获取iphone当前的显示语言及偏好语言列表

相信大家都知道iphone当前显示的语言，总是偏好语言列表中排序第一位的那个。所以想要获取iphone当前正显示的语言，只需要拿到语言偏好列表数组的第一个原始firstObject即可。

偏好语言列表有如下2种获取方式：

注意：前面一部分是偏好语言列表顺序，最后一部分是地区信息； 当前设置为中国区，打印结果如下：

(lldb) po [NSLocale preferredLanguages]

<__NSArrayM 0x28025a8b0>(

en-CN,

pl-CN,

zh-Hans-CN,

ja-CN,

zh-Hant-CN

)

(lldb)  po [[NSUserDefaults standardUserDefaults] dictionaryRepresentation]

{

"AppleLanguages":[

"en-CN",

"pl-CN",

"zh-Hans-CN",

"ja-CN",

"zh-Hant-CN"

],

"AddingEmojiKeybordHandled":1,

"MSVLoggingMasterSwitchEnabledKey":0,

"AppleLocale":"en_CN",

"NSInterfaceStyle":"macintosh",

"AKLastCheckInAttemptDate":2019-02-21 09:08:42 +0000,

"com.apple.content-rating.AppRating":1000,

"AppleITunesStoreItemKinds":[

"podcast",

"artist",

"itunes-u",

"booklet",

"document",

"movie",

"eBook",

"software",

"software-update",

"podcast-episode"

]

}

再看看切换地区为圣诞岛的打印结果吧：
