컬렉션보기에 대해 여러 데이터 소스를 만드는 방법은 무엇입니까?

Question

두 개의 셀이있는 tableview와이 셀 안에있는 두 개의 embeddedviewview가 있습니다. 내 앱이 두 번째 셀을 큐에 넣으려고 할 때 내 앱이 계속 충돌합니다. Ash Furrows 튜토리얼을이 프로젝트의 기초로 삼아 여기에서 링크 할 것입니다. Tutorial link

이 문제를 어떻게 해결할 수 있습니까? 다음은 몇 가지 샘플 코드입니다.

내가 그들 각각이 코드

class TableViewCell: UITableViewCell { 

    @IBOutlet weak var collectionView: UICollectionView! 

    override func awakeFromNib() { 
     super.awakeFromNib() 
     // Initialization code 
    } 

    override func setSelected(_ selected: Bool, animated: Bool) { 
     super.setSelected(selected, animated: animated) 

     // Configure the view for the selected state 
    } 

    func setCollectionViewDataSourceDelegate <D: UICollectionViewDataSource & UICollectionViewDelegate> (dataSourceDelegate: D, forRow row: Int) { 
     collectionView.delegate = dataSourceDelegate 
     collectionView.dataSource = dataSourceDelegate 
     collectionView.tag = row 
     collectionView.reloadData() 
    } 
} 

이와 함께 자신의 클래스를 가진 두 개의 서로 다른 세포가 코드의 나머지 부분은 내가 내 휴대

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) { 
     if indexPath.section == 1 { 
      guard let tableViewCell = cell as? TableViewCell else { 
       return 
      } 

      tableViewCell.setCollectionViewDataSourceDelegate(dataSourceDelegate: self, forRow: indexPath.row) 
     } 

     if indexPath.section == 2 { 
      guard let tableViewCell2 = cell as? TableViewCell2 else { 
       return 
      } 
      tableViewCell2.setCollectionViewDataSourceDelegate(dataSourceDelegate: self, forRow: indexPath.row) 
     } 


     // we store the offset from here into the dictionary we created above 
     //tableViewCell.collectionViewOffset = storedOffsets[indexPath.row] ?? 0 
    } 

    func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath) { 
     guard let tableViewCell = cell as? TableViewCell else { return } 

     storedOffsets[indexPath.row] = tableViewCell.collectionViewOffset 
    } 

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { 
     print(indexPath) 
    } 
} 

// collectionView inside tableview cell 

extension TabViewController1: UICollectionViewDelegate, UICollectionViewDataSource { 

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
     return model[collectionView.tag].count 
    } 

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 


     if let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath) as? CollectionCell1 { 
      cell.backgroundColor = UIColor.gray 
      return cell 
     } 

     if let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell2", for: indexPath) as? CollectionCell2 { 
      cell.backgroundColor = UIColor.purple 
      return cell 
     } 

     return UICollectionViewCell() 
    } 

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { 
     print("Collection view at row \(collectionView.tag) selected index path \(indexPath)") 
    } 
}

Answer 1

, 그것은 확실히 말하기 어렵지만, 내 의심은 다른 뭔가 돌아가고 있다는 것입니다 -cellForRow ... 또는 -cellForItemAt ... 메소드에서 TableViewCell2 (또는 실제로 충돌하는 곳)보다 더 큽니다. 귀하의 모든 힘을 푸는 (!) 문제가 발생할 가능성이 높습니다. 크래시 바로 전에 중단 점을 넣고 -dequeueReusableCell 호출에서 실제로 돌아 오는 것을 확인하십시오.
