bundle(path: basePath)!.localizedString(forKey: self, value: "", table: nil)
        }

        return Bundle(path: path)!.localizedString(forKey: self, value: "", table: nil)
    }
}

简单的用法:

"report".localized(forLanguage: "pl") //forced language
"report".localized() //default language selected by user in settings, in case when your app doesnt support selected lanaguage, the default one is selected, here is an english.

也许你应该补充这个(在.pch文件#import后):

extern NSBundle* bundle; // Declared on Language.m

#ifdef NSLocalizedString
    #undef NSLocalizedString
    // Delete this line to avoid warning
    #warning "Undefining NSLocalizedString"
#endif

#define NSLocalizedString(key, comment) \
    [bundle localizedStringForKey:(key) value:@"" table:nil]

正如Brian Webster提到的,语言需要在“应用程序启动初期的某个时候”设置。我认为AppDelegate的applicationDidFinishLaunching:应该是一个合适的地方来做它,因为它是我做所有其他初始化的地方。

但正如威廉·丹尼斯提到的,这似乎只有在应用程序重新启动后才会起作用,这有点没用。

不过,如果我把代码放在main函数中,它似乎工作得很好:

int main(int argc, char *argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    // Force language to Swedish.
    [[NSUserDefaults standardUserDefaults]
     setObject:[NSArray arrayWithObject:@"sv"]
     forKey:@"AppleLanguages"];

    int retVal = UIApplicationMain(argc, argv, nil, nil);
    [pool release];
    return retVal;
}

如果有任何评论,我将不胜感激。

对于我的案例,我有两个本地化文件,ja和en

如果系统中首选语言既不是en也不是ja,我希望将其强制为en

我要编辑主体部分。m文件

我会检查第一种首选语言是en还是ja,如果不是,那么我会把第二种首选语言改为en。

int main(int argc, char *argv[])
{

    [[NSUserDefaults standardUserDefaults] removeObjectForKey:@"AppleLanguages"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    NSString *lang = [[NSLocale preferredLanguages] objectAtIndex:0];

    if (![lang isEqualToString:@"en"]  &&  ![lang isEqualToString:@"ja"]){

        NSMutableArray *array = [[NSMutableArray alloc] initWithArray:[NSLocale preferredLanguages]];
        [array replaceObjectAtIndex:1 withObject:@"en"];

        [[NSUserDefaults standardUserDefaults] setObject:array forKey:@"AppleLanguages"];
        [[NSUserDefaults standardUserDefaults] synchronize];


    }

    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));


    }


}
