TableView内部tableview单元格迅速3 [英] TableView inside tableview cell swift 3

问题描述

我正在尝试在tableview单元格中显示tableView，而父级和子级tableview都具有动态单元格高度。

I'm tring to display tableView inside tableview cell while both parent and child tableview have dynamic cell height.

第一个问题是，并非所有单元格都显示子tableview。
在显示childTableView的单元格中，childTableView的高度不正确。

First problem is not all cells show child tableView. In cells that show childTableView, childTableView height is not right.

 class ViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()
    setUpTableView();
}

func setUpTableView(){
    tableView.register(UINib(nibName: "MCQCell", bundle: nil), forCellReuseIdentifier: "MCQCell");
    tableView.estimatedRowHeight = 100;
    tableView.rowHeight = UITableViewAutomaticDimension;
}
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
 }
}   

  extension ViewController: UITableViewDelegate, UITableViewDataSource{
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if(tableView == self.tableView){
        let cell = tableView.dequeueReusableCell(withIdentifier: "MCQCell", for:indexPath) as! MCQCell
        let row = indexPath.row
        cell.lblTxt.text = items[row];
        cell.tableView.tag = row;
        cell.tableView.dataSource = self;
        cell.tableView.delegate = self;
        cell.tableView.estimatedRowHeight = 60;
        cell.tableView.rowHeight = UITableViewAutomaticDimension;
        cell.setNeedsLayout()
        return cell;
    }else{
        let cell = tableView.dequeueReusableCell(withIdentifier: "ChoiceCell", for:indexPath) as! ChoiceCell
        let row = indexPath.row
        cell.lblTxt.text = items[row];
        return cell;
    }
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if(tableView == self.tableView){
        return items.count;
    }else{
        return 5;
    }
}


func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension;
}
}

并在Parent tableview单元格内，我只注册childTableView单元格，重新加载tableview

and inside Parent tableview cell I just register childTableView cell and reloading tableview

  override func systemLayoutSizeFitting(_ targetSize: CGSize,
                             withHorizontalFittingPriority horizontalFittingPriority: UILayoutPriority,
                             verticalFittingPriority: UILayoutPriority) -> CGSize{

    tableView.reloadData()
    let size = CGSize(width: targetSize.width,
                      height: tableView.frame.origin.y + tableView.contentSize.height)
    return size

}

我在做什么错？

推荐答案

-> Disable childtableview scrolling.        

    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
                return CGFloat((ChildTableviewCellItem.count) * Height_childtableviewcell+Height_MainTableviewcell)
            }
