从iPhone设备UDID获取国家/地区代码？

Question

I am trying to get the country code from iPhone device UDID. I found this

NSLocale *locale = [NSLocale currentLocale];
NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];
NSString *countryName = [locale displayNameForKey:NSLocaleCountryCode value:countryCode];

It is working fine in local settings but I want to get the country code from device UDID. Is it passable?

Thanks...

UDID不包含有关国家/地区代码的信息。

You can do like this

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

// Setup the Network Info and create a CTCarrier object
CTTelephonyNetworkInfo *networkInfo = [[[CTTelephonyNetworkInfo alloc] init] autorelease];
CTCarrier *carrier = [networkInfo subscriberCellularProvider];

// Get carrier name
NSString *carrierName = [carrier carrierName];
if (carrierName != nil)
  NSLog(@"Carrier: %@", carrierName);

// Get mobile country code
NSString *mcc = [carrier mobileCountryCode];
if (mcc != nil)
  NSLog(@"Mobile Country Code (MCC): %@", mcc);

// Get mobile network code
NSString *mnc = [carrier mobileNetworkCode];
if (mnc != nil)
  NSLog(@"Mobile Network Code (MNC): %@", mnc);
