将子视图添加到堆栈视图以设置背景颜色的函数或类

Question

我正在创建一个输入表单，每个输入行（标签和文本字段）都是使用堆栈视图排列的。我试图为特定的堆栈视图添加白色背景颜色。我已经实现了它，但是努力创建它作为一个函数或类来更容易地控制哪些堆栈视图来获得背景。

有关将此转换为可在整个项目中使用的函数或类的任何提示吗？ （注意：当前的解决方案，只为最后一个堆栈视图添加背景颜色而不是所有..还没有修复那个..）

 import UIKit
 import Firebase

class createActivityVC: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

    // runs the functions to add backgrounds to the stackviews

    pinBackground(backgroundView, to: nameStackView)
    pinBackground(backgroundView, to: typeStackView)
    pinBackground(backgroundView, to: weaponStackView)
    pinBackground(backgroundView, to: killStackView)
    pinBackground(backgroundView, to: sightingsStackView)
    pinBackground(backgroundView, to: noteStackView)

    // Do any additional setup after loading the view.
}

// Outlets used to set bacground color
@IBOutlet weak var nameStackView: UIStackView!
@IBOutlet weak var typeStackView: UIStackView!
@IBOutlet weak var weaponStackView: UIStackView!
@IBOutlet weak var killStackView: UIStackView!
@IBOutlet weak var sightingsStackView: UIStackView!
@IBOutlet weak var noteStackView: UIStackView!

// Normal outlets
@IBOutlet weak var name: UITextField! // required
@IBOutlet weak var type: UITextField! // required - type of hunt
@IBOutlet weak var weapon: UITextField! // required - weapon name
@IBOutlet weak var kills: UITextField! // optional (eg. 1)
@IBOutlet weak var sightings: UITextField! // optional (eg. 2)
@IBOutlet weak var note: UITextField! // optional short description of the hunt

@IBOutlet weak var saveBtn: UIButton!
@IBOutlet weak var cancelBtn: UIButton!



@IBAction func saveBtnWasPressed(_ sender: Any) {
    if name.text != nil && type.text != nil && weapon.text != nil {
        saveBtn.isEnabled = false // disabled the btn while uploading data - this ensure that user can't send the form twice

        DataService.instance.uploadPost(uid: (Auth.auth().currentUser?.uid)!, name: name.text!, type: type.text!, weapon: weapon.text!, kills: kills.text!, sightings: sightings.text!, note: note.text!,  withGroupKey: nil, sendComplete: {
            (isComplete) in
        if isComplete {
            self.saveBtn.isEnabled = true
            self.dismiss(animated: true, completion: nil)

        } else {
            self.saveBtn.isEnabled = true
            print("There was an error with uploading the activity")
        }

        })


    }

}
@IBAction func cancelBtnWasPressed(_ sender: Any) {
    self.dismiss(animated: true, completion: nil)
}


private lazy var backgroundView: UIView = {
    let view = UIView()
    view.backgroundColor = .white
    return view
}()

private func pinBackground(_ view: UIView, to stackView: UIStackView) {
    view.translatesAutoresizingMaskIntoConstraints = false
    stackView.insertSubview(view, at: 0)
    view.pin(to: stackView)
}

}

public extension UIView {
public func pin(to view: UIView) {
    NSLayoutConstraint.activate([
        leadingAnchor.constraint(equalTo: view.leadingAnchor),
        trailingAnchor.constraint(equalTo: view.trailingAnchor),
        topAnchor.constraint(equalTo: view.topAnchor),
        bottomAnchor.constraint(equalTo: view.bottomAnchor)
        ])
}
}

这就是它现在的样子..

这是代码。您可以为任何堆栈视图添加背景颜色。 您可以像stack

一样为stackview添加颜色

{{1}}
