swift - stackView で画像のサイズを変更し、アスペクト比を維持します

Question

Apple Maps アプリの UIButton を複製したいのですが、次のようになります。

これは私のコードです:

 class CustomView: UIImageView {
    init(frame: CGRect, corners: CACornerMask, systemName: String) {
        super.init(frame: frame)
        self.createBorders(corners: corners)
        self.createImage(systemName: systemName)
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    func createBorders(corners: CACornerMask) {
        self.contentMode = .scaleAspectFill
        self.clipsToBounds = false
        self.layer.cornerRadius = 10
        self.layer.maskedCorners = corners
        self.layer.masksToBounds = false
        self.layer.shadowOffset = .zero
        self.layer.shadowColor = UIColor.gray.cgColor
        self.layer.shadowRadius = 10
        self.layer.shadowOpacity = 0.2
        self.backgroundColor = .white
        let shadowAmount: CGFloat = 2
        let rect = CGRect(x: 0, y: 2, width: self.bounds.width + shadowAmount * 0.1, height: self.bounds.height + shadowAmount * 0.1)
        self.layer.shadowPath = UIBezierPath(rect: rect).cgPath

    }
    
    func createImage(systemName: String) {
        let image = UIImage(systemName: systemName)!
//        let renderer = UIGraphicsImageRenderer(bounds: self.frame)
//        let renderedImage = renderer.image { (_) in
//            image.draw(in: frame.insetBy(dx: 16, dy: 30))
//        }
//      self.image = renderedImage.withRenderingMode(.alwaysTemplate)
        self.image = image
    }
}

そして、次のように使用しました：

 let size = CGSize(width: 10, height: 10)
    let frame = CGRect(origin: CGPoint(x: 360, y: 45), size: size)
    let infoView = CustomView(frame: frame, corners: [.layerMinXMinYCorner, .layerMaxXMinYCorner], systemName: "info.circle")
    let locationView = CustomView(frame: frame, corners: [], systemName: "location")
    let plusView = CustomView(frame: frame, corners: [.layerMinXMaxYCorner, .layerMaxXMaxYCorner], systemName: "plus.circle")
    let binocularsView = CustomView(frame: frame, corners: [.layerMinXMinYCorner, .layerMinXMaxYCorner, .layerMaxXMinYCorner, .layerMaxXMaxYCorner], systemName: "binoculars.fill")
    let stackView = UIStackView(arrangedSubviews: [infoView, locationView, plusView, binocularsView])
    stackView.frame = CGRect(origin: CGPoint(x: 360, y: 45), size: CGSize(width: 45, height: 180))
    stackView.distribution = .fillEqually
    stackView.axis = .vertical
    stackView.setCustomSpacing(3, after: plusView)
    view.addSubview(stackView)

このコードでは、次のようになります。

ご覧のとおり、アイコンが大きすぎます...これは私がそれらを縮小しようとしたものです:(createImage()の行のコメントを外しました)

func createImage(systemName: String) {
    let image = UIImage(systemName: systemName)!
    let renderer = UIGraphicsImageRenderer(bounds: self.frame)
    let renderedImage = renderer.image { (_) in
        image.draw(in: frame.insetBy(dx: 16, dy: 30))
    }
  self.image = renderedImage.withRenderingMode(.alwaysTemplate)
}

しかし、それは歪んでいます...

私を助けることができますか？:)

ありがとうございました！！！！
