Swift 如何通过编程识别ViewController子视图中按钮的点击动作？

在我的

mainViewController

中有一个视图

子视图

，

子视图

有4个按钮。如何识别my

mainViewController

中这些按钮的onClick操作

下面是我的主视图控制器

import UIKit

class HomeViewController: UIViewController{

 let tableList = ["HIPAA Rules", "Know Your HIPPA Status", "Covered Entity", "Business Associate"]
var metrics : [String : CGFloat] = [:]

let menuBar = MenuBar()
let table = OptionsTable()
var views : [UIView] = []
override func viewDidLoad() {

    super.viewDidLoad()

    navigationController?.navigationBar.barTintColor = UIColor.getColorFromHex(hexCode: "1B9AF7")
    navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]

    setUpTable()
}


private func setUpTable(){
    views += [table]
    view.addSubview(table)
    table.backgroundColor = UIColor.red
    //Code For Constraints Of the SubView
    table.setUpButtons(numberOfButtons: 4, buttonTitleList: tableList, optionsTableHeight: optionTableHeight)


}

class OptionsTable: UIView {


override init(frame: CGRect) {
    super.init(frame: frame)
}

func setUpButtons(numberOfButtons : Int, buttonTitleList : [String], optionsTableHeight : CGFloat) {

    let cellHeight = optionsTableHeight / CGFloat(numberOfButtons)

    for buttonNumber in 0...numberOfButtons-1{
        var views : [UIView] = []
        var metrics : [String : CGFloat] = [:]
        let paddingInTermsOfButtons = (numberOfButtons-buttonNumber)-1

        let button = UIButton()

        button.setTitle(buttonTitleList[buttonNumber], for: .normal)
        button.backgroundColor = UIColor.white
        button.layer.borderColor = UIColor.gray.cgColor
        button.layer.borderWidth = 1;
        button.setTitleColor(UIColor.black, for: .normal)


        print("For button : \(buttonNumber)" )
        print(self.frame)
        self.addSubview(button)

        views += [button]

        //Code For Constraints of the buttons

    }
}

下面是我的选项表//主ViewController的子视图

import UIKit

class HomeViewController: UIViewController{

 let tableList = ["HIPAA Rules", "Know Your HIPPA Status", "Covered Entity", "Business Associate"]
var metrics : [String : CGFloat] = [:]

let menuBar = MenuBar()
let table = OptionsTable()
var views : [UIView] = []
override func viewDidLoad() {

    super.viewDidLoad()

    navigationController?.navigationBar.barTintColor = UIColor.getColorFromHex(hexCode: "1B9AF7")
    navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]

    setUpTable()
}


private func setUpTable(){
    views += [table]
    view.addSubview(table)
    table.backgroundColor = UIColor.red
    //Code For Constraints Of the SubView
    table.setUpButtons(numberOfButtons: 4, buttonTitleList: tableList, optionsTableHeight: optionTableHeight)


}

class OptionsTable: UIView {


override init(frame: CGRect) {
    super.init(frame: frame)
}

func setUpButtons(numberOfButtons : Int, buttonTitleList : [String], optionsTableHeight : CGFloat) {

    let cellHeight = optionsTableHeight / CGFloat(numberOfButtons)

    for buttonNumber in 0...numberOfButtons-1{
        var views : [UIView] = []
        var metrics : [String : CGFloat] = [:]
        let paddingInTermsOfButtons = (numberOfButtons-buttonNumber)-1

        let button = UIButton()

        button.setTitle(buttonTitleList[buttonNumber], for: .normal)
        button.backgroundColor = UIColor.white
        button.layer.borderColor = UIColor.gray.cgColor
        button.layer.borderWidth = 1;
        button.setTitleColor(UIColor.black, for: .normal)


        print("For button : \(buttonNumber)" )
        print(self.frame)
        self.addSubview(button)

        views += [button]

        //Code For Constraints of the buttons

    }
}

因此，如何识别选项表中这些按钮的onclick操作，因为它们是动态创建的？

您必须添加目标才能识别按钮中的单击事件，如下所示

Swift

点击按钮时将调用此方法

@objc func buttonOneClicked(button: UIButton)  {
        //Do whatever you want to do here and check button tags so you will get to know which index is clicked
    }

- (void) buttonOneClicked:(UIButton *) sender {
    //Do whatever you want to do here and check button tags so you will get to know which index is clicked
}

目标-C

点击按钮时将调用此方法

@objc func buttonOneClicked(button: UIButton)  {
        //Do whatever you want to do here and check button tags so you will get to know which index is clicked
    }

- (void) buttonOneClicked:(UIButton *) sender {
    //Do whatever you want to do here and check button tags so you will get to know which index is clicked
}

为什么不共享

mainViewController

、

子视图

等的代码，以便我们更好地了解您的问题。除非您有充分的理由以编程方式执行此操作，否则使用IB和IBAction执行此操作非常简单。@RakeshaShastri请检查我的编辑设置post@claude31，是的，按钮是动态创建的。所以，如果您知道哪个按钮指向哪个viewController，那么应该维护各个变量来保存每个按钮。然后将操作添加到所有按钮。谢谢。我将尝试此操作。如果您有动态按钮，请尝试添加标记。我已经编辑了我的回答谢谢。这很有帮助。
