在单元格单击时打开一个 Viewcontroller - Swift

问题描述：

我正在尝试打开一个新的视图控制器，它有一个文本字段，其中包含在 UITableView 中单击的单元格文本.虽然我已经发现了如何获取被点击单元格的信息，但我不知道如何将该值推送到新的 ViewController.这是我当前的代码:

I am trying to open a new view controller which has a textfield with the text of the cell clicked in a UITableView. Although I have already discovered how to get the clicked cell's information, I don't know how to push that value to the new ViewController. Here is my current code:

class NearbyViewController: UIViewController, UITableViewDelegate, 
    UITableViewDataSource {

    @IBOutlet weak var nearbyTableView: UITableView!
    var myList: [String] = []


    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return myList.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
        var (cellName) = myList[indexPath.row]
        cell.textLabel?.text = cellName
        return cell
    }

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
        var (cellName) = myList[indexPath.row]
        cell.textLabel?.text = cellName

        print("row\(indexPath.row)")
        print("name: \(cellName)")

    }

    override func viewDidLoad() {
        super.viewDidLoad()



}

非常感谢

一些应该对您有所帮助的 Playground 代码.使用 didSelectRowAt 中的参数调用 openDetails func.

Some playground code that should help you. Call openDetails func with parameters what you need from didSelectRowAt.

import UIKit

final class NearbyViewController: UIViewController {

    // Your controller implementation

    private func openDetails(cellName: String) {
        let detailsController = DetailedInfoViewController() // OR use storyboard.instantiate
        detailsController.cellName = cellName

        // You must have a Navigaion stack for your controller
        self.navigationController?.pushViewController(detailsController, animated: true)
    }
}

final class DetailedInfoViewController: UIViewController {
    var cellName: String!

    // Your controller implementation

    override func viewDidLoad() {
        super.viewDidLoad()

        // Set data into view outlets
    }
}
