RestKit 2级对象映射

Question

我将尝试解释我希望如何完成映射：

TOP lvl json 对象包含 Players 对象，它是 Player 对象的数组 每个Player 对象都包含一个数组，我希望数组中的每个对象都属于Event 对象（自定义对象）。

现在，由于我有 Player 对象的映射并且我正在填充数组，而不是 Event 对象（这是我想要的），我得到了 NSDictionary 对象。问题是我确实有我的Event 类的映射。我的问题是让 RestKit 将它们映射到数组中。 我尝试添加 Event 类的 responseDescriptors，但我没有运气。

这里是Player对象映射

 RKObjectMapping* playerMapping = [RKObjectMapping mappingForClass:[Player class]];
    [playerMapping addAttributeMappingsFromDictionary:@{
                                        ...more here              
                                           @"activeEvents" : @"activeEvents"
                                                         }];

这里是请求方法

 NSURL *taskURL = [NSURL URLWithString:kAppWebApiURLPath];

    // Set object manager with base url
    RKObjectManager *objectManager = [RKObjectManager sharedManager];
    objectManager = [RKObjectManager managerWithBaseURL:taskURL];
    objectManager.requestSerializationMIMEType = RKMIMETypeJSON;

    [objectManager.HTTPClient setDefaultHeader:@"Authorization" value:kAppWebAPIKey];
    [objectManager.HTTPClient setDefaultHeader:@"Content-Type" value:@"application/json"];

RKRequestDescriptor * requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[MappingProvider inverseLoginMapping]  objectClass:[LoginInfo class] rootKeyPath:nil method:RKRequestMethodPOST];

[objectManager addRequestDescriptor:requestDescriptor];

RKResponseDescriptor *playersResponseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[MappingProvider playerMapping] method:RKRequestMethodGET pathPattern:nil keyPath:@"players" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

[objectManager addResponseDescriptor:playersResponseDescriptor];

NSLog(@"%@",loginInfo.iOSDeviceToken);
[objectManager postObject:loginInfo path:kAppWebApiLoginPath parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult)
 {}...

更新，我现在需要更进一步的映射，我的播放器对象包含我使用成功映射的事件数组

[playerMapping addRelationshipMappingWithSourceKeyPath:@"activeEvents" mapping:[MappingProvider eventMapping]];

然而现在每个 Event 对象都包含一个 Player 数组，所以它就像 Players -> Events -> Players。

这是 Event 和 Player 对象的映射：

RKObjectMapping* eventMapping = [RKObjectMapping mappingForClass:[Event class]];

    [eventMapping addAttributeMappingsFromDictionary:@{

              @"stuffhere" : @"stuffz"                              
                                                       }];


    RKObjectMapping* playerMapping = [RKObjectMapping mappingForClass:[Player class]];
    [playerMapping addAttributeMappingsFromDictionary:@{
                                                        @"name": @"name",
                                                        @"activeEvents" : @"activeEvents"
                                                        }];
    [eventMapping addRelationshipMappingWithSourceKeyPath:@"activeEvents/players" mapping:playerMapping];

现在我没有得到递归函数，但是我如何在代码中声明以建立这种关系 json 数组的映射以分配给我的本地数组属性？

从映射中删除 @"activeEvents" : @"activeEvents" 并将其替换为：

[playerMapping addRelationshipMappingWithSourceKeyPath:@"activeEvents" mapping:eventMapping];

您还应该只有一个响应描述符，因为数据是嵌套的。
