使用NSLocale根据国家/地区代码或国家/地区名称获取货币符号

您可以建立自己的国家/地区代码列表国家/地区的货币符号使用以下代码：

You can build your own list of country codes and that country's currency symbol using the following code:

Objective-C：

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);
    }
}

此代码以所有区域设置ID列表开头。从那里创建每个关联的 NSLocale 。对于每个区域设置，将提取国家/地区代码和货币符号。这些用于构建国家代码和货币符号的字典，然后打印出来。

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.

以下是转换为Swift 3的相同代码：

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)")
    }
}
