如何在 TableCell 类中使用 navigationController.pushViewController? [英] How to use navigationController.pushViewController in TableCell class?

问题描述

使用UITableviewcell 类来显示表格列表的单元格.我想使用navigationController?.pushViewController"从一个屏幕重定向到另一个屏幕，但它在表格单元格类中不受支持.那么如何使用表格单元格中的 pushViewController 移动 UIViewcontroller.

Using UITableviewcell class for displaying the cell of table list. I want to redirect from one screen to another using "navigationController?.pushViewController", but it is not supporting in table cell class. So how can i move UIViewcontroller using pushViewController from table cell.

我的代码是:

class TableCell: UITableViewCell
{
    let storyBoard : UIStoryboard = UIStoryboard(name: "SubMain", bundle:nil)
    let nextViewController = storyBoard.instantiateViewController(withIdentifier: "DetailReport") as! DetailReport
    nextViewController.aryOfResultList = aryForCreateJSONResult
    cell.inputViewController?.navigationController?.pushViewController(nextViewController, animated: true)

}

但它不起作用.请给我解决我的问题

But its not working. Please give me the solution of my question

推荐答案

在单元格中声明一个名为 var parent: UIViewController? 的变量.在父控制器中，在函数 cellForRow,

Declare a variable in the cell called var parent: UIViewController?. in the parent controller, in the function cellForRow,

cell.parent = self

现在可以在单元格中调用

now in the cell you can call

parent?.navigationController.pushViewController

更新如果您只想在录制单元格时推送视图控制器，您可以在父控制器中执行此操作:

Update if what u want is simply to push the view controller when a cell is taped, u can do it in the parent controller in:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
     self.navigationController?.pushViewController(nextViewController, animated: true)    
}
