Ios 从嵌套数据数组向UITableViewCell内的UITableView填充数据,ios,swift,uitableview,Ios,Swift,Uitableview,我是swift和iOS编程新手。我正在尝试制作一个两层的桌面视图。Tableview单元格中的Tableview基本上就是我想说的。主tableview工作正常，但tableview中的tableview根本不工作。。我什么都试过了 #型号 // Main Model Struct struct MainModel { private(set) public var title: String private(set) public var document: [Documents] =

这个方法永远不会被调用。。。为什么？我想这可能就是问题所在

// from: MainTableViewCell
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
                if let cell = tableView.dequeueReusableCell(withIdentifier: “documentTableCell”) as? DocumentCell {
                    let _doc = documentRes[indexPath.row]
                    cell.updateDocument(document: _doc)
                    return cell
                } else {
                  return DocumentCell()
                }
            }

请帮帮我

在

MainTableViewCell

do的

updateCell

末尾

self.documentTable.reloadData()

不，先生，那不行。该代码没有对以前的状态进行任何更改..您确定如果调用了let inside cellForRowAt吗？调用了返回Main TableViewCell的cellForRowAt，并且工作正常，但是应该返回documentCell的cellForRowAt，inside Main TableViewCell没有响应。是否使用xib或prototype cell？不仅仅是如果让，但是返回documentCell的整个方法不起作用。。。
