Iphone Restkit 0.20对象在获得json响应后未映射

我正在使用RESTKit0.20。我试图从本地rails应用程序下载json响应，并将其保存到核心数据中。我试着跟随，一切都很顺利。
我想多次使用它，所以我将其作为基类（ListController）并将其子类化为SessionListController和EventListController。映射在AppDelegate.m中提供。

该应用程序有一个第一个viewcontroller，它是根控制器，始终映射响应，一切正常。但只要我更改viewcontroller，我就会得到响应，操作就会停止。它甚至没有说映射是否已经开始。我不确定我错过了什么

我在这里初始化restkit

AppDelegate.m SessionViewController.m 完整代码位于

使用后

RKLogConfigureByName("RestKit", RKLogLevelWarning);
RKLogConfigureByName("RestKit/ObjectMapping", RKLogLevelTrace);
RKLogConfigureByName("RestKit/Network", RKLogLevelTrace);

---

我可以看到，我得到了正确的Http响应，但它没有被映射。我不知道为什么？

我刚刚将我的Restkit包更新为0.20.2。我现在没有面对这个问题。它应该在更新中修复。

日志是否说有时找不到响应描述符？或者没有匹配的关键路径？需要一些日志或示例JSON进行比较。不，日志中没有任何错误消息。它只是在记录响应文本后停止。事件的json响应示例是listApiFor的代码：-它返回什么路径？listApiFor返回事件的api路径-返回@“/api/v1/events”和会话返回@“/api/v1/sessions”定义响应描述符时，指定不带前导“/”的路径模式。很奇怪的是，在跟踪登录时没有日志信息，通常它会准确地告诉您问题所在。
