Ios 带XML的RestKit-将代码转换为0.20

对于RestKit 0.20，以下代码的等效语法是什么

RKObjectMapping *atozMapping = [RKObjectMapping mappingForClass:[Atoz class]];
[atozMapping mapKeyPath:@"" toAttribute:@"city"];

RKObjectMapping *genreMapping = [RKObjectMapping mappingForClass:[Genres class]];
[genreMapping mapKeyPath:@"" toAttribute:@"genre"];

RKObjectMapping *stationSearchMapping = [RKObjectMapping mappingForClass:[StationSearchData class]];
[stationSearchMapping mapKeyPathsToAttributes:@"location", @"location", @"city", @"city", @"latitude", @"latitude", @"longitude", @"longitude", nil];
[stationSearchMapping mapKeyPath:@"browseatoz.atoz" toRelationship:@"browseAtozArray" withMapping:atozMapping];
[stationSearchMapping mapKeyPath:@"genres.genre" toRelationship:@"genreArray" withMapping:genreMapping];

[stationMapping mapRelationship:@"stationSearchData" withMapping:stationSearchMapping];
[stationManager.mappingProvider setMapping:stationSearchMapping forKeyPath:@"stationSearchData"];

以下是我尝试过的，但它似乎没有正确加载browseAtozArray（city为空）和genreArray（流派为空）：

RKObjectMapping *atozMapping = [RKObjectMapping mappingForClass:[Atoz class]];
[atozMapping addAttributeMappingsFromDictionary:@{
                                                      @"": @"city",
                                                      }];

RKObjectMapping *genreMapping = [RKObjectMapping mappingForClass:[Genres class]];
[genreMapping addAttributeMappingsFromDictionary:@{
                                                  @"": @"genre",
                                                  }];

RKObjectMapping *stationSearchMapping = [RKObjectMapping mappingForClass:[StationSearchData class]];
[stationSearchMapping addAttributeMappingsFromDictionary:@{
                                                  @"location.text": @"location",
                                                  @"city.text": @"city",
                                                  @"latitude.text": @"latitude",
                                                  @"longitude.text": @"longitude"
                                                  }];
RKRelationshipMapping* relationShipatozMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"browseatoz.atoz" toKeyPath:@"browseAtozArray" withMapping:atozMapping];
[stationSearchMapping addPropertyMapping:relationShipatozMapping];
RKRelationshipMapping* relationShipGenresMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"genres.genre" toKeyPath:@"genreArray" withMapping:genreMapping];
[stationSearchMapping addPropertyMapping:relationShipGenresMapping];

[stationMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"stationSearchData" toKeyPath:@"stationSearchData" withMapping:stationSearchMapping]];

[stationManager addResponseDescriptor: [RKResponseDescriptor responseDescriptorWithMapping:stationSearchMapping method:RKRequestMethodGET pathPattern:nil keyPath:@"stationSearchData" statusCodes:[NSIndexSet indexSetWithIndex:200]]];

下面是相关的XML：

<stationSearchData>
   <location>
  <![CDATA[ 79605 ]]>
 </location>
 <city>
  <![CDATA[ Abilene ]]>
 </city>
 <latitude>
  <![CDATA[ 32.43892288 ]]>
 </latitude>
 <longitude>
  <![CDATA[ -99.77902222 ]]>
 </longitude>
 <browseatoz>
  <atoz>
   <![CDATA[ Abilene ]]>
  </atoz>
  <atoz>
   <![CDATA[ Texas ]]>
  </atoz>
 </browseatoz>
 <genres>
  <genre>
   <![CDATA[ Rock ]]>
  </genre>
 </genres>
 <personalities/>
</stationSearchData>

我不太会使用XML，但会尝试使用无键路径映射：

[genreMapping addPropertyMapping:[RKAttributeMapping attributeMappingFromKeyPath:nil toKeyPath:@"genre"]];

谢谢你，韦恩。这让我更进一步了，但现在我看到了一些关于这些值的消息，如：E restkit.object_mapping:RKMappingOperation.m:440将keyPath'（null）处的值转换为'NSString'类型的表示失败：Error Domain=org.restkit.RKValueTransformers.ErrorDomain Code=3002“值转换失败”{text=Abilene；}'到NSString：咨询的2个值转换器均未成功。“UserInfo=0x15af2970{detailedErrors=（“Error Domain=org.restkit.RKValueTransformers.ErrorDomain Code=3002\”给定的值还不是一个…我想我需要将“.text”应用到nil键路径，有什么想法吗？像这样？[genreMapping addPropertyMapping:[RKAttributeMapping attributeMappingFromKeyPath:@“@text”toKeyPath:@“流派”]；当我将其更改为该选项时，它会崩溃。呜呜，它现在可以工作了：[genreMapping addPropertyMapping:[RKAttributeMapping attributeMappingFromKeyPath:@“text”toKeyPath:@“流派”]；忘了为此感谢您了..所以谢谢您！没有太多关于最新RestKit和解析XML的信息。
