UIImageView 未调整为圆形，UILabel 未在 StackView 和自定义集合单元中调整大小

Question

但是，我正在尝试将我的 UIImageView 调整为一个圆圈；每次我尝试调整与UILabel 一起位于 StackView 内的UIImageView 的大小时，我都会继续以更矩形的形状结束。有人可以告诉我我哪里出错了我已经坚持了好几天了吗？下面是我的代码，它试图做的是在底部添加带有标签的图像，并且图像应该是圆形的，这应该是我的集合视图控制器。

自定义集合视图单元格

import UIKit

class CarerCollectionViewCell: UICollectionViewCell {
    static let identifier = "CarerCollectionViewCell"
    
    private let imageView: UIImageView = {
        let imageView = UIImageView()
        imageView.frame = CGRect(x: 0, y: 0, width: 20, height: 20);
        //imageView.center = imageView.superview!.center;
        imageView.contentMode = .scaleAspectFill
        imageView.layer.borderWidth = 4
        imageView.layer.masksToBounds = false
        imageView.layer.borderColor = UIColor.orange.cgColor
        imageView.layer.cornerRadius = imageView.frame.height / 2
        return imageView
    }()
    
    private let carerNamelabel: UILabel = {
        let carerNamelabel = UILabel()
        carerNamelabel.layer.masksToBounds = false
        carerNamelabel.font = .systemFont(ofSize: 12)
        carerNamelabel.textAlignment = .center
        carerNamelabel.layer.frame = CGRect(x: 0, y: 0, width: 50, height: 50);
        return carerNamelabel
    }()
    
    private let stackView: UIStackView = {
        let stackView = UIStackView()
        stackView.layer.masksToBounds = false
        stackView.axis = .vertical
        stackView.alignment = .center
        stackView.backgroundColor = .systemOrange
        stackView.distribution = .fillProportionally
        stackView.translatesAutoresizingMaskIntoConstraints = false
        return stackView
    }()
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        configureContentView()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
    }
    
    private func configureContentView() {
        imageView.clipsToBounds = true
        stackView.clipsToBounds = true
        carerNamelabel.clipsToBounds = true
        contentView.addSubview(stackView)
        configureStackView()
    }
    
    private func configureStackView() {
        allContraints()
        stackView.addArrangedSubview(imageView)
        stackView.addArrangedSubview(carerNamelabel)
    }
    
    private func allContraints() {
        setStackViewConstraint()
    }
    
    private func setStackViewConstraint() {
        stackView.widthAnchor.constraint(equalTo: contentView.widthAnchor).isActive = true
        stackView.heightAnchor.constraint(equalTo: contentView.heightAnchor).isActive = true
        stackView.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
        stackView.centerYAnchor.constraint(equalTo: contentView.centerYAnchor).isActive = true
    }
    
    
    
    public func configureImage(with imageName: String, andImageName labelName: String) {
        imageView.image = UIImage(named: imageName)
        carerNamelabel.text = labelName
    }
    
    override func layoutSubviews() {
        super.layoutSubviews()
        stackView.frame = contentView.bounds
    }
    
    override func prepareForReuse() {
        super.prepareForReuse()
        imageView.image = nil
        carerNamelabel.text = nil
    }
}

下面是我的 CollectionViewControler 代码

自定义集合视图

import UIKit

class CarerViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
    
    private var collectionView: UICollectionView = {
        let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .vertical
        layout.itemSize = CGSize(width: 120, height: 120)
        let collectionView = UICollectionView(frame: .zero, collectionViewLayout: layout)
        collectionView.register(CarerCollectionViewCell.self, forCellWithReuseIdentifier: CarerCollectionViewCell.identifier)
        collectionView.showsVerticalScrollIndicator = false
        collectionView.backgroundColor = .clear
        return collectionView
    }()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        collectionView.delegate = self
        collectionView.dataSource = self
        view.addSubview(collectionView)
        collectionView.translatesAutoresizingMaskIntoConstraints = false
        // Layout constraints for `collectionView`
        NSLayoutConstraint.activate([
            collectionView.widthAnchor.constraint(equalTo: view.widthAnchor),
            collectionView.heightAnchor.constraint(lessThanOrEqualTo: view.heightAnchor, constant: 600),
            collectionView.topAnchor.constraint(equalTo: view.topAnchor, constant: 200),
            collectionView.leadingAnchor.constraint(equalTo: view.leadingAnchor)
        ])
    }
    
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 10
    }
    
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: CarerCollectionViewCell.identifier, for: indexPath) as! CarerCollectionViewCell
        cell.configureImage(with: "m7opt04g_ms-dhoni-afp_625x300_06_July_20", andImageName: "IMAGE NO. 1")
        return cell
    }
}

谁能告诉我或指出我做错了什么，谢谢 This is what I am trying to achieve

UIStackView 有时可能会很棘手，您可以将UIImageView 嵌入到UIView 中，并将布局代码移动到viewWillLayoutSubviews()，这也意味着UILabel 也嵌入在UIView 中，因此容器 UIViews 将有一个静态框架，以便 UIStackView 正确布局，其中的内容只会影响自身。
