我一直在努力处理这种关系连接。使用addConnectionForRelationship的RestKit 0.24映射
数据模型
我有以下JSON：

的AOThreadMessage螺纹关系是零。其他关系正确设置。
<AOThreadMessage: 0x7fa529a694d0> (entity: AOThreadMessage; id:
0xd00000000004001c <x-coredata://23C60BAE-57BD-4904-BF7B-7D550DE13190/AOThreadMessage/p1> ; data: {
address = nil;
media = nil;
messageId = 20;
participantId = 106;
status = "";
text = test;
thread = nil;
timestamp = "2015-02-03 13:20:33 +0000";
})

我已经编辑了数据模型和修改实体映射定义的问题。现在没有设置AOThreadMessage线程关系。除此之外，关系正确设置。无法弄清楚问题所在。关于使用路径模式确实是件好事。我会执行这个。让我知道基于模型，如果关系正确完成（我认为是这样，但谁知道:)） – Appsido 2015-02-03 13:30:44
模型看起来不错。原始日志显示正在连接的消息。如果它们没有被使用，你需要摆脱所有其他的响应描述符 - 你只需要一个响应描述符来映射线程及其所有嵌套的内容。 – Wain 2015-02-03 14:51:53
事实上，在我根据您的评论修改映射之前，原始日志显示了问题。我已经编辑了所有的儿子/映射定义。除非消息>线程关系没有完成，否则任何事情都可以。更具体地说，当我第一次从API获取线程的所有链接。但是，如果在给定的线程中发布消息（请参阅编辑的json），则消息不会链接到线程。关于响应描述符，由于消息描述符位于@“response.messages”而不是@“response.threads.messages”上，因此它们不会被考虑在内。 – Appsido 2015-02-03 16:19:15
