如何从iphone sdk中的ISOCountryCode获取ISOCurrencyCode？

问题描述

我有ISOCountryCode可用，现在我想从ISOCountryCode派生这个国家的currencyCode。我该如何实现？

I have the ISOCountryCode avaliable and now i want to derive the currencyCode of this country from the ISOCountryCode. How can i achieve that?

  NSString *countryCode =  < get from someother view>;     
  NSString *currencyCode = ?;

我从运行时的其他视图收到此国家/地区代码？

I receive this country code from some other view on runtime?

推荐答案

您需要使用NSLocale。要从特定国家/地区代码中检索货币代码：

You will need to use NSLocale. To retrieve the currency code from a specific country code:

NSString *countryCode = @"US";

NSDictionary *components = [NSDictionary dictionaryWithObject:countryCode forKey:NSLocaleCountryCode];
NSString *localeIdent = [NSLocale localeIdentifierFromComponents:components]; 
NSLocale *locale = [[[NSLocale alloc] initWithLocaleIdentifier:localeIdent] autorelease];
NSString *currencyCode = [locale objectForKey: NSLocaleCurrencyCode];

您还可以获取当前区域设置，即用户设置：

You can also get it for the current locale, ie the user settings:

NSString *currencyCode = [[NSLocale currentLocale] objectForKey: NSLocaleCurrencyCode];
