通过快速单击TableView单元格转到ViewController [英] Go to the ViewController by clicking on the TableView cell in swift

问题描述

有一个MenuViewController类，其中记录了表中记录的数组:

there is a class MenuViewController in which the array recorded in the table is recorded:

import Foundation
import UIKit

class MenuViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

@IBOutlet weak var menuTableView: UITableView!

let myTitle = ["Помощь", "Информация", "Поддержка"]


override func viewDidLoad() {
    super.viewDidLoad()


    menuTableView.delegate = self
    menuTableView.dataSource = self
}

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

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = menuTableView.dequeueReusableCell(withIdentifier: "MenuCell") as! MenuTableViewCell
    cell.labelText.text = myTitle[indexPath.row]
    return cell
}
}

您需要在其中写什么才能进入信息控制器?

What do you need to write in it to go to Info Controller?

推荐答案

我假设您正在使用情节提要.首先，您需要在两个视图控制器之间建立某种连接.您可以通过设置"segue"来做到这一点.您按住ctrl键并单击从第一个视图控制器到第二个视图控制器的拖动.看起来像这样:

I assume you are using storyboards. First you need to set up some sort of connection between your two viewcontrollers. You can do this by setting up a "segue". You hold ctrl+click drag from the first viewcontroller to the 2nd viewcontroller. It looks like this:

放开鼠标，您将看到以下内容:

When you let go of the mouse, you will see this:

单击显示".现在，您将创建一个segue. 现在您需要命名.因此，请单击情节提要中显示的segue.它基本上只是从菜单视图控制器到信息视图控制器的箭头.在右侧，您会看到一个可以命名的地方(给它一个标识符):

Click on Show. Now you will have created a segue. Now you need to name it. So click on the segue that shows up in the storyboard. It is basically just an arrow from the Menu View Controller to the Info View Controller. On the right hand side you will see a place where you can name it (give it an identifier):

现在...您已经完成了情节提要中需要做的所有事情.现在，在MenuViewController中的实际代码中，需要关联单击tableviewcell.您可以通过使用委托方法didSelectRowAt来做到这一点.

Now ... you have done all you needed to do in the storyboard. Now in your actual code in the MenuViewController, you need to associate clicking the tableviewcell. You do this by using the delegate method didSelectRowAt.

我看到您已经用以下行设置了委托: menuTableView.delegate = self

I see you have already set up the delegate with this line: menuTableView.delegate = self

这确保了didSelectRowAt会在用户点击行时被调用.

That ensures that didSelectRowAt will be called whenever the user taps on a row.

所以现在您要做的是编写代码来执行segue:

So now what you want to do is write the code to perform the segue:

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