Angular-设计对象以与表单交互的参考

Question

我是设计新系统的团队的一部分。我们选择Angular作为我们的前端框架，并开始研究它的实现。

现在我遇到了障碍。我的想法是在html上创建输入，并基于Angular中的对象填充，隐藏或标记它们，我想为每个输入创建单个对象，例如：

import UIKit
import Foundation

extension UIView {
    func currentFirstResponder() -> UIResponder? {
        if self.isFirstResponder {
            return self
        }

        for view in self.subviews {
            if let responder = view.currentFirstResponder() {
                return responder
            }
        }

        return nil
    }
}

extension Notification.Name{
    static let showKeyboard = Notification.Name("showKeyboard")
}

class KeyboardSlider: NSObject {
    // variables to hold and process information from the view using this class
    weak var view: UIView?
    var searchBarTopTags:SearchBarTopTagsViewController?
    var amountToShiftBy:CGFloat!
    var originalFrame:CGRect!

    @objc func keyboardWillShow(notification: NSNotification) {
        self.originalFrame = self.searchBarTopTags?.myView.frame
        self.amountToShiftBy = (self.searchBarTopTags?.view.frame.maxY)! - self.getKeyboardHeight(notification as! Notification) - (self.searchBarTopTags?.myView.frame.height)!
        self.amountToShiftBy = (searchBarTopTags?.view.bounds.height)! - self.getKeyboardHeight(notification as! Notification) - (searchBarTopTags?.myView.bounds.height)!
        self.searchBarTopTags?.myView.bottomAnchor.constraint(equalTo: (self.searchBarTopTags?.view.bottomAnchor)!, constant: -self.amountToShiftBy).isActive = true

        UIView.animate(withDuration: 0, animations: {
            self.view?.layoutIfNeeded()
            self.searchBarTopTags?.view.layoutIfNeeded()
            self.searchBarTopTags?.myView.layoutIfNeeded()        })

    }

    @objc func keyboardWillHide(notification:NSNotification){

        self.searchBarTopTags?.myView.bottomAnchor.constraint(equalTo: (self.searchBarTopTags?.view.bottomAnchor)!, constant: 0).isActive = true
        UIView.animate(withDuration: 0, animations: {
            self.view?.layoutIfNeeded()
            self.searchBarTopTags?.view.layoutIfNeeded()
            self.searchBarTopTags?.myView.layoutIfNeeded()
        })
    }
    func getKeyboardHeight(_ notification:Notification) -> CGFloat {
        // get exact height of keyboard on all devices and convert to float value to return for use
        let userInfo = notification.userInfo
        let keyboardSize = userInfo![UIKeyboardFrameEndUserInfoKey] as! NSValue
        return keyboardSize.cgRectValue.height
    }

    func subscribeToKeyboardNotifications(view: UIView) {
        // assigning view to class' counterpart
        self.view = view
        // when UIKeyboardWillShow do keyboardWillShow function
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)), name: .UIKeyboardWillShow, object: nil)
    }


    func subscribeToKeyboardNotifications(view: UIView, seachBarTopTagsVC:SearchBarTopTagsViewController? = nil) {
        // assigning view to class' counterpart
        self.view = view
        self.searchBarTopTags = seachBarTopTagsVC

        // when UIKeyboardWillShow do keyboardWillShow function
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)), name: .UIKeyboardWillShow, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: .UIKeyboardWillHide, object: nil)
    }


    func unsubscribeFromKeyboardNotifications() {
        NotificationCenter.default.removeObserver(self, name: .UIKeyboardWillShow, object: nil)
        NotificationCenter.default.removeObserver(self, name: .UIKeyboardWillHide, object: nil)
    }

}

另一个想法是，从以下开始为该对象的每个部分创建对象：

inputPhone = {
    'label': 'Mobile phone',
    'placeholder': '987 333 987',
    'validate': {
        'required': true
    },
    'options': {
        'required': true,
        'hidden': false
    }
};

因此，我想让它更多地了解是否有某种东西与我在某处错过的标准接近。
