How to get the user's country calling code in iOS?

Question

I am developing an iOS app in which the user enters their mobile number. How do I get their country calling code? For example, if a user is in India, then +91 should be prefixed automatically. Is there an option that adds country codes automatically?

Answer 1

Import Statement :

#import<CoreTelephony/CTCarrier.h> #import <CoreTelephony/CTTelephonyNetworkInfo.h> 

you can get country code for the current Carrier using CoreTelephony framework:

CTTelephonyNetworkInfo *network_Info = [CTTelephonyNetworkInfo new]; CTCarrier *carrier = network_Info.subscriberCellularProvider;  NSLog(@"country code is: %@", carrier.mobileCountryCode);  //will return the actual country code NSLog(@"ISO country code is: %@", carrier.isoCountryCode);

with the use of NSLocale you can get the country name, code etc. Take a look at below code it will help you to do so.

NSLocale *currentLocale = [NSLocale currentLocale];  // get the current locale. NSString *countryCode = [currentLocale objectForKey:NSLocaleCountryCode]; // get country code, e.g. ES (Spain), FR (France), etc.
