ios - 使用 sambag 时间选择器时出现问题

Question

我正在使用 sambag 时间选择器 Controller ，我在 sambag picker 方法的按钮上设置了时间，但问题是我在一个 View Controller 中有多个按钮，所以我在设置时为每个设置时间方法都做了这个按钮所有按钮标题都改变我想要的是只改变我按下的按钮的值

在这里，我将向您展示我的尝试，我将向您展示我的代码

   import UIKit

   class ManageHoursViewController: UIViewController {

     var theme: SambagTheme = .light

    var result : String!
    @IBOutlet weak var btnMonStartTime: UIButton!
    @IBOutlet weak var btnMonEndTime: UIButton!
    @IBOutlet weak var btnMonOff: UIButton!
    @IBOutlet weak var btnMonOn: UIButton!


    override func viewDidLoad() {
        super.viewDidLoad()
        round()

        let hh2 = (Calendar.current.component(.hour, from: Date()))
        let mm2 = (Calendar.current.component(.minute, from: Date()))
        print(hh2)
        print(mm2)
        let dateTime = "\(hh2) : \(mm2)"
        btnMonStartTime.setTitle("\(dateTime)", for: .normal)
        btnMonEndTime.setTitle("\(dateTime)", for: .normal)
        // Do any additional setup after loading the view.
    }

    func round(){

        btnMonOff.isHidden = true
        btnMonStartTime.layer.cornerRadius = btnMonStartTime.frame.height / 2
        btnMonStartTime.layer.shadowColor = UIColor(red: 154/255, green: 154/255, blue: 154/255, alpha: 1).cgColor
        btnMonStartTime.layer.shadowOffset = CGSize(width: 0, height: 1)
        btnMonStartTime.layer.shadowOpacity = 1.0
        btnMonStartTime.layer.shadowRadius = 2.0
        btnMonStartTime.layer.masksToBounds = false

        btnMonEndTime.layer.cornerRadius = btnMonEndTime.frame.height / 2
        btnMonEndTime.layer.shadowColor = UIColor(red: 154/255, green: 154/255, blue: 154/255, alpha: 1).cgColor
        btnMonEndTime.layer.shadowOffset = CGSize(width: 0, height: 1)
        btnMonEndTime.layer.shadowOpacity = 1.0
        btnMonEndTime.layer.shadowRadius = 2.0
        btnMonEndTime.layer.masksToBounds = false
    }

    @IBAction func btnMonStartTimeTapped(_ sender: UIButton) {
        let vc = SambagTimePickerViewController()
        vc.theme = theme
        vc.delegate = self
        present(vc, animated: true, completion: nil)
    }
    @IBAction func btnMonEndTimeTapped(_ sender: UIButton) {
        let vc = SambagTimePickerViewController()
        vc.theme = theme
        vc.delegate = self
        present(vc, animated: true, completion: nil)
    }
}
extension ManageHoursViewController : SambagTimePickerViewControllerDelegate {

    func sambagTimePickerDidSet(_ viewController: SambagTimePickerViewController, result: SambagTimePickerResult) {
        self.result = "\(result)"
        print(self.result)
        btnMonStartTime.setTitle(self.result, for: .normal)
        btnMonEndTime.setTitle(self.result, for: .normal)
        viewController.dismiss(animated: true, completion: nil)
    }

    func sambagTimePickerDidCancel(_ viewController: SambagTimePickerViewController) {
        viewController.dismiss(animated: true, completion: nil)
    }
}

我想当星期一开始时间按钮按下然后我选择时间表单选择器然后只有星期一开始时间按钮值更改现在所有按钮值都更改

您可以创建一个 var 来跟踪最后一次点击

 var lastBu: UIButton!


    @IBAction func btnMonStartTimeTapped(_ sender: UIButton) {
        let vc = SambagTimePickerViewController()
        vc.theme = theme
        vc.delegate = self
        lastBu = sender
        present(vc, animated: true, completion: nil) 
    }
    @IBAction func btnMonEndTimeTapped(_ sender: UIButton) {
        let vc = SambagTimePickerViewController()
        vc.theme = theme
        vc.delegate = self
        lastBu = sender
        present(vc, animated: true, completion: nil)
    }
