ios - 如何从放置在其他 TableView 单元格中的 TableView 单元格导航到 View Controller ？

Question

我已将 tableview2 放置在 tableview1 单元格中，现在当我单击 tableview2 单元格时，我需要导航到新的 viewController。请帮助我...我一整天都在挣扎:(

这是代码，第二个 TableView 放置在SegmentedCell中...当我尝试插入时，它无法进入下一个 Controller ..

//如何从这里执行

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    if segmentedControl.selectedSegment == 1
    {
        let storyboard = UIStoryboard(name: "Main", bundle : nil)
        let nextViewController = storyboard.instantiateViewController(withIdentifier: "QuickLook") as! QuickLook


        if materialListObjects[indexPath.row].type == "url"
        {
            nextViewController.id = materialListObjects[indexPath.row].body
            nextViewController.type = "url"
        }
        else
        {
            nextViewController.id = materialListObjects[indexPath.row].id
        }
        nextViewController.course_id = String(describing: materialListObjects[indexPath.row].course_id)
        let naviControl = UINavigationController(rootViewController: nextViewController)
        naviControl.pushViewController(nextViewController, animated: true)



    }

}

}

Answer 1

我创建了一个与您类似的场景，这就是让它发挥作用的方法。

<强>1。 查看层次结构

我使用 tag 属性来唯一标识两个 UITableViews，即

1. 外部 tableView 标签 = 0
2. 内部 tableView 标记 = 1

2. 现在为两个 tableView 实现 UITableViewDataSource、UITableViewDelegate 方法。将两个 tableView 的 dataSource 和 delegate 设置为 ViewController。

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
    if tableView.tag == 0
    {
        return 1
    }
    else if tableView.tag == 1
    {
        return 5
    }
    return 0
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
    if tableView.tag == 0
    {
        return tableView.dequeueReusableCell(withIdentifier: "outercell", for: indexPath)
    }
    else if tableView.tag == 1
    {
        return tableView.dequeueReusableCell(withIdentifier: "innercell", for: indexPath)
    }
    return UITableViewCell()
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
    if tableView.tag == 1
    {
        //TODO: Write your code for navigating to another ViewController here
        print("Inner cell tapped")
    }
}

编辑:

在Interface Builder中，您可以在attributes Inspector中找到与每个元素对应的tag属性，即

对于outer tableView，将其设置为0，对于inner tableView，将其设置为1。

如果您仍然遇到任何问题，请告诉我。快乐编码..🙂
