How to get country code using NSLocale in Swift 3
提问by digidhamu
Could you please help on how to get country code using NSLocalein Swift 3?
你能帮忙了解如何使用NSLocalein获取国家代码Swift 3吗？
This is the previous code I have been using.
这是我之前一直在使用的代码。
NSLocale.currentLocale().objectForKey(NSLocaleCountryCode) as! String
I can get Language Code as below in Swift 3.
我可以在 Swift 3 中获得如下语言代码。
Locale.current.languageCode!
As I can see, fetching languageCode is straight forward but countryCode property is not available.
如我所见，获取 languageCode 很简单，但 countryCode 属性不可用。

You can use regionCode property on Locale struct.
您可以在 Locale 结构上使用 regionCode 属性。
Locale.current.regionCode
It is not documented as a substitute for old NSLocaleCountryCode construct but it looks like it is. The following code checks countryCodes for all known locales and compares them with regionCodes. They are identical.
它没有记录为旧 NSLocaleCountryCode 构造的替代品，但看起来确实如此。以下代码检查所有已知语言环境的 countryCodes，并将它们与 regionCodes 进行比较。它们是相同的。
public func ==(lhs: [String?], rhs: [String?]) -> Bool {
guard lhs.count == rhs.count else { return false }
for (left, right) in zip(lhs, rhs) {
if left != right {
return false
}
}
return true
}
let newIdentifiers = Locale.availableIdentifiers
let newLocales = newIdentifiers.map { Locale(identifier: if let countryCode = (Locale.current as NSLocale).object(forKey: .countryCode) as? String {
print(countryCode)
}
) }
let newCountryCodes = newLocales.map { let locale: NSLocale = NSLocale.current as NSLocale
let country: String? = locale.countryCode
print(country ?? "no country")
// > Prints "IE" or some other country code
.regionCode }
let oldIdentifiers = NSLocale.availableLocaleIdentifiers
newIdentifiers == oldIdentifiers // true
let oldLocales = oldIdentifiers.map { NSLocale(localeIdentifier: let swiftLocale: Locale = Locale.current
let swiftCountry: String? = swiftLocale.countryCode
// > Error "countryCode' is unavailable: use regionCode instead"
) }
let oldLocalesConverted = oldLocales.map { /// Returns the region code of the locale, or nil if it has none.
///
/// For example, for the locale "zh-Hant-HK", returns "HK".
public var regionCode: String? {
// n.b. this is called countryCode in ObjC
if let result = _wrapped.object(forKey: .countryCode) as? String {
if result.isEmpty {
return nil
} else {
return result
}
} else {
return nil
}
}
as Locale }
newLocales == oldLocalesConverted // true
let oldComponents = oldIdentifiers.map { NSLocale.components(fromLocaleIdentifier: //MARK:- Get both country code and Mobile Phone number code
var sendPhoneNumber = ""
if let countryCode = (Locale.current as NSLocale).object(forKey: .countryCode) as? String {
print(countryCode)
if countryCode != ""
{
let getCode = self.getCountryPhonceCode(countryCode)
if getCode != ""
{
sendPhoneNumber = getCode + tfMobileNumber.text!
getOTP(getPhoneNumber: sendPhoneNumber)
}
}
}

Similarly as in NSLocale Swift 3, you have to cast the overlay type Localeback to its
Foundation counterpart NSLocalein order to retrieve the country code:
与NSLocale Swift 3类似，您必须将覆盖类型转换Locale回它的 Foundation 对应类型NSLocale，以检索国家/地区代码：
回答by nevan king
If you make sure that you're using an NSLocaleand not a Localeinstance, you can use the countryCodeproperty:
如果您确定使用的NSLocale是Locale实例而不是实例，则可以使用该countryCode属性：
If you try to use countryCodewith a Swift LocaleXcode will give you an error with a suggestion to use regionCodeinstead:
如果您尝试countryCode与 Swift一起使用，LocaleXcode 会给您一个错误，并建议您regionCode改用：
回答by Mihai Georgescu
NSLocale.countryCodeis the same as Locale.regionCode
NSLocale.countryCode是相同的 Locale.regionCode
This is from Locale.swift
这是来自Locale.swift
