我打算为APP集成翻译功能，现在问题是如何获取iOS系统的所有语言的列表，我好方便将iOS的语言的格式和我用的翻译服务的语言格式进行对应。

例如:

zn-Hans -> zh

You can try NSLocale::availableLocaleIdentifiers 以及 NSLocale::componentsFromLocaleIdentifier: these interfaces.

// 获取系统当前支持的语言代号：
NSArray *localeIdentifiers = [NSLocale availableLocaleIdentifiers];

The content is roughly as follows:

(
    eu,
    "hr_BA",
    "en_CM",
    "rw_RW",
    "en_SZ",
    "tk_Latn",
    "uz_Arab",
    "he_IL",
    ar,
    "en_PN",
    as,
    "en_NF",
    "rwk_TZ",
    "zh_Hant_TW",
    "gsw_LI",
    "th_TH",
    "ta_IN",
    "es_EA",
    "fr_GF",
    ...
)
