获取国家呼叫前缀
只是想知道是否有简单的方法从用户的手机检索国家的电话代码 。
例如，我的应用程序想为用户预先填写国家/地区呼叫代码。
如果用户位于美国，则返回代码+1，中国为+83，澳大利亚为+61 。
我看了看，但我只能看到：
NSLocale *locale = [NSLocale currentLocale]; NSString *countryCode = [locale objectForKey: NSLocaleCountryCode]; 哪个返回国家代码的缩写，而不是呼叫前缀？
帮助表示赞赏！
请参阅RMPhoneFormat了解提供此信息的类以及格式化电话号码。
注意：这是我创build的。
通过使用coretelephony.framework你可以得到电话号码的国家代码。
CTTelephonyNetworkInfo *info = [CTTelephonyNetworkInfo new]; CTCarrier *carrier = info.subscriberCellularProvider; NSLog(@"Country code is: %@",carrier.mobileCountryCode);
这是一个代码来获得呼叫前缀

#pragma mark - Custom Method -(void)setDefaultCountryCode{ NSString *countryIdentifier = [[NSLocale currentLocale] objectForKey: NSLocaleCountryCode]; NSLog(@"%@",[NSString stringWithFormat:@"+%@",[[self getCountryCodeDictionary] objectForKey:countryIdentifier]]); }
NSLocaleCountryCode是在ISO-3166中定义的国家代码，而不是调用代码。 您需要在别处find调用代码。
请参阅链接了解ISO3166 – >调用代码的完整列表。
我在cocoacontrols.com上遇到了一个更简单的解决scheme。
请检查iOS的国家/地区列表。
它有一个json文件，可以configuration更新更多的信息，并根据需要使用。
使用HMDiallingCode 。 它使用CoreLocation并反向地理编码来确定用户的国家，然后检索它的国际拨号代码。
您需要将所有国家/地区代码放在csv文件中，以便以后可以从该特定文件中读取国家/地区代码，并对特定国家/地区代码的数据进行sorting。 以下是国家代码的完整列表

那么另一种经过validation的方法是为此调用WebService，您可以使用http://www.webservicex.net/country.asmx的GetISD WebMethod并通过当前位置的国家/地区。
通过这种方式，您可以确定从用户访问应用程序的国家/地区获得相关ISD ID。
其他方法是让你所有的ISO国家在你的SQLite数据库，然后你根据当前位置的国家进行查找，并显示相应的条目。
如何检索用户的当前城市名称？ 是使用CLLocationManager查找国家名称的方法。
希望这可以帮助，
谢谢，Jigar
我创build了一个包含国家代码和调用代码的NSDictionary ，可以用来查找调用代码。
使用你的上面的代码和NSDictionary你会做这样的事情…
NSLocale *locale = [NSLocale currentLocale]; NSString *countryCode = [locale objectForKey: NSLocaleCountryCode]; NSString *callingCode = [dictCodes objectForKey:countryCode];
