If your goal is to get the dialling code of the user's current location then you should use <a href="https://github.com/HeshamMegid/HMDiallingCode" rel="nofollow noreferrer">HMDiallingCode</a>.

It uses CoreLocation and reverse geocoding to get current country of the user and then retrieve it's dialling code.

I think, you can only get country code for the current Carrier using CoreTelephony framework:

<pre><code>CTTelephonyNetworkInfo *info = [CTTelephonyNetworkInfo new];
CTCarrier *carrier = info.subscriberCellularProvider;

NSLog(@"country code is: %@", carrier.mobileCountryCode);
</code></pre>

If you need a full list of codes for all countries, you need to use some online service for querying it.

I'm afraid there is not a better way. My app include a .plist file with the array of countries with name, code, phone code, trunk code, etc for each. You will not get all that info from iOS API.
If you only need the international phone code for a country code, <a href="http://www.sikosoft.com/item/international_telephone_country_codes_in_xml_format_using_iso_639-1" rel="nofollow">here</a> you are a link with a complete table.

Some countries are not in the switch

I'm quite new to iOS development and I'm currently building my first app.
I'm trying to get a text field to automatically populate the telephone country code for a specific country.

So if for example the user picks "UK" he gets "+44" inserted automatically into that text field.

Currently I'm struggling a way to find how to get the exact country telephone code for the country.
I could create an NSDictionary with all of the countries and country telephone code but I thought there might be a better way.

我对iOS开发非常陌生，目前正在构建我的第一个应用程序。我正在尝试获取一个文本字段，以自动填充特定国家/地区的电话国家代码。例如，如果用户选择了"UK“，他会自动将"+44”插入到文本字段中。目前，我正在努力寻找一种方法来获得准确的国家电话代码。我可以创建一个包含所有国家和国家电话代码的NSDictionary，但我认为可能有更好的方法。
