我正在开发一个用户输入手机号码的iOS应用程序。我如何获得他们的国家/地区呼叫代码？例如，如果用户在印度，那么+91应该自动加上前缀。是否有自动添加国家/地区代码的选项？
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/地区代码：
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);
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/地区拨打代码，您可以访问this reference code。
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"]
let countryDialingCode = prefixCodes[countryRegionCode]
return countryDialingCode!
}
并打电话给
let currentLocale = NSLocale.currentLocale()
let countryCode = currentLocale.objectForKey(NSLocaleCountryCode) as! String//get the set country name, code of your iphone
print("country code is \(countryCode)")
print(getCountryCallingCode(countryCode))
//change country region Settings>>General>>Language&Region>>Region
迅速
let networkInfo = CTTelephonyNetworkInfo()
if let carrier = networkInfo.subscriberCellularProvider {
print("country code is: " + carrier.mobileCountryCode!);
//will return the actual country code
print("ISO country code is: " + carrier.isoCountryCode!);
}
NSLocale *currentLocale = [NSLocale currentLocale]; // get the current locale.
NSString *countryCode = [currentLocale objectForKey:NSLocaleCountryCode];
// get country code, e.g. ES (Spain), FR (France), etc.
NSLog(@"country code is:%@",countryCode);
NSString*lower=[countryCode lowercaseString];
NSString *path = [[NSBundle mainBundle] pathForResource:@"DiallingCodes" ofType:@"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
NSMutableDictionary *_dictCountry=[[NSMutableDictionary alloc]init];
NSMutableArray *_CodeArray=[[NSMutableArray alloc]init];
[_CodeArray addObject:dict];
_dictCountry = [_CodeArray objectAtIndex:0];
NSString*Country_code=[NSString stringWithFormat:@"+%@",[_dictCountry objectForKey:lower]];
contactTextField.text=Country_code;
您可以要求this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"]);
}];
如果你想自动为调用国家代码加前缀，那么你需要务实地获取用户的国家代码并在你的代码中拖放src Folder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)
}
它适用于我，希望也会帮助你。 :)
