以下のエラーが表示されます。何が間違っているのかわかりません。

見つからないマネージドオブジェクトもあると思いますが... alf !

 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '+entityForName: could not locate an NSManagedObjectModel for entity name 'Boxes''

ここに私の.mがあります(2つの主要な機能のみ)

    - (void)loadCoreData
{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"Test" object:self];
    context = [app managedObjectContext];
    NSError *err;

    // GET THE JSON
    NSString *urlString = [NSString stringWithFormat:@"http://localhost:8888/json.txt"];
    NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]]; 
    NSMutableArray *json = (NSMutableArray* )[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&err];
    // FILL THE ENTITY
    for (int i = 0; i != 7; i++)
    {
        Boxes *boxes = [NSEntityDescription insertNewObjectForEntityForName:@"Boxes" inManagedObjectContext:context];

        boxes.name =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"name"] ;
        boxes.sexe =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"sexe"] ;
        boxes.topic =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"topic"] ;
        boxes.number = [NSNumber numberWithInt:[[[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"number"] intValue]];
    }
    request = [[NSFetchRequest alloc] init];
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Boxes" inManagedObjectContext:context];
    [request setEntity:entity];    
    arrayForPredicate = [context executeFetchRequest:request error:&err];
}

- (void) fillSexArray:(NSString *)sexe
{

    // PREDICATE TO GET AN ARRAY OF PRODUCT WITH SEXE EQUAL TO 
    NSPredicate *sex;

    if ([sexe isEqualToString:@"both"])
    {
        sex = [NSPredicate predicateWithFormat:@"sexe = %@ OR sexe = %@", @"female", @"male"];
    }
    else
    {
        sex = [NSPredicate predicateWithFormat:@"sexe = %@", sexe];
    }
    NSArray  *BoxWithSex = [arrayForPredicate filteredArrayUsingPredicate:sex];
    NSMutableArray *mutableArray = [self createMutableArray:BoxWithSex];    
    //  NSLog(@"%@", [[mutableArray objectAtIndex:1] valueForKey:@"name"]);
  //  NSUInteger numObjects = [mutableArray count];


}

私の .h :

@interface AddViewController : UIViewController

{

IBOutlet UIButton *male;
IBOutlet UIButton *female;
IBOutlet UIButton *couple;
UIButton *maleBtn;
BOOL flag;
NSArray *arrayForPredicate;
NSFetchedResultsController *fetchedResultsController;
NSManagedObjectContext *context;
NSFetchRequest *request;

}

@property (nonatomic, retain) WonderAppDelegate *app;
- (void) fillSexArray:(NSString *)sexe;
- (NSMutableArray *)createMutableArray:(NSArray *)array;
- (void)loadCoreData;
- (void)sexeButtonPressed;
- (void)sexeArray;
@end

managedObject を作成する編集:

+ (id)boxWithDictionary:(NSDictionary *)dict withManagedObjectContext:(NSManagedObjectContext *)managedObjectContext;
{
    Boxes *boxes = [NSEntityDescription insertNewObjectForEntityForName:@"Boxes" 
                                             inManagedObjectContext:managedObjectContext];

    boxes.name    = [dict objectForKey:@"name"];
    boxes.sexe    = [dict objectForKey:@"sexe"];
    boxes.topic    = [dict objectForKey:@"topic"];
    boxes.number   = [dict objectForKey:@"number"];

    return boxes;
}

これは私の.mであり、そのように機能していますが、関数のコードは必要ありません。そこに追加したいのですが、loadCoreDataに追加します。

永続ストアの作成後にモデルを更新しましたか? シミュレーター (またはデータベース ファイル) からアプリを削除して、もう一度実行してみてください。
