SInvalidArgumentException ', 이유 :'- [NSArrayM objectForKey :] :

인덱스에있는 오브젝트가 실패하는 이유를 모르겠습니다. 나는 누군가가 이것을 바로 잡는 방법을 알고 있는지 궁금해하고 있었다. 실패한 특정 코드는 무효로드 이미지의 하단에 NSURL *imgURLLogo = [NSURL URLWithString:[[firstMessage objectForKey:@"message"] objectForKey:@"photo"]];입니다. 아무도 알아낼 수 없습니까?SInvalidArgumentException ', 이유 :'- [NSArrayM objectForKey :] :

지금 가지고있는 많은 코드 대신에 이것을 재현 가능한 샘플로 줄이는 것이 좋습니다. –

NSLog (@ "% @", firstMessage);를 실행하고 결과를 보여줍니다. 그 대답을 지시합니다. 분명히, 사전/배열의 구조는 예상 한 것과 다릅니다. – Rob

좋아, 나는 당신이 물어보고 출력을 게시했다. – moo

arrMessages가 마치이있는 NSArray의 배열이다. 따라서 arrMessages의 첫 번째 요소는 NSArray이 아니고 NSDictionary이 아닙니다.

혹시 이걸 고칠 수 있었는지 아십니까? – moo

objectsForContacts가 채워지는 곳을 선택하십시오. 이 코드에는 문제가없는 것 같습니다. – diederikh

NSMutableArray *arrMessages = [objectsForContacts objectForKey:[arrayOfUsers objectAtIndex:indexPath.row]];

objectsForContacts 란 무엇입니까? 배열 또는 사전입니까? 그것의 배열 인 경우, 그것이 잘못된 것입니다.
