RestKitを使用してJSONをコアデータにマッピングできません。RKロギングは次のように言っています：

Did not find mappable relationship value keyPath.

私は明らかに何か間違ったことをしています。

       }

}

これが私のマッピングです：

objectManager.objectStore = [RKManagedObjectStore objectStoreWithStoreFilename:@"AppCD.sqlite"];

RKManagedObjectMapping* entityClassItemValueMapping = [RKManagedObjectMapping mappingForClass:[EntityClassItemValue class] inManagedObjectStore:[[RKObjectManager sharedManager] objectStore]];
entityClassItemValueMapping.primaryKeyAttribute = @"name";
[entityClassItemValueMapping mapKeyPath:@"NAME" toAttribute:@"name"];
[entityClassItemValueMapping mapKeyPath:@"VALUE" toAttribute:@"value"];

RKManagedObjectMapping* entityClassItemMapping = [RKManagedObjectMapping mappingForClass:[EntityClassItem class] inManagedObjectStore:[[RKObjectManager sharedManager] objectStore]];
entityClassItemMapping.primaryKeyAttribute = @"iqid";
[entityClassItemMapping mapKeyPath:@"IQID" toAttribute:@"iqid"];

RKManagedObjectMapping* entityClassMapping = [RKManagedObjectMapping mappingForClass:[EntityClass class] inManagedObjectStore:[[RKObjectManager sharedManager] objectStore]];
entityClassMapping.primaryKeyAttribute = @"type";
[entityClassMapping mapKeyPath:@"OBJECTCLASS" toAttribute:@"type"];
[entityClassMapping mapKeyPath:@"TIMESTAMP" toAttribute:@"timestamp"];

[entityClassMapping mapKeyPath:@"VALUES" toRelationship:@"values" withMapping:entityClassItemMapping];
[entityClassItemMapping mapKeyPath:@"DATA" toRelationship:@"entityClassItemValues" withMapping:entityClassItemValueMapping];

[[RKObjectManager sharedManager].mappingProvider setMapping:entityClassMapping forKeyPath:@"JSONDATA"];
[[RKObjectManager sharedManager].mappingProvider setMapping:entityClassItemMapping forKeyPath:@"VALUES"];
[[RKObjectManager sharedManager].mappingProvider setMapping:entityClassItemValueMapping forKeyPath:@"DATA"];

[[objectManager client] setValue:[cookies objectForKey:@"Cookie"] forHTTPHeaderField:@"Cookie"];
NSDictionary *params = [[NSDictionary alloc] initWithObjectsAndKeys:query, @"Targ", @"", @"Query", @"F285E67F2C8CEC9837B68", @"$SESSION", @"3A7037FA806156C4", @"VERSION", nil];
[objectManager loadObjectsAtResourcePath:URL_DATA usingBlock:^(RKObjectLoader *loader) {
    loader.method = RKRequestMethodPOST;
    loader.params = params;
    loader.mappingProvider = [RKObjectManager sharedManager].mappingProvider;
    loader.onDidLoadObjects = loadBlock;
    loader.onDidFailWithError = failBlock;
}];

私のCoreDataモデルは次のとおりです。

#import <Foundation/Foundation.h>
#import <CoreData/CoreData.h>

@class EntityClassItem;

@interface EntityClass : NSManagedObject

@property (nonatomic, retain) NSString * timestamp;
@property (nonatomic, retain) NSString * type;
@property (nonatomic, retain) NSSet *values;
@end

@interface EntityClass (CoreDataGeneratedAccessors)

- (void)addValuesObject:(EntityClassItem *)value;
- (void)removeValuesObject:(EntityClassItem *)value;
- (void)addValues:(NSSet *)values;
- (void)removeValues:(NSSet *)values;

#import <Foundation/Foundation.h>
#import <CoreData/CoreData.h>

@class EntityClassItem;

@interface EntityClass : NSManagedObject

@property (nonatomic, retain) NSString * timestamp;
@property (nonatomic, retain) NSString * type;
@property (nonatomic, retain) NSSet *values;
@end

@interface EntityClass (CoreDataGeneratedAccessors)

- (void)addValuesObject:(EntityClassItem *)value;
- (void)removeValuesObject:(EntityClassItem *)value;
- (void)addValues:(NSSet *)values;
- (void)removeValues:(NSSet *)values;

#import <Foundation/Foundation.h>
#import <CoreData/CoreData.h>

@class EntityClassItem;

@interface EntityClassItemValue : NSManagedObject

@property (nonatomic, retain) NSString * name;
@property (nonatomic, retain) NSString * value;
@property (nonatomic, retain) EntityClassItem *entityClassItem;

たくさんのデバッグとドキュメントの再読の後でそれを理解しました。それは私の周りの理解の欠如でした：

mapKeyPath:@"foo" toRelationship:@"bar" withMapping:fooBar];

ドキュメントに明確に記載されているように、mapKeyPathは、JSONペイロードのノードに加えて、マッピング先のオブジェクトのプロパティの両方と一致する必要があります。ペイロードのケースが一致しなかったため、失敗していました。
