Objective c RestKit:注销时重置持久存储后映射的0个对象

在RestKit版本0.23.x上，我尝试在用户注销时重置core数据的持久存储，方法如下：

// Cancel all requests
[[RKObjectManager sharedManager] cancelAllObjectRequestOperationsWithMethod:RKRequestMethodAny matchingPathPattern:@"/"];

[[RKObjectManager sharedManager].operationQueue cancelAllOperations];

[RKObjectManager sharedManager].managedObjectStore.managedObjectCache = nil;

// Clear our object manager
[RKObjectManager setSharedManager:nil];

// Reset our persistent store
[[RKManagedObjectStore defaultStore] resetPersistentStores:nil];

// This command runs the reconfiguration of RestKit, the same
// code that is applied when the app launches.
[self setup] 

但是，当我重新登录时，RestKit无法映射响应：

2015-01-27 10:28:16.452 <APP_NAME>[80341:12445388] I restkit.network:RKObjectRequestOperation.m:220 GET '<api url>' (200 OK / 0 objects) [request=0.2098s mapping=0.0011s total=0.2112s]

我错过了什么

更多信息-通过跟踪日志记录级别，我可以看到服务器正确地返回数据，但它没有被映射。出于安全原因，数据被截断：

2015-01-27 17:32:03.773 <APP_NAME>[86020:12883038] T     restkit.network:RKObjectRequestOperation.m:218 GET '<api url>' (200 OK / 0 objects) [request=0.3788s mapping=0.0011s total=0.3802s]:

response.headers={
  Connection = "keep-alive";
  "Content-Length" = 342;
  "Content-Type" = "application/json; charset=utf-8";
  Date = "Tue, 27 Jan 2015 16:32:03 GMT";
  Etag = "\"-968344033\"";
  Vary = "Accept-Encoding";
  "X-Powered-By" = Express;
}
response.body={
  "status": "success",
  "data": { <--- truncated exactly one object --> }
}

另一编辑：

这个问题似乎只影响实体映射，而不是普通对象映射。登录步骤中有一个这样成功的映射。

看起来我把问题复杂化了。现在有一个解决方案适合我：

// Cancel any network operations and clear the cache
[[RKObjectManager sharedManager].operationQueue cancelAllOperations];
[[NSURLCache sharedURLCache] removeAllCachedResponses];

// Cancel any object mapping in the response mapping queue
[[RKObjectRequestOperation responseMappingQueue] cancelAllOperations];

// Reset persistent stores
[self.managedObjectStore resetPersistentStores:nil];

澄清一下：根本不需要将任何东西归零。

所以你将各种事情归零，但你什么时候重新创建它们呢？好问题！我应该更准确地说。暂时更新问题。之后是否仍设置所有RestKit值？我有相同的代码，但RestKit告诉我无法保存新登录用户的数据时出错：无法将托管对象上下文保存到持久存储。
