[iOS Error] UICollectionView ReusableView 에러

안녕하세요 Foma 💻 입니다!

 

오늘 만난 에러는 바로 위와 같이 'NSInternalInconsistencyException' 오류 였습니다.

 

 

이게 무슨 말이냐면 컬렉션뷰에서 ReusableView를 사용했는데 dequeReusableCell로 보통과 같이 세팅했기 때문입니다.

 

제 코드를 보면 아래와 같이 컬렉션뷰 헤더와 푸터를 ReusableView로 만들어서 세팅했는데요.

 

아래와 같이 deque하는 부분이 일반 셀과 같이 dequeReusableCell로 되어있습니다.

 

  func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView {
        if kind == UICollectionView.elementKindSectionHeader{
            let cell = collection.dequeueReusableCell(withReuseIdentifier: "VoiceChatCreateHeaderCollectionViewCell", for: indexPath) as! VoiceChatCreateHeaderCollectionViewCell
            cell.bind(reactor: reactor)
            return cell
        }else {
            let cell = collection.dequeueReusableCell(withReuseIdentifier: "VoiceChatCreateFooterCollectionViewCell", for: indexPath) as! VoiceChatCreateFooterCollectionViewCell
            cell.bind(reactor: reactor)
            return cell
        }
    }

 

해결법은 아래와 같이 dequeReusableCell를 dequeReusableSupplementaryView로 해주시면 됩니다.

 

 func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView {
        if kind == UICollectionView.elementKindSectionHeader{
            let cell = collection.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "VoiceChatCreateHeaderCollectionViewCell", for: indexPath) as! VoiceChatCreateHeaderCollectionViewCell
            cell.bind(reactor: reactor)
            return cell
        }else {
            let cell = collection.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "VoiceChatCreateFooterCollectionViewCell", for: indexPath) as! VoiceChatCreateFooterCollectionViewCell
            cell.bind(reactor: reactor)
            return cell
        }
    }
