当我第一次在iphone上安装whatsapp时，当我打开它时，第一个屏幕已经知道我的SIM卡位置并显示国家代码。 whatsapp如何知道这一点？由于苹果拒绝所有以编程方式使用SIM卡信息的应用程序。

：
#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTTelephonyNetworkInfo.h>
此功能将获得国家/地区代码：

CTTelephonyNetworkInfo *network_Info = [CTTelephonyNetworkInfo new];
CTCarrier *carrier = network_Info.subscriberCellularProvider;
NSString *icc = [dialingCodes objectForKey:[carrier.isoCountryCode uppercaseString]];
return icc;
}
*这仅适用于内置SIM卡的iPhone
答案 1 :(得分：3)
这是你要找的吗？
NSString *countryCode = [locale objectForKey:NSLocaleCountryCode];
答案 2 :(得分：3)
我的两分钱:-)使用Swift 3
注意： 即使用户没有iPhone中的SIM卡，此方法也能正常工作。

在Helper类中粘贴以下类或getDialingCode方法，请记住导入CoreTelephony：
import Foundation
import CoreTelephony
class Helper {
static func getDialingCode() {
let countryCode = CTTelephonyNetworkInfo().subscriberCellularProvider?.isoCountryCode ?? Locale.current.regionCode!
let path = Bundle.main.path(forResource: "IntlDialingCodes", ofType: "plist")!
let dict = NSDictionary(contentsOfFile: path)!
if let dialingCode = dict[countryCode.lowercased()] as? String {
print("Dialing code for \"\(countryCode.uppercased())\" is \"+\(dialingCode)\"")
} else {
print("Dialing code for \"\(countryCode.uppercased())\" not found in plist file")
}
}
}
<强>用法：
Helper.getDialingCode()
