如何在有物料的交换机上执行操作(CosmicMind)

Question

我正在尝试在我的应用程序中添加一个开关。我在故事板中添加了它(带有Switch类和Material模块的IUView。我在我的视图控制器中自定义了它，但是我不知道如何在它上面做动作。

我尝试添加带有touch事件的IBAction，但是当我触摸它的时候什么都没有。

谢谢。

我的代码：

import Foundation
import UIKit 
import Material

class SettingsVC: UIViewController {

    @IBOutlet weak var addCalendarSwitch: Switch!

    override func viewDidLoad() {
        super.viewDidLoad()

        addCalendarSwitch.delegate = self
        addObserver()
        setStyle()
        setView()
        getStatusAddCalendar()
    }

    func getStatusAddCalendar(){
        if UserDefaults.standard.bool(forKey: "addToCalendar") == true 
        {
            addCalendarSwitch.isOn = true
        }
        else {
            addCalendarSwitch.isOn = false
        }
    }
}

extension ViewController: SwitchDelegate {

    // utilise the delegate method
    func switchDidChangeState(control: Switch, state: SwitchState) {
        print("Switch changed state to: ", .on == state ? "on" : "off")
    }
}

从示例中看，它似乎使用了委托模式。https://github.com/CosmicMind/Samples/blob/master/Projects/Programmatic/Switch/Switch/ViewController.swift

import UIKit
import Material

class ViewController: UIViewController {

    // create an outlet and connect it from your storyboard
    @IBOutlet weak var mySwitch: Switch!

    override func viewDidLoad() {
        super.viewDidLoad()
        // use this outlet to assign the delegate
        mySwitch.delegate = self
    }
}

// conform to the protocol
extension ViewController: SwitchDelegate {

    // utilise the delegate method
    func switchDidChangeState(control: Switch, state: SwitchState) {
        print("Switch changed state to: ", .on == state ? "on" : "off")
    }
}
