如何为静态 TableView 单元格点击添加动作？

Question

how can i respond to cell taps in static tableview? Is there a way to link it with code? I know that i can use a dynamic one but isn't it possible with a static one?

didSelectRowAt doesn't get called

Code for Selecting not working

class SettingsVC: UITableViewController, UITabBarControllerDelegate {

    // MARK: - View lifecycle
    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.delegate = self
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("SELECTED") // not get called
    }
}

Answer 1

You need to either:

1. Change SettingsVC to be a subclass of UITableViewController .
2. Make SettingsVC the delegate of your table view, since tableView(_:didSelectRowAt:) is a method of UITableViewDelegate .

Answer 2

This can be done using a Static table in a UIContainerView .

Here is the Storyboard setup:

and how it looks at run-time:

When you use a UIContainerView it creates an embed segue... and that will trigger a prepare call where you can set the tableView's delegate to self (if desired).

Here's the code:

import UIKit

class EmbedTestViewController: UIViewController, UITableViewDelegate {

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        // When using UIContainerView, prepare for segue will be called on load

        // un-comment this block to use SELF as the delegate
        //  for the tableView in the embedded tableViewController

        //if let vc = segue.destination as? MyStaticTableViewController {
        //  vc.tableView.delegate = self
        //}

    }

    // this will only be called if .delegate is set as shown above
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("didSelectRowAt called in \"Parent\" for indexPath:", indexPath)
    }

}

class MyStaticTableViewController: UITableViewController {

    // this will NOT be called if .delegate is set as the "parent" view controller
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("didSelectRowAt called in \"Table View Controller\" for indexPath:", indexPath)
    }

}

Note the comments and commented lines of code in the prepare func in EmbedTestViewController .

If you run this with those lines commented, didSelectRowAt will be called in MyStaticTableViewController class.

If you un-comment those lines, didSelectRowAt will be called in EmbedTestViewController class.
