iphone - 如何在 iOS 中获取用户的国家/地区呼叫代码？

Question

我正在开发一个 iOS 应用程序，用户可以在其中输入他们的手机号码。我如何获得他们的国家电话代码？例如，如果用户在印度，+91则应自动添加前缀。有没有自动添加国家代码的选项？

Answer 1

进口声明：

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

您可以使用 CoreTelephony 框架获取当前运营商的国家代码：

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);

Answer 2

使用NSLocale您可以获得国家名称、代码等。看看下面的代码它将帮助您这样做。

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

对于国家拨号代码，您可以访问此参考代码。

使用这个简单的功能

func getCountryCallingCode(countryRegionCode:String)->String{

        let prefixCodes = ["AF": "93", "AE": "971", "AL": "355", "AN": "599", "AS":"1", "AD": "376", "AO": "244", "AI": "1", "AG":"1", "AR": "54","AM": "374", "AW": "297", "AU":"61", "AT": "43","AZ": "994", "BS": "1", "BH":"973", "BF": "226","BI": "257", "BD": "880", "BB": "1", "BY": "375", "BE":"32","BZ": "501", "BJ": "229", "BM": "1", "BT":"975", "BA": "387", "BW": "267", "BR": "55", "BG": "359", "BO": "591", "BL": "590", "BN": "673", "CC": "61", "CD":"243","CI": "225", "KH":"855", "CM": "237", "CA": "1", "CV": "238", "KY":"345", "CF":"236", "CH": "41", "CL": "56", "CN":"86","CX": "61", "CO": "57", "KM": "269", "CG":"242", "CK": "682", "CR": "506", "CU":"53", "CY":"537","CZ": "420", "DE": "49", "DK": "45", "DJ":"253", "DM": "1", "DO": "1", "DZ": "213", "EC": "593", "EG":"20", "ER": "291", "EE":"372","ES": "34", "ET": "251", "FM": "691", "FK": "500", "FO": "298", "FJ": "679", "FI":"358", "FR": "33", "GB":"44", "GF": "594", "GA":"241", "GS": "500", "GM":"220", "GE":"995","GH":"233", "GI": "350", "GQ": "240", "GR": "30", "GG": "44", "GL": "299", "GD":"1", "GP": "590", "GU": "1", "GT": "502", "GN":"224","GW": "245", "GY": "595", "HT": "509", "HR": "385", "HN":"504", "HU": "36", "HK": "852", "IR": "98", "IM": "44", "IL": "972", "IO":"246", "IS": "354", "IN": "91", "ID":"62", "IQ":"964", "IE": "353","IT":"39", "JM":"1", "JP": "81", "JO": "962", "JE":"44", "KP": "850", "KR": "82","KZ":"77", "KE": "254", "KI": "686", "KW": "965", "KG":"996","KN":"1", "LC": "1", "LV": "371", "LB": "961", "LK":"94", "LS": "266", "LR":"231", "LI": "423", "LT": "370", "LU": "352", "LA": "856", "LY":"218", "MO": "853", "MK": "389", "MG":"261", "MW": "265", "MY": "60","MV": "960", "ML":"223", "MT": "356", "MH": "692", "MQ": "596", "MR":"222", "MU": "230", "MX": "52","MC": "377", "MN": "976", "ME": "382", "MP": "1", "MS": "1", "MA":"212", "MM": "95", "MF": "590", "MD":"373", "MZ": "258", "NA":"264", "NR":"674", "NP":"977", "NL": "31","NC": "687", "NZ":"64", "NI": "505", "NE": "227", "NG": "234", "NU":"683", "NF": "672", "NO": "47","OM": "968", "PK": "92", "PM": "508", "PW": "680", "PF": "689", "PA": "507", "PG":"675", "PY": "595", "PE": "51", "PH": "63", "PL":"48", "PN": "872","PT": "351", "PR": "1","PS": "970", "QA": "974", "RO":"40", "RE":"262", "RS": "381", "RU": "7", "RW": "250", "SM": "378", "SA":"966", "SN": "221", "SC": "248", "SL":"232","SG": "65", "SK": "421", "SI": "386", "SB":"677", "SH": "290", "SD": "249", "SR": "597","SZ": "268", "SE":"46", "SV": "503", "ST": "239","SO": "252", "SJ": "47", "SY":"963", "TW": "886", "TZ": "255", "TL": "670", "TD": "235", "TJ": "992", "TH": "66", "TG":"228", "TK": "690", "TO": "676", "TT": "1", "TN":"216","TR": "90", "TM": "993", "TC": "1", "TV":"688", "UG": "256", "UA": "380", "US": "1", "UY": "598","UZ": "998", "VA":"379", "VE":"58", "VN": "84", "VG": "1", "VI": "1","VC":"1", "VU":"678", "WS": "685", "WF": "681", "YE": "967", "YT": "262","ZA": "27" , "ZM": "260", "ZW":"263"]

我将 Oded 和 LC 的答案组合成一个函数。

func getCountryCode() -> String {
    guard let carrier = CTTelephonyNetworkInfo().subscriberCellularProvider, let countryCode = carrier.isoCountryCode else { return "" }

Answer 6

我认为您需要使用NSLocale用户的国家/地区代码。

您可以点击此链接了解NSLocale类参考的使用。

还要研究这个链接的ISOCountryCode财产。

希望这可以帮助你。

根据以前的答案，我想出了以下代码：

迅速

#if canImport(CoreTelephony)
import CoreTelephony
#endif

static func getRegionCodeFromSim() -> String? {
  #if canImport(CoreTelephony)

  let networkInfos = CTTelephonyNetworkInfo()
  if #available(iOS 12, *) {
    let carrier = networkInfos.serviceSubscriberCellularProviders?
      .map { $0.1 }
      .first { $0.isoCountryCode != nil }
    return carrier?.isoCountryCode
  }
  return networkInfos.subscriberCellularProvider?.isoCountryCode

  #else

  return nil

  #endif
}

static func getRegionCode() -> String? {

    return NSLocale.current.regionCode
  }
  return regionCodeFromSim
}

static func getCountryCode() -> String? {
  guard let regionCode = Self.getRegionCode() else { return nil }
  let prefixCodes = ["AF": "93", "AE": "971", "AL": "355", "AN": "599", "AS":"1", "AD": "376", "AO": "244", "AI": "1", "AG":"1", "AR": "54","AM": "374", "AW": "297", "AU":"61", "AT": "43","AZ": "994", "BS": "1", "BH":"973", "BF": "226","BI": "257", "BD": "880", "BB": "1", "BY": "375", "BE":"32","BZ": "501", "BJ": "229", "BM": "1", "BT":"975", "BA": "387", "BW": "267", "BR": "55", "BG": "359", "BO": "591", "BL": "590", "BN": "673", "CC": "61", "CD":"243","CI": "225", "KH":"855", "CM": "237", "CA": "1", "CV": "238", "KY":"345", "CF":"236", "CH": "41", "CL": "56", "CN":"86","CX": "61", "CO": "57", "KM": "269", "CG":"242", "CK": "682", "CR": "506", "CU":"53", "CY":"537","CZ": "420", "DE": "49", "DK": "45", "DJ":"253", "DM": "1", "DO": "1", "DZ": "213", "EC": "593", "EG":"20", "ER": "291", "EE":"372","ES": "34", "ET": "251", "FM": "691", "FK": "500", "FO": "298", "FJ": "679", "FI":"358", "FR": "33", "GB":"44", "GF": "594", "GA":"241", "GS": "500", "GM":"220", "GE":"995","GH":"233", "GI": "350", "GQ": "240", "GR": "30", "GG": "44", "GL": "299", "GD":"1", "GP": "590", "GU": "1", "GT": "502", "GN":"224","GW": "245", "GY": "595", "HT": "509", "HR": "385", "HN":"504", "HU": "36", "HK": "852", "IR": "98", "IM": "44", "IL": "972", "IO":"246", "IS": "354", "IN": "91", "ID":"62", "IQ":"964", "IE": "353","IT":"39", "JM":"1", "JP": "81", "JO": "962", "JE":"44", "KP": "850", "KR": "82","KZ":"77", "KE": "254", "KI": "686", "KW": "965", "KG":"996","KN":"1", "LC": "1", "LV": "371", "LB": "961", "LK":"94", "LS": "266", "LR":"231", "LI": "423", "LT": "370", "LU": "352", "LA": "856", "LY":"218", "MO": "853", "MK": "389", "MG":"261", "MW": "265", "MY": "60","MV": "960", "ML":"223", "MT": "356", "MH": "692", "MQ": "596", "MR":"222", "MU": "230", "MX": "52","MC": "377", "MN": "976", "ME": "382", "MP": "1", "MS": "1", "MA":"212", "MM": "95", "MF": "590", "MD":"373", "MZ": "258", "NA":"264", "NR":"674", "NP":"977", "NL": "31","NC": "687", "NZ":"64", "NI": "505", "NE": "227", "NG": "234", "NU":"683", "NF": "672", "NO": "47","OM": "968", "PK": "92", "PM": "508", "PW": "680", "PF": "689", "PA": "507", "PG":"675", "PY": "595", "PE": "51", "PH": "63", "PL":"48", "PN": "872","PT": "351", "PR": "1","PS": "970", "QA": "974", "RO":"40", "RE":"262", "RS": "381", "RU": "7", "RW": "250", "SM": "378", "SA":"966", "SN": "221", "SC": "248", "SL":"232","SG": "65", "SK": "421", "SI": "386", "SB":"677", "SH": "290", "SD": "249", "SR": "597","SZ": "268", "SE":"46", "SV": "503", "ST": "239","SO": "252", "SJ": "47", "SY":"963", "TW": "886", "TZ": "255", "TL": "670", "TD": "235", "TJ": "992", "TH": "66", "TG":"228", "TK": "690", "TO": "676", "TT": "1", "TN":"216","TR": "90", "TM": "993", "TC": "1", "TV":"688", "UG": "256", "UA": "380", "US": "1", "UY": "598","UZ": "998", "VA":"379", "VE":"58", "VN": "84", "VG": "1", "VI": "1","VC":"1", "VU":"678", "WS": "685", "WF": "681", "YE": "967", "YT": "262","ZA": "27" , "ZM": "260", "ZW":"263"]
  return prefixCodes[regionCode.uppercased()]
}

如果可用，它会尝试从 SIM 卡（支持多 SIM 卡和非 SIM 卡设备）中获取国家/地区代码，否则将回退到设备的区域设置。prefixCodes可以从 PLIST 或 JSON 加载以帮助提高可读性。

Answer 8

如果您想自动为呼叫国家/地区代码添加前缀，那么您需要务实地获取用户的国家/地区代码并将src 文件夹拖放到您的代码中它看起来像这样：

if let countryCode = (Locale.current as NSLocale).object(forKey: .countryCode) as? String {
        print(countryCode)
        let strCode = Countries.countryFromCountryCode(countryCode: countryCode)
        btnPhoneCode.setTitle("+\(strCode.phoneExtension)", for: .normal)

    }

它对我有用，希望对你也有帮助。:)

    NSLog(@"country code is:%@",countryCode);

您可以请求此网址。
获取CountryCode或ip、region_name、city、long、lat

NSURLRequest *request = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://freegeoip.net/json/"]];

__block NSDictionary *json;
[NSURLConnection sendAsynchronousRequest:request
                                   queue:[NSOperationQueue mainQueue]
                       completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
                           json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
                           NSLog(@"Countrycode: %@", json[@"country_code"]);
 }];
