检测iOS应用程序正在使用的语言 [英] Detect language in use by iOS application

问题描述

如何检测当前的应用程序语言?我不是在谈论NSLocale用户首选项.

How can I detect the current application language ? I am not talking about NSLocale user preferences.

在我的应用中，当前支持两种语言.默认的"en"和特定的"it".

In my app there are currently two supported languages. A default 'en' and a specific 'it'.

我只是想知道实际使用的是哪一个.如果相关，作为进一步的说明，我将通过Web服务仅针对两种受支持的语言提供内容.调用服务时，我需要传递语言参数.目前，我正在执行此操作，但它确实有效，但是我完全不喜欢它:

I just wanted to know which one is actually in use. If it is relevant, as a further explanation, I am providing content trough a web service only for the two supported languages. When invoking the service I need to pass a language parameter. Currently I am doing this, it works, but I totally dislike it:

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

if (![preferredLanguage isEqualToString:@"it"] && ![preferredLanguage isEqualToString:@"en"]) {
    return @"en";
}
return preferredLanguage;

我已经看过NSLocale，class和UIApplication，但是没有找到有用的东西.

I have looked trough the NSLocale class and UIApplication, but didn't manage to find anything useful.

我还注意到NSBundle有一些本地化方法，但是它们似乎都没有具体说明正在使用哪种方法.

I also notice that NSBundle has some localization methods, but they all seems not specific about which one is in use.

推荐答案

我通常在Localizable.strings中保留一个特殊键，例如"HTTPAcceptLanguage"，我将其设置为"en"，"fr"等.您的服务器上，应用程序显示的语言非常简单，如NSLocalizedString(@"HTTPAcceptLanguage"，nil).

I usually reserve a special key in Localizable.strings, such as "HTTPAcceptLanguage", which I set to "en", "fr", etc. Now telling your server the language displayed by the application is as simple as NSLocalizedString(@"HTTPAcceptLanguage", nil).
