推荐答案

所提供的解决方案实际上将返回设备的当前区域 - 而不是当前选择的语言.这些通常是一回事.但是，如果我在北美并将我的语言设置为日语，我所在的地区仍将是英语(美国).为了检索当前选择的语言，您可以:

The solutions provided will actually return the current region of the device - not the currently selected language. These are often one and the same. However, if I am in North America and I set my language to Japanese, my region will still be English (United States). In order to retrieve the currently selected language, you can do:

NSString * language = [[NSLocale preferredLanguages] firstObject];

这将返回当前所选语言的两个字母代码.恩"对于英语，es"西班牙语，de"对于德语等.更多示例，请参阅此维基百科条目(特别是 639-1 列):

This will return a two letter code for the currently selected language. "en" for English, "es" for Spanish, "de" for German, etc. For more examples, please see this Wikipedia entry (in particular, the 639-1 column):

ISO 639-1 代码列表

然后将两个字母代码转换为您想要显示的字符串是一件简单的事情.因此，如果是en"，则显示English".

Then it's a simple matter of converting the two letter codes to the string you would like to display. So if it's "en", display "English".

编辑

值得引用 NSLocale.h 中的头信息:

Worth to quote the header information from NSLocale.h:

+ (NSArray *)preferredLanguages NS_AVAILABLE(10_5, 2_0); // note that this list does not indicate what language the app is actually running in; the [NSBundle mainBundle] object determines that at launch and knows that information
