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

当应用程序不支持设备UI语言时，有没有办法设置默认语言？

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：
我的应用程序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语言设置为的设备上运行应用程序意大利语该应用将使用密钥字符串 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，必须有一种方法来指定应用程序使用的默认（后备）语言。

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

来自上面的例子应该很清楚，使用英文字符串作为键是行不通的。

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.

默认情况下应该回退到英语。我刚刚将手机切换为我的应用未本地化的语言，文本全部是英文版，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： as @hyperspasm评论：为了扩展/重新定义，回退语言是用户在设备设置中最近选择的语言，也在应用程序包中表示。

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.
