I want to display Currency Symbol based on Country name or country code using NSLocale I have all the country name list. suppose I have selected USA then it Return $ Currency
Code :
NSLocale *locale = [NSLocale currentLocale];
NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];
NSString *country = [locale displayNameForKey: NSLocaleCurrencyCode value: countryCode];
You can build your own list of country codes and that country's currency symbol using the following code:
Objective-C:
- (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);
}
}
This code starts with the list of all locale ids. From there it creates each associated NSLocale. For each locale, the country code and currency symbol is extracted. These are used to build a dictionary of country codes and currency symbols which are then printed out.
Here's the same code translated to Swift 3:
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)")
}
}
This results in the following list when run on a simulated iOS 10 device:

Xcode 10 • Swift 4.2 or later
extension Locale {
static let currency: [String: (code: String?, symbol: String?)] = Locale.isoRegionCodes.reduce(into: [:]) {
let locale = Locale(identifier: Locale.identifier(fromComponents: [NSLocale.Key.countryCode.rawValue: $1]))
$0[$1] = (locale.currencyCode, locale.currencySymbol)
}
}
Locale.currency["US"] // (code "USD", symbol "US$")
Locale.currency["BR"] // (code "BRL", symbol "R$")
Locale.currency["GB"] // (code "GBP", symbol "£")
Locale.currency["PT"] // (code "EUR", symbol "€")

You can Get currency code from Country name, tested it on swift3, first of all add this extension
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
}
}
You will get the currency code from here
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
You can't do that with the currency symbol alone. You have to let the system format your numbers as a currency with the correct locale.
For example, there are over a dozen countries using Euros, and they display money in different ways. And the currency symbol for the USA is only "$" if you are in the USA - in Canada, for example, it is "US$" because Canadians use "$" for their own currency.
