只是想知道是否有简单的方法可以从用户手机中检索国家/地区呼叫代码。
例如，我的应用程序希望为用户预先填写国家/地区呼叫代码。
如果用户位于美国。将返回代码+1，中国为+83，澳大利亚为+61 。
我环顾四周，但我只能看到：
NSLocale *locale = [NSLocale currentLocale];
NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];
返回国家/地区代码的缩写，而不是调用前缀？
非常感谢帮助！

有关提供此信息以及格式化电话号码的类，请参阅RMPhoneFormat。
注意：这是我创造的。
答案 1 :(得分：5)
使用coretelephony.framework，您可以获取电话号码的国家/地区代码。
CTTelephonyNetworkInfo *info = [CTTelephonyNetworkInfo new];
CTCarrier *carrier = info.subscriberCellularProvider;
NSLog(@"Country code is: %@",carrier.mobileCountryCode);

答案 3 :(得分：1)
NSLocaleCountryCode是ISO-3166中定义的国家/地区代码，而不是调用代码。你需要在其他地方找到调用代码。
有关ISO3166的完整列表，请参阅Link - ＆gt;调用代码。
答案 4 :(得分：1)
使用HMDiallingCode。它使用CoreLocation和反向地理编码来确定用户的国家/地区，然后检索它的国际拨号代码。

答案 6 :(得分：0)
另一种经过验证的方法是为此调用WebService，您可以使用http://www.webservicex.net/country.asmx的GetISD WebMethod并传递当前位置的国家/地区。
通过这种方式，您可以确保从用户访问该应用的国家/地区获取相关的ISD ID。
其他方法是在您的SQLite数据库中包含所有ISO国家/地区，然后根据当前位置的国家/地区执行查找并显示相应的条目。
How to retrieve user's current city name?是使用CLLocationManager查找国家/地区名称的方式。
希望这有帮助，
谢谢， Jigar

您需要将所有国家/地区代码放在csv文件中，以便稍后您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排序。以下是国家/地区代码的完整列表

答案 9 :(得分：-1)
我创建了一个NSDictionary containing country codes and calling codes，可用于查找调用代码。
使用上面的代码和NSDictionary，你会做这样的事情......
NSLocale *locale = [NSLocale currentLocale];
NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];
NSString *callingCode = [dictCodes objectForKey:countryCode];
