간단한 푸시 UIStoryboardSegue가 실패하는 이유는 무엇입니까?

Question

UIStoryboardSegue, NSException 응용 프로그램에는 약 25 개의 viewController가있는 스토리 보드가 있습니다. 모든 단서는이 것을 제외하고는 모두 작동합니다. 이것은 애플리케이션이 종료 댈러스 제외하고 엑스 코드 5.1

EditRecipeViewController에서 Segue 식별자가있는 AddPhotoViewController로 푸시 segue가 있습니다. EDIT_RECIPE_ADDPHOTO AddPhotoVC의 모든 메소드 상단에 NSLog가 있습니다. Exception 전에 두 개만 인쇄됩니다.

1. viewWillAppear에서의 viewDidLoad
2. 에서 송신자 :

   else if([segue.identifier isEqualToString:@"EDIT_RECIPE_ADDPHOTO"]){ 
        AddPhotoViewController *destCntrlr = (AddPhotoViewController*)segue.destinationViewController; 
        Photo* aPhoto = [NSEntityDescription insertNewObjectForEntityForName:@"Photo" inManagedObjectContext:self.recipe.managedObjectContext]; //INSERT MO 
        [self setPhoto:aPhoto]; 
        DLog(@"INSERT:self.photo=%@",self.photo); 
         //NEED indexPath NOW 
        NSIndexPath *indexPath= (NSIndexPath *)sender; 
        [[self photo] setSortIndex:[NSNumber numberWithInt:indexPath.row]]; 
        NSString* stockName = [NSString stringWithFormat:@"Photo #%u", [indexPath indexAtPosition:1] + 1]; 
        [[self photo] setName:stockName]; 
        [[self photo] setModified:[NSDate date]]; 
        [[ self photo] setUid:[Photo calculateNewUniqueID]]; 
        [destCntrlr setPhoto:aPhoto]; 
        [destCntrlr setDelegate:self]; 
        [destCntrlr setRecipe:[self recipe]]; 
        DLog(@"End EDIT_RECIPE_ADDPHOTO Prepare"); 
   } 
   

   [self performSegueWithIdentifier:@"EDIT_RECIPE_ADDPHOTO" sender:indexPath]; 
   

   가 -prepareSegue이 코드 다음 :

SEGUE는 EditRecipeViewController에 사용 시도

AddPhoto보기가 나타나지 않습니다. AddRecipe 초기 장면 []의 상자를 선택하면 초기보기 컨트롤러이며 시작시보기가 올바르게 표시됩니다. NIB 파일을 사용하여 AddPhoto보기를 표시 할 수도 있습니다.

UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"AddPhotoID"]; 
[self presentViewController:vc animated:YES completion:nil]; 

내가이 스토리 보드/SEGUE의 문제에 대한 해결책을 추적하기 위해 무슨 짓을 : 나는 또한 사용하여 AddPhotoViewController을 넣을 수 있습니다? 내 코드에서 인스턴스에 대한

• 확인 [은 insertObject : atIndex :]

• 에 모든 예외 중단 점, [ NSArrary은 insertObject : atIndex :] 나는이 중단 점은 응용 프로그램을 중지하고 나는 문제를 찾기 위해 통과 할 수있는 스택을 표시 할 것으로 예상 모든 모듈

합니다. 난 단지 참조 :

나는 날이 예외에 대한 해결책을 추적 할 수 있도록 로그 메시지를 찾을 수 없습니다. 디버그 로그를보고 있지만 예외에 대한 유용한 참조가 없습니다. 결국 위에 나열된 것만 볼 수 있습니다. 도와주세요. 읽기

내가 검색

@property(nonatomic, strong) Photo* photo; 

(포함, 위해 사례 무시 : 배열) 전체 destinationController 구현 파일, 즉 AddPhotoViewController.m을. 이 검색에서 어디에도 결과가 없습니다.

그래서 비슷한 문제에 대한 다음 답을 찾았습니다.

This is a fairly common error and it has three causes: 

Misspelling the entity name e.g. NewsStand instead of NewsStands. 
Having a nil managed object context 
Having no or the wrong managed object model loaded. 
(1) is the most common but (3) is more common than (2). You can check that you are loading the right model with the keypath: 

aManagedObjectContext.persistentStoreCoordinator.managedObjectModel.entities 
then check the entity's names. 

AddPhotoViewController는 NSManagedObjectContext 또는 NSManagedObjectModel 중 하나에 대한 더 바르가 없습니다. 엔티티 이름의 철자가 "Photo"입니다. 대한 던져 설정 기호 브레이크 포인트에, 모든 예외 브레이크 포인트를 설정 캐치 에

1. Home (RootTableViewController) TV shows list of Recipe categories. 
2. Selection of category on RTVC -> display SubListViewController (list of Rxs for the category) 
3. Touch Edit button to reach Edit Recipe Mode, which includes display of '+' button to reach

4. User is force to enter Name of Rx before proceeding. 
5. I then touch Add Photo button -> (AddPhotoVC) for this new Recipe object and the problems ensue.

Answer 1

바보 ViewController에 NavigationItem을 추가했습니다!

Apple Developer Tech Support에서 TSI로 바꾸어서 알게되었습니다.

기술 썼다 :

이보기 컨트롤러 다시를 상속 AddPhotoViewController.m

그래서

@synthesize navigationItem; 

에서이 줄뿐만 아니라 AddPhotoViewController.h

에서

@property(nonatomic, retain) UINavigationItem* navigationItem; 

을이 줄을 제거 표준 행동.
