ios - 从 CLPlacemark 项中提取 dependentLocality

Question

我正在尝试提取在 CLPlacemark 对象中返回的 dependentLocality 信息。数据(匿名)看起来像

{
            "cache_control" = CACHEABLE;
            "start_index" = 0;
            status = "STATUS_SUCCESS";
            ttl = 15768000;
            type = "COMPONENT_TYPE_ADDRESS";
            value =                 (
                                    {
                    address =                         {
                        "known_accuracy" = POINT;
                        "localized_address" =                             (
                                                            {
                                address =                                     {
                                    formattedAddressLine =                                         (
                                        "111 Some St",
                                        "Brooklyn, NY  11111-1111",
                                        "United States"
                                    );
                                    structuredAddress =                                         {
                                        administrativeArea = "New York";
                                        administrativeAreaCode = NY;
                                        areaOfInterest =                                             (
                                            "Long Island"
                                        );
                                        country = "United States";
                                        countryCode = US;
                                        dependentLocality =                                             (
                                            "Bedford Stuyvesant",
                                            Brooklyn
                                        );
                                        fullThoroughfare = "111 Some St";
                                        geoId =                                             (
                                        );
                                        locality = "New York";
                                        postCode = 11206;
                                        postCodeExtension = 1111;
                                        postCodeFull = "11111-1111";
                                        subAdministrativeArea = Kings;
                                        subLocality = Brooklyn;
                                        subThoroughfare = 111;
                                        thoroughfare = "Some St";
                                    };
                                };
                                locale = "en_US";
                            }
                        );
                    };
                }
            );
            "values_available" = 1;
            version = 7;
            "version_domain" =                 (
                apple,
                revgeo,
                US
            );
        },

我无法访问内容(除了通过 Apple 的 structuredAddress 属性，它不包含我想要的内容)。例如，我想从上面的内容中提取“Bedford Stuyvesant, Brooklyn”。为此尝试了多种方法，但例如，将地标转换到 NSDictionary 失败。任何帮助将不胜感激!

也许您可以进行一些字符串处理以从 placemark.description 中提取 dependentLocality。但为什么不直接使用 placemark.subLocality 属性呢？

NSString *geoMapItem = placemark.description;
NSRange start = [geoMapItem rangeOfString:@"dependentLocality"];
NSRange end = [geoMapItem rangeOfString:@")" options:NSCaseInsensitiveSearch range:NSMakeRange(start.location, 1000)];
NSString *dataString = [geoMapItem substringWithRange:NSMakeRange(start.location, end.location - start.location + end.length)];
dataString = [dataString stringByReplacingOccurrencesOfString:@"\n" withString:@""];
dataString = [dataString stringByReplacingOccurrencesOfString:@"  " withString:@""];
dataString = [dataString stringByReplacingOccurrencesOfString:@"\"" withString:@""];

start = [dataString rangeOfString:@"("];
end = [dataString rangeOfString:@")"];
NSString *arrayString = [dataString substringWithRange:NSMakeRange(start.location + 1, end.location - start.location - 1)];

NSArray *array = [arrayString componentsSeparatedByString:@","];
