iOS : 개체 개수 (0)가 키 수와 다릅니다

무엇이 잘못되었는지 전혀 알지 못하는 문제에 직면했습니다. 정보를 NSUserDefaults에 저장 한 다음이를 검색하는 다른 방법을 저장하는 방법이 있습니다. 나는 그것을 검색 할 때 오류 메시지가 와서 :iOS : 개체 개수 (0)가 키 수와 다릅니다

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

내 절약 방법은 다음과 같습니다

    return YES;

else

    return NO;

}

내 검색 중 방법은 다음과 같습니다

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

그리고 마지막 줄에

경고가 나온 곳입니다. 그 일이 왜 일어 났는지에 대한 어떤 생각?

도움말!

전체 스택 추적을 표시하십시오. unarchiver가 오류를 발생 시킨다는 말씀입니까? – Wain

예, 저장된 NSData의 보관을 시도한 위 코드의 마지막 줄은 오류가 발생한 곳입니다. – Marcus

이 시도,

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

희망 :

이는 "newDataToBeStored"의 상태 변수를 이전 NSUserDefaults에 저장하기에 .

나는 실수로 생각하고있다. for 루프 안에서 NSMutableDictionary * newIndividualPost = [individualPost mutableCopy];은 새롭고 새로운 객체를 만들지 않고 individualPost dictionary 사본을 만들고 다시 같은 객체를 반복해서 삽입한다는 의미이므로 사전을 인스턴스화한다고 생각한다. 따라서 NSMutableDictionary * newIndividualPost = [individualPost mutableCopy];을 NSMutableDictionary * newIndividualPost = [NSMutableDictionary new];으로 바꾸면 제대로 작동합니다.

'NSDictionary * d1 = @ {@ "key": @ "value"}; NSMutableDictionary * d2 = [d1 mutableCopy]; d2 [@ "key"] = d1 [@ "key"];'d2' * still *은 하나의 키와 하나의 값을가집니다. 덮어 씁니다. 기본적으로 할당 후 'd2'는 할당 이전과 동일합니다. 그래서 그것은 오류의 이유가 될 수 없습니다. – FreeNickname

@iHulk 귀하의 제안을 시도했지만 여전히 같은 오류가 나타납니다. – Marcus

@FreeNickname 그래서 당신의 제안은 무엇입니까? – Marcus

UIImage * coverImage = [UIImage imageWithCGImage : coverImageConverted.CGImage 스케일 : coverImageConverted.scale orientation : coverImageConverted.imageOrientation]; – user5336298

iOS : 개체 개수 (0)가 키 수와 다릅니다
