Ios RestKit:“；multipartFormRequestWithObject“；仅发送附件，对象属性丢失

我需要发布一个带有图像的Realty对象：

-(void) addRealty:(Realty*)realty withImages:(NSDictionary*)images success:(void (^)(Realty *))callback failure:(void(^)(void))failure
{
   UIImage *image = [UIImage imageNamed:@"test.png"];

   NSMutableURLRequest *request = [_httpClient multipartFormRequestWithObject:realty method:RKRequestMethodPOST path:@"/realties.json" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:UIImagePNGRepresentation(image)
                                        name:@"_realty[images][0]"
                                    fileName:@"test.png"
                                    mimeType:@"image/png"];
        }];

        RKObjectRequestOperation *operation = [_httpClient objectRequestOperationWithRequest:request success:nil failure:nil];
        [_httpClient enqueueObjectRequestOperation:operation];
    }
}

您必须为Realty添加RKRequestDescriptor对象

RKObjectMapping* realtyMapping = <...>;
RKRequestDescriptor* reqDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:realtyMapping
objectClass:[Realty class]
rootKeyPath:nil
method:RKRequestMethodAny];
[[RKObjectManager sharedManager] addRequestDescriptor:reqDescriptor];

RKObjectMapping*realtyMapping=；
RKRequestDescriptor*reqDescriptor=[RKRequestDescriptor RequestDescriptor WithMapping:realtyMapping
objectClass:[不动产类]
rootKeyPath:nil
方法：RKRequestMethodAny]；
[[RKObjectManager sharedManager]addRequestDescriptor:reqDescriptor]；

祝您好运：）

您可能需要使用

[realtyMapping inverseMapping]

RKObjectMapping *realtyMapping = [RKObjectMapping mappingForClass:[Realty class]];
[realtyMapping addAttributeMappingsFromArray: @[@"_id",@"user_id",@"description",@"notes",@"address",@"coords",@"pictures",@"area",@"rtype",@"rooms",@"price",@"price_m",@"title"]];

// - multiple
RKResponseDescriptor *realtiesDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:realtyMapping method:RKRequestMethodAny pathPattern:nil keyPath:@"realties" statusCodes:statusCodes];
[_httpClient addResponseDescriptor:realtiesDescriptor];
// - single
RKResponseDescriptor *realtySingleDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:realtyMapping method:RKRequestMethodAny pathPattern:nil keyPath:@"realty" statusCodes:statusCodes];
[_httpClient addResponseDescriptor:realtySingleDescriptor];

RKObjectMapping* realtyMapping = <...>;
RKRequestDescriptor* reqDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:realtyMapping
objectClass:[Realty class]
rootKeyPath:nil
method:RKRequestMethodAny];
[[RKObjectManager sharedManager] addRequestDescriptor:reqDescriptor];
