ios - RestKit:一对多关系映射

Question

我正在尝试使用 RestKit 解析 github 的 gist api 响应。这是 json 的片段:

  {
    "url": "https://api.github.com/gists/6004248",
      ...
    "html_url": "https://gist.github.com/6004248",
    "files": {
      "ApplicationContext.h": {
        "filename": "ApplicationContext.h",
        "type": "text/plain",
        "language": "Objective-C",
        "raw_url": "https://gist.github.com/raw/6004248/4531c7534585b273c55ca71ce9020418b7ed271b/ApplicationContext.h",
        "size": 481
      },
      "ApplicationContext.m": {
        "filename": "ApplicationContext.m",
        "type": "text/plain",
        "language": "Objective-C",
        "raw_url": "https://gist.github.com/raw/6004248/27a3881f9c5adde700b75199076a5ce259d0b568/ApplicationContext.m",
        "size": 542
      }
    },
      ...
    "user": {
      ...
    },
    "comments_url": "https://api.github.com/gists/6004248/comments"
  },

一切正常，但我的文件关系有问题。这是负责文件的代码片段:

RKObjectMapping *gistMapping = [RKObjectMapping mappingForClass:[MBGist class]];
[gistMapping addAttributeMappingsFromDictionary: @{@"url": @"url", @"html_url": @"htmlUrl", @"description": @"description"}];

RKObjectMapping *fileMapping = [RKObjectMapping mappingForClass:[MBFile class]];
[fileMapping addAttributeMappingsFromDictionary:@{@"filename": @"filename", @"language": @"language", @"type":@"type"}];

[gistMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"files" toKeyPath:@"files" withMapping:fileMapping]];

但我的 MBGist 类对象中有空文件数组。

有人可以帮我吗？

最好的问候，迈克尔
