Ios RESTKIT 0.22设备上的CoreData问题

我对restkit映射到CoreData有一个奇怪的问题。所有这些都可以在模拟器中正常工作，但在真实设备中却不行。成功请求服务器后，两种情况下的结果映射都是成功的（我可以访问RkmapingResult*mappingResult中的每个值）。新值存储在模拟器中，但不存储在设备中。我用谷歌搜索了很多次，但没有找到解决办法

我不这样做：

RKObjectMapping *requestMapping =  [[hcUpdateRequest defineUpdateRequestMapping] inverseMapping];

[self.objectManager addRequestDescriptor: [RKRequestDescriptor requestDescriptorWithMapping:requestMapping objectClass:[hcUpdateRequest class] rootKeyPath:nil method:RKRequestMethodPOST]];

RKEntityMapping *storyMapping = [hcUpdateResponse storyMapping:self.objectManager.managedObjectStore];
{..moreMapping..}


[storyMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"pieces" toKeyPath:@"pieces" withMapping:pieceMapping]];
{..moreMapping..}


[self.objectManager setRequestSerializationMIMEType: RKMIMETypeFormURLEncoded];

[self.objectManager postObject:self.dataUpdateRequst
                          path:@"storyAll"
                    parameters:nil
                       success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {…}


+ (RKEntityMapping*) storyMapping:(RKManagedObjectStore*)managedObjectStore {

    RKEntityMapping* storyMapping = [RKEntityMapping mappingForEntityForName:@"Story" inManagedObjectStore:managedObjectStore];
    [storyMapping addAttributeMappingsFromDictionary:@{
                                                       @"id":@"idRemoteDatabase",
                                                       @"name":@"name",
                                                       @"position_x": @"positionX",
                                                       @"position_y": @"positionY",
                                                       @"state": @"state",
                                                       @"gender": @"gender"
                                                       }];
    storyMapping.identificationAttributes = @[@"idRemoteDatabase"];
    return storyMapping;

}

那么，手机和sim卡有什么区别呢？测试是否显示发送和接收相同的请求和响应？存储在哪里？映射并没有揭示很多关于您的问题。是的，模拟器和设备显示相同的结果。请求和响应是相同的。唯一的区别是接收到的数据并没有存储在设备上的CoreData中。到哪里去找问题？当我以编程方式推送CoreData时，CoreData在设备上运行良好。打开跟踪日志记录，显示核心数据堆栈设置的代码。问题在于对象管理器NSString*路径的初始化=[RKApplicationDataDirectory（）stringByAppendingPathComponent:@“CoreData.sqlite”]；[self.objectManager.managedObjectStore addSQLitePersistentStoreAtPath:path fromseddatabaseatpath:nil with configuration:nil选项：nil错误：&error]；[self.objectManager.managedObjectStore createManagedObjectContexts]；什么问题？你能详细描述一下吗？
