CLPlacemark的区域设置

Question

我尝试从CLPlacemark对象获取 ISO国家代码区域设置，如“en_US”。当我在对象上执行NSLog时，我会收到很多文本，包括：

address =                         {
                        "localized_address" =                             (
                                                            {
                                address =                                     {
                                    formattedAddressLine =                                         (
                                        "Piccadilly Circus",
                                        "Coventry Street",
                                        London,
                                        W1J,
                                        England
                                    );
                                    structuredAddress =                                         {
                                        administrativeArea = England;
                                        areaOfInterest =                                             (
                                            "Piccadilly Circus",
                                            "Great Britain"
                                        );
                                        country = "United Kingdom";
                                        countryCode = GB;
                                        dependentLocality =                                             (
                                            Mayfair
                                        );
                                        fullThoroughfare = "Coventry Street";
                                        geoId =                                             (
                                        );
                                        locality = London;
                                        postCode = W1J;
                                        subAdministrativeArea = London;
                                        subLocality = Mayfair;
                                        thoroughfare = "Coventry Street";
                                    };
                                };
                                locale = "en_US";

你可以在最后一行看到我需要的信息。但我不知道如何直接访问这些信息。

当我尝试访问CLPlacemark的ISOcountryCode属性时，我只获得GB。

感谢您的帮助 哈德

有点hackish，但这是你可以获取信息的一种方式

NSString *placemarkDescription = [yourPlacemark description];
NSString *regex = @"(locale)(\\s+)(=)(\\s+)("".*?"")(;)";
NSRange localeRange = [placemarkDescription rangeOfString:regex options:NSRegularExpressionSearch];
NSString *locale = [placemarkDescription substringWithRange:localeRange];

正则表达式很丑陋，可能会有所改进（我使用http://txt2re.com），但这应该可以为你获取语言环境。
