NSLocaleを使用して国名または国コードに基づいて通貨記号を表示したいすべての国名リストがあります。あなただけでは通貨記号とそれを行うことはできませんNSLocaleを使用して国コードまたは国名に基づいて通貨記号を取得
NSLocale *locale = [NSLocale currentLocale];
NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];
NSString *country = [locale displayNameForKey: NSLocaleCurrencyCode value: countryCode];
次のコード使用して国コードの独自のリストとその国の通貨記号を構築することができます。
のObjective-Cを：
- (void)listCountriesAndCurrencies {
NSArray<NSString *> *localeIds = [NSLocale availableLocaleIdentifiers];
NSMutableDictionary<NSString *, NSString *> *countryCurrency = [NSMutableDictionary dictionary];
for (NSString *localeId in localeIds) {
NSLocale *locale = [NSLocale localeWithLocaleIdentifier:localeId];
NSString *country = [locale objectForKey: NSLocaleCountryCode];
if (country && country.length == 2) {
NSString *currency = [locale objectForKey: NSLocaleCurrencySymbol];
countryCurrency[country] = currency;
}
}
NSArray<NSString *> *sorted = [countryCurrency.allKeys sortedArrayUsingSelector:@selector(compare:)];
for (NSString *country in sorted) {
NSString *currency = countryCurrency[country];
NSLog(@"country: %@, currency: %@", country, currency);
}
}
このコードは、すべてのロケールIDのリストから始まります。そこからそれに関連付けられたそれぞれが作成されますNSLocale。ロケールごとに、国コードと通貨記号が抽出されます。これらを使用して、国コードと通貨記号の辞書を作成し、それを印刷します。
はここスウィフト3に翻訳同じコードです：
シミュレートされたiOSの10デバイス上で実行したときにこれは、以下のリストになりfunc listCountriesAndCurrencies() {
let localeIds = Locale.availableIdentifiers
var countryCurrency = [String: String]()
for localeId in localeIds {
let locale = Locale(identifier: localeId)
if let country = locale.regionCode, country.characters.count == 2 {
if let currency = locale.currencySymbol {
countryCurrency[country] = currency
}
}
}
let sorted = countryCurrency.keys.sorted()
for country in sorted {
let currency = countryCurrency[country]!
print("country: \(country), currency: \(currency)")
}
}

：私はそれは$通貨
コードを返すUSAを選択したとします。正しいロケールの通貨として番号をフォーマットする必要があります。
たとえば、ユーロを使用している国が12以上あり、さまざまな方法でお金を表示しています。また、アメリカの通貨記号はアメリカにいる場合は「$」のみです。たとえばカナダではカナダ人が自分の通貨に「$」を使用しているため、カナダでは「US $」です。
、swift3でテストしました。まず、この拡張機能を追加してください。
extension NSLocale {
class func locales1(countryName1 : String) -> String {
let locales : String = ""
for localeCode in NSLocale.isoCountryCodes {
let countryName = (Locale.current as NSLocale).displayName(forKey: .countryCode, value: localeCode)
if countryName1.lowercased() == countryName?.lowercased() {
return localeCode
}
}
return locales
}
}
ここ
let countryCode = NSLocale.locales1(countryName1: "\(place.name)")
let countryCodeCA = countryCode
let localeIdCA = NSLocale.localeIdentifier(fromComponents: [ NSLocale.Key.countryCode.rawValue : countryCodeCA])
let localeCA = NSLocale(localeIdentifier: localeIdCA)
let currencySymbolCA = localeCA.object(forKey: NSLocale.Key.currencySymbol)
let currencyCodeCA = localeCA.object(forKey: NSLocale.Key.currencyCode)
print("\(currencyCodeCA!)")
self.currencyKey = currencyCodeCA! as! String
Xcodeの9•スウィフト4
let currencies = Locale.isoRegionCodes.reduce(into: [String: (code: String, symbol: String)]()) {
let locale = Locale(identifier: Locale.identifier(fromComponents: [NSLocale.Key.countryCode.rawValue: $1]))
$0[$1] = (locale.currencyCode ?? "", locale.currencySymbol ?? "")
}
currencies["US"] // (code "USD", symbol "US$")
currencies["BR"] // (code "BRL", symbol "R$")
currencies["GB"] // (code "GBP", symbol "£")
currencies.sorted{ $0.key<$1.key }.map{ print($0, separator: "", terminator: "\n") }
完璧なソリューション！ –
