WhatsApp如何在iphone上首次运行时知道国家代码

Question

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是怎么知道的？因为苹果拒绝所有以编程方式使用sim卡信息的应用程序。

Answer 1

我的两分钱：-）使用Swift 3

注意：即使用户在iPhone中没有sim卡，此方法也会起作用。

创建新的属性列表文件intldAlingCodes。plist并粘贴以下行：

在助手类中粘贴以下类或仅粘贴getDialingCode方法，请记住导入CoreTephonery：

        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")
        }
    }

}

用法：

Helper.getDialingCode()

Answer 2

这就是你要找的吗？

NSString *countryCode = [locale objectForKey:NSLocaleCountryCode]; 

Answer 3

在你的房间里。h文件您需要：

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

这个函数会得到国家代码：

-(NSString*)getCountryDialingCode {


NSDictionary *dialingCodes = [[NSDictionary alloc]initWithObjectsAndKeys:
