어떻게하면 NSInternalInconsistencyException을 해결할 수 있습니까? ', reason :'+ entityForName : 실패한 보고서

Question

내 코드는 다음과 같습니다.

NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext]; 
     NSEntityDescription *entity = [[self.fetchedResultsController fetchRequest] entity]; 
     NSManagedObject *newManagedObject = [NSEntityDescription insertNewObjectForEntityForName:[entity name] inManagedObjectContext:context]; 

     // If appropriate, configure the new managed object. 
     [newManagedObject setValue:[NSDate date] forKey:@"date"]; 

      // Save the context. 
      NSError *error = nil; 
      if (![context save:&error]) { 
       NSLog(@"Unresolved error %@, %@", error, [error userInfo]); 
       abort(); 
     } 

.h .h .h 헤더 파일에 있습니다.

@interface TretiViewController : UIViewController <NSFetchedResultsControllerDelegate> { 

NSFetchedResultsController *fetchedResultsController_; 
    NSManagedObjectContext *managedObjectContext_; 

// private NSString *accountID; 
} 


@property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; 
@property (nonatomic, retain) NSFetchedResultsController *fetchedResultsController; 

코어 데이터를 사용하여 데이터를 저장해야하지만 오류가 발생합니다.

- (NSFetchedResultsController *)fetchedResultsController { 

    if (fetchedResultsController_ != nil) {

    } 


    // Set up the fetched results controller. 

    // Create the fetch request for the entity.

    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Obrat" inManagedObjectContext:self.managedObjectContext];

    [fetchRequest release]; 
    [sortDescriptor release]; 
    [sortDescriptors release]; 

    NSError *error = nil; 
    if (![fetchedResultsController_ performFetch:&error]) { 

// Replace this implementation with code to handle the error appropriately. 

// abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button. 

    NSLog(@"Unresolved error %@, %@", error, [error userInfo]); 
    abort(); 
    } 

    return fetchedResultsController_; 
    }  

무엇이 누락 되었습니까?

Answer 1

변경 fetchedResultsController의 코드 :

NSEntityDescription *entity = [NSEntityDescription entityForName:@"Obrat" inManagedObjectContext:self.managedObjectContext]; 

당신은 내가 어떤 스레드를 발견

Answer 2

"Obrta"이라는 엔티티가 있지만이 코드는 "Obrat" 유형의 객체를 생성한다고합니다. 그 오타를 수정하면 문제가 해결됩니다.
