如何在点击手势上显示uidatePicker日历？

Question

我有一个嵌入在uiimageView中的uidatePicker视图。我想创建一个功能，当uiimageView被点击时，uidatePicker的日历出现在屏幕上。我还希望uidatePicker具有与UIImageView匹配的自定义背景颜色。

我尝试的是：

1. 将uitapgestureRerecognizer添加到UIImageView，使UIDEDPICKER成为第一响应者
2. ，将UIDESPICKER的背景颜色设置为自定义的RGB颜色（也可以清楚地尝试），

是否有一种使UIDESPICKER在UidatePicker的日程表中出现的方法单击UIimageView并将自定义颜色添加到UIDESPICKER？

class VieController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .white
        view.addSubview(section)
        section.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            section.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor),
            section.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            section.widthAnchor.constraint(equalTo: view.widthAnchor,
                                                   multiplier: 0.8)
        ])
    }
    
    lazy var datePicker: UIDatePicker = {
        let picker = UIDatePicker()
        picker.datePickerMode = .date
        picker.translatesAutoresizingMaskIntoConstraints = false
        picker.backgroundColor = UIColor(red: 246.0, green: 240.0, blue: 220.0, alpha: 1.0)
        return picker
    }()
    
    lazy var section: UIImageView = {
        let iv = UIImageView(image: Image.setButtonBg)
        iv.isUserInteractionEnabled = true
        iv.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(didTapCalendar)))

        let calendarIV = UIImageView()
        calendarIV.image = UIImage(systemName: "calendar")
        calendarIV.translatesAutoresizingMaskIntoConstraints = false
        
        iv.addSubview(datePicker)
        iv.addSubview(calendarIV)
        
        NSLayoutConstraint.activate([
            datePicker.centerXAnchor.constraint(equalTo: iv.centerXAnchor),
            datePicker.centerYAnchor.constraint(equalTo: iv.centerYAnchor),
            calendarIV.centerYAnchor.constraint(equalTo: iv.centerYAnchor),
            calendarIV.leadingAnchor.constraint(equalTo: iv.leadingAnchor,
                                                constant: 15)
        ])

        return iv
    }()
    
    @objc func didTapCalendar() {
        datePicker.becomeFirstResponder()
    }
}
