Ios 按钮iAction在子视图上不起作用

我不熟悉

Swift

和

IOS

编程。我所做的就是在ViewController SelectionViewVC中调用yearSelectionVC子视图

我在SelectionViewVC中所做的就是使用UISegmentedControl将子视图更改为不同的ViewController。但是，我试图通过interface builder在子视图上添加一些按钮，并在按下按钮时使用

iAction

触发一些代码，但这些按钮根本不起作用。我已检查子视图中的所有按钮是否链接到相同的

iAction

代码，如何使这些按钮正常工作？谢谢你的帮助

注意：子视图是在XIB文件中创建的

class SelectionViewVC: UIViewController {
    var requestd_date:Date = Date()
    @IBOutlet weak var requested_date_label: UILabel!
    @IBOutlet weak var viewContainer: UIView!
    var views:[UIView]!
    static var selected_year = 0
    static var selected_month = 0
    static var selected_day = 0
    static var selected_hour = 0
    static var selected_minute = 0

    override func viewDidLoad() {
        super.viewDidLoad();
        updateCurrentDate()
        SelectionViewVC.selected_year = current_year
        SelectionViewVC.selected_month = current_month
        SelectionViewVC.selected_day = current_day
        SelectionViewVC.selected_hour = current_hour
        SelectionViewVC.selected_minute = current_minute
        views = [UIView]()
        views.append(yearSelectionVC().view)
        views.append(monthSelectionVC().view)
        views.append(dateSelectionVC().view)
        views.append(hourSelectionVC().view)
        views.append(minuteSelectionVC().view)
        for view in views {
            viewContainer.addSubview(view)
        }
        viewContainer.bringSubview(toFront: views[0])
        let rightBarButton = UIBarButtonItem(title: "Submit", style: UIBarButtonItemStyle.plain, target: self, action: #selector(SelectionViewVC.submitButtonTapped(_:)))

        self.navigationItem.rightBarButtonItem = rightBarButton
        let request_date_string = dateFormatter.string(from: requestd_date)
        requested_date_label.text = "Date Requested to input: \(request_date_string)"
    }

您是否已验证该函数未在操作中使用断点或简单的打印语句进行调用？关于代码的可能改进的两件事：1）在Swift中，将类名大写（

yearSelectionVC

–>

yearSelectionVC

）被视为标准。2） 查看您可以连接所有按钮的outlet集合，这样您就不必编写

yearButtonList.append（…）

大约1000次；）您有一个iAction，但它跟踪的是什么操作？您可能正在跟踪非触摸的内容，例如

valueChanged

@BrunoRocha am跟踪内部的触摸Event@LinusGeffarth谢谢你的建议：D
