ios - 如果单元格被触摸 - 移动到另一个 VC [SWIFT]

Question

如果单元格被触摸 - 移动到另一个 VC，我该怎么办？ 我尝试去做，但没有成功。 这是我的代码

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "transData" {
        let destination = segue.destination as! WinnerViewController

        let cell = sender as? UITableViewCell

        if cell == cell {
            let indexPath = tableView.indexPath(for: cell!)
            if indexPath == indexPath {
                let productName = users[(indexPath?.row)!]
                destination.winner = productName.name
            }
        }
    }

当我触摸每个细胞时 - 它没有移动。 请帮忙

点击单元格时有两种执行转场的选项。

1. segue 从 TableView 单元格连接到目标 Controller

   在本例中，单元格作为 sender 参数传递

   override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
       if segue.identifier == "transData", let cell = sender as? UITableViewCell {
            let destination = segue.destination as! WinnerViewController
            let indexPath = tableView.indexPath(for: cell)!  
            let productName = users[indexPath.row]
            destination.winner = productName.name
       }
   }
   

2. segue 从源 Controller 连接到目标 Controller

   在这种情况下，您必须实现didSelectRowAt，调用performSegue(withIdentifier)并将索引路径作为sender参数传递

   func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
       performSegue(withIdentifier: "transData", sender: indexPath)
    }
   

   然后准备(因为必须是

   override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
       if segue.identifier == "transData", let indexPath = sender as? IndexPath {
            let destination = segue.destination as! WinnerViewController
            let productName = users[indexPath.row]
            destination.winner = productName.name
       }
   }
