在 iOS 中本地化字符串:默认(后备)语言? [英] Localizing strings in iOS: default (fallback) language?

问题描述

当应用不支持设备 UI 语言时，是否可以设置默认语言?

Is there a way to set a default language to be used when the device UI language is not supported by an app?

示例:我的应用已本地化为英语和德语:

Example: My app is localized into English and German:

// en.lproj:
"POWER_TO_THE_PEOPLE_BTN" = "Power";
"POWER_PLUG_BTN" = "Power";

// de.lproj:
"POWER_TO_THE_PEOPLE_BTN"  = "Macht";
"POWER_PLUG_BTN" = "Spannung";

现在，如果我在 UI 语言设置为 Italian 的设备上运行应用程序，应用程序将使用键字符串 POWER_TO_THE_PEOPLE_BTN 和 POWER_PLUG_BTN.

Now, if I run the app on a device with UI language set to Italian the app will use the key strings POWER_TO_THE_PEOPLE_BTN and POWER_PLUG_BTN.

在这种情况下，必须有一种方法可以指定应用程序使用的默认(备用)语言.

There must be a way to specify a default (fallback) language to be used by the application in such a case.

从上面的例子可以看出，使用英文字符串作为key是行不通的.

From the above example it should be clear that using the English string as a key will not work.

我现在看到的唯一选择是使用 NSLocalizedStringWithDefaultValue 而不是 NSLocalizedString.

The only option I see right now is to use NSLocalizedStringWithDefaultValue instead of NSLocalizedString.

也许这应该有帮助?-- iPhone:本地化/国际化默认字符串文件

Perhaps this should help? -- iPhone: localization / internationalization default strings file

默认情况下它应该回退到英语.我刚刚将我的手机切换到我的应用程序未本地化的语言，并且文本都是英文的，正如预期的那样.

It should fallback to English by default. I've just switched my phone to a language into which my app is not localized, and the text was all in English, as expected.

重要提示: 正如@hyperspasm 评论的那样:为了扩展/改写这一点，后备语言是用户最近在设备设置中选择的语言，它也在应用程序的捆绑.

Important: as @hyperspasm commented : To expand on/rephrase this, the fallback language is the language which was most recently chosen by the user in the device Settings, that is also represented in the app's bundle.
