Restkit "***でアサーション失敗 - [RKManagedObjectMapping initWithEntity：]" 私は、実行時に、このアサーションの失敗を取得しています

Question

初期化Restkitは：

// RestKit 
#import <RestKit/RestKit.h> 
#import <RestKit/CoreData/CoreData.h> 
#import <RestKit/Support/JSON/JSONKit/RKJSONParserJSONKit.h> 
#import "DBManagedObjectCache.h" 
#import "DBUser.h" 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
... 
RKLogDebug(@"Initializing Restkit..."); 


RKObjectManager* objectManager = [RKObjectManager objectManagerWithBaseURL:@"http://localhost:8888"]; 
//objectManager.router = [[RKDynamicRouter new] autorelease]; 
//manager.router = router; 

objectManager.objectStore = [[[RKManagedObjectStore alloc] initWithStoreFilename:@"mydb.sqlite"] autorelease]; 
objectManager.objectStore.managedObjectCache = [[DBManagedObjectCache new] autorelease]; 

RKLogDebug(@"Begining object mapping..."); 
RKManagedObjectMapping* userMapping = [RKManagedObjectMapping mappingForClass:[DBUser class]]; 
RKLogDebug(@"Begining object mapping... 1"); 
userMapping.primaryKeyAttribute = @"userID"; 
userMapping.setDefaultValueForMissingAttributes = YES; // clear out any missing attributes (token on logout) 

... 
}

これはコードです

これはRKManagedObjectMapping.mで失敗するところです：

- (id)initWithEntity:(NSEntityDescription*)entity { 
NSAssert(entity, @"Cannot initialize an RKManagedObjectMapping without an entity. Maybe you want RKObjectMapping instead?"); 
... 

どのようなアイデアですか？ありがとう!!!! kky

Answer 1

ありがとうtegbains、あたりとしてマッピングオブジェクト必要があります:)

Answer 2

あなたはCoreDataを使用していないと思います。あなたはRKObjectMappingと関連する非管理対象オブジェクトを使用することを検討し、実際に問題がDataModel.xcdatamodelでエンティティDBUSERを作成して解決するものrestkitの概要については、このTutorial
