Question

我正在尝试提取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 =                                         (

                                        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）。我想提取＆＃34; Bedford Stuyvesant＆＃34;，Brooklyn＆＃34;例如，从上面的内容来看。已经尝试了很多方法，但是例如。将地标转换为NSDictionary失败。任何帮助将不胜感激！

也许你可以做一些字符串处理来从你的placemark.description中提取dependentLocality。但是你为什么不只使用placemark.subLocality属性？

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:@","];

从CLPlacemark项中提取dependentLocality
