Restkit возвращающий массив объектов с 0 ключевыми парами значений

Question

Я не уверен, что мне здесь не хватает. Для этого запроса я получаю ответ JSON с ключом «data.file». Дескриптор ответа установка таким образом:

[fileMapping addAttributeMappingsFromDictionary:@{@"parentPath" : @"parentPath"}]; 

RKResponseDescriptor *fileResponseDescriptorFile = 
    [RKResponseDescriptor responseDescriptorWithMapping:fileMapping 
        method:RKRequestMethodAny 
       pathPattern:nil 
        keyPath:@"data.file" 
       statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; 

Блок успеха getObjectsAtPath вызова обжигает, а оттуда отображение results.array показывает массив объектов, но без каких-либо ключевых пар значений.

Если я вручную десериализации JSON я получаю пары ключ-значение правильно заселенные.

NSDictionary* json = [NSJSONSerialization JSONObjectWithData:operation.HTTPRequestOperation.responseData options:NSJSONReadingMutableContainers error:nil]; 
     NSDictionary *data=[json objectForKey:@"data"]; 
     NSArray *files = [data objectForKey:@"file"]; 
     NSLog(@"files: %@", files); 

Вот отрывок из JSON:

    "folder": [

      "parentPath": "xxx", 
      "name": "xxx",

Это то, что отладчик показывает перед [[RKObjectRequestOperation responseMappingQueue] addOperation: self.responseMapperOperation] ;

Answer 1

Может быть, вы еще не добавили дескриптор к менеджеру объекта:

[objectManager addResponseDescriptor:responseDescriptor];
