iOS: кол-во объектов (0) отличается от количества ключей

Question

Я столкнулся с проблемой, о которой я понятия не имею, что пошло не так. У меня есть метод для сохранения информации в NSUserDefaults, а затем еще один способ ее получения. Но когда я получить это сообщение об ошибке пришел:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSDictionary initWithObjects:forKeys:]: count of objects (0) differs from count of keys (19)'

     [storage synchronize]; 
    } 

    return YES; 

} 
else 
{ 

    return NO; 
} 
} 

Мой метод при получении является:

NSUserDefaults * storage = [NSUserDefaults standardUserDefaults]; 
NSDictionary * petsData = (NSDictionary*) [NSKeyedUnarchiver unarchiveObjectWithData:[storage objectForKey:@"PetPageBackup"]]; 

И в последней строке где появилось предупреждение. Любая идея о том, почему это произошло?

Помощь!

EDIT:

Это состояние "newDataToBeStored" переменной перед сохранением в NSUserDefaults:

Answer 1

Попробуйте это,

newIndividualPost = [[NSMutableDictionary alloc]initWithDictionary: individualPost]; 

надеюсь, что это решит вашу проблему ,

Answer 2

Я думаю, что вы делаете простую ошибку, внутри цикла for вы создаете свой словарь, поскольку NSMutableDictionary * newIndividualPost = [individualPost mutableCopy]; означает, что вы не создаете новый новый объект, а создаете копию своего individualPost dictionary и снова вставляете те же объекты снова и снова. Поэтому замените свою линию NSMutableDictionary * newIndividualPost = [individualPost mutableCopy]; на NSMutableDictionary * newIndividualPost = [NSMutableDictionary new];, и она будет работать.

Answer 3

//"ImageURLCover" 
if ([(NSString *)[individualPost objectForKey:@"ImageURLCover"] length] > 0) 
{ 
    NSData * coverImageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:(NSString *)[individualPost objectForKey:@"ImageURLCover"]]]; 
    UIImage * coverImageConverted = [UIImage imageWithData:coverImageData]; 
    if (coverImageConverted) 
{ 
    [newIndividualPost setObject:coverImageConverted forKey:@"ImageURLCover"]; 
} 
    else 
{ 
    [newIndividualPost setObject:[UIImage imageNamed:@"no_image.png"] forKey:@"ImageURLCover"]; 
} 
}
