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 ..

最佳答案
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
- 外部 tableView 标签 = 0
- 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..🙂
