图像编辑应用程序。它可以缩放图像与pinchGesture，旋转它与rotateGesture和拖动从角落来调整图像大小。图像附近有2个按钮。一个旋转按钮-这一个触发图像的旋转，和一个删除图像按钮。
现在，当我收缩或旋转按钮时，按钮不再位于图像的右侧。约束正在被破坏。以下是破坏约束后的外观：

这是如果一切都好

private let imageView: UIImageView = {
        let imageView = UIImageView()
        let bundlePath = Bundle.main.path(forResource: "lockscreen", ofType: "jpeg")
        imageView.translatesAutoresizingMaskIntoConstraints = false
        imageView.image = UIImage(contentsOfFile: bundlePath ?? "")
        imageView.isUserInteractionEnabled = true
        imageView.contentMode = .scaleToFill
        imageView.clipsToBounds = false
        return imageView
    }()

    private let rotateButton: UIButton = {
        let button = UIButton()
        button.translatesAutoresizingMaskIntoConstraints = false
        let newSize = CGSize(width: 25, height: 25)
        let image = UIImage(systemName: "rotate.left")
        let resizedImage = image?.withConfiguration(UIImage.SymbolConfiguration(pointSize: newSize.width, weight: .medium))
        button.setImage(resizedImage, for: .normal)
        button.tintColor = .systemPink
        button.isHidden = true
        return button
    }()

    private let deleteButton: UIButton = {
        let button = UIButton()
        button.translatesAutoresizingMaskIntoConstraints = false
        let newSize = CGSize(width: 25, height: 25)
        let image = UIImage(systemName: "trash")
        let resizedImage = image?.withConfiguration(UIImage.SymbolConfiguration(pointSize: newSize.width, weight: .medium))
        button.setImage(resizedImage, for: .normal)
        button.tintColor = .systemPink
        button.isHidden = true
        return button
    }()

    private var topLeftCircleView = CircleView()
    private var topRightCircleView = CircleView()
    private var bottomLeftCircleView = CircleView()
    private var bottomRightCircleView = CircleView()

    private var borderView = UIView()

    private var imageViewTopConstraint: NSLayoutConstraint!
    private var imageViewBottomConstraint: NSLayoutConstraint!
    private var imageViewLeftConstraint: NSLayoutConstraint!
    private var imageViewRightConstraint: NSLayoutConstraint!

    private var rotateButtonBottomAnchorConstraint: NSLayoutConstraint!
    private var rotateButtonTrailingAnchorConstraint: NSLayoutConstraint!
    private var deleteButtonTopAnchorConstraint: NSLayoutConstraint!
    private var deleteButtonTrailingAnchorConstraint: NSLayoutConstraint!

 private var isResizing: Bool = false {
        didSet {
            [topLeftCircleView, topRightCircleView, bottomLeftCircleView, bottomRightCircleView, rotateButton, deleteButton].forEach { $0.isHidden = !isResizing }
            borderView.layer.borderWidth = isResizing ? 2.0 : 0.0
        }
    }

    private var originalImageFrame: CGRect = .zero
    private var resizeRect = ResizeRect()
    private var proxyFactor: CGFloat = 10.0

    private var rotationGesture: UIRotationGestureRecognizer!

override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .white

        setupView()
        addConstraintsForItems()
        createCircles()

        addTapGestureRecognizer()
        addPinchGestureRecognizer()
        addRotationGesture()
        addDeletePhotoButton()
    }

这是设置代码，以防万一您可能需要它。这里是约束代码：

private func addConstraintsForItems() {
        imageViewTopConstraint = imageView.topAnchor.constraint(equalTo: view.topAnchor, constant: 180)
        imageViewBottomConstraint = view.bottomAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 180)
        imageViewLeftConstraint = imageView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 60)
        imageViewRightConstraint = view.trailingAnchor.constraint(equalTo: imageView.trailingAnchor, constant: 70)

        NSLayoutConstraint.activate([imageViewTopConstraint, imageViewBottomConstraint, imageViewLeftConstraint, imageViewRightConstraint])

        let borderViewTopConstraint = borderView.topAnchor.constraint(equalTo: imageView.topAnchor)
        let borderViewLeftConstraint = borderView.leadingAnchor.constraint(equalTo: imageView.leadingAnchor)
        let borderViewRightConstraint = borderView.trailingAnchor.constraint(equalTo: imageView.trailingAnchor)
        let borderViewBottomConstraint = borderView.bottomAnchor.constraint(equalTo: imageView.bottomAnchor)

        NSLayoutConstraint.activate([borderViewTopConstraint, borderViewLeftConstraint, borderViewRightConstraint, borderViewBottomConstraint])

        rotateButtonBottomAnchorConstraint = rotateButton.centerYAnchor.constraint(equalTo: imageView.centerYAnchor, constant: -20)
        rotateButtonTrailingAnchorConstraint = rotateButton.trailingAnchor.constraint(equalTo: imageView.trailingAnchor, constant: 40)

        NSLayoutConstraint.activate([rotateButtonBottomAnchorConstraint, rotateButtonTrailingAnchorConstraint])

        deleteButtonTopAnchorConstraint = deleteButton.centerYAnchor.constraint(equalTo: imageView.centerYAnchor, constant: 20)
        deleteButtonTrailingAnchorConstraint = deleteButton.trailingAnchor.constraint(equalTo: imageView.trailingAnchor, constant: 40)

        NSLayoutConstraint.activate([deleteButtonTopAnchorConstraint, deleteButtonTrailingAnchorConstraint])
    }

下面是如何放大和旋转图像：

@objc private func handlePincheGesture(_ gestureRecognizer: UIPinchGestureRecognizer) {
        if gestureRecognizer.state == .began {
            isResizing = false
        }
        gestureRecognizer.view?.transform = (gestureRecognizer.view?.transform)!.scaledBy(x: gestureRecognizer.scale, y: gestureRecognizer.scale)
        gestureRecognizer.scale = 1.0
        if gestureRecognizer.state == .ended {
            isResizing = true
        }
    }

@objc private func handleRotationGesture(_ gestureRecognizer: UIRotationGestureRecognizer) {
        if gestureRecognizer.state == .began {
            isResizing = false
        }
        if let view = gestureRecognizer.view {
            view.transform = view.transform.rotated(by: gestureRecognizer.rotation)
            gestureRecognizer.rotation = 0
        }
        if  gestureRecognizer.state == .ended {
            isResizing = true
        }
    }

我应该怎么做才能正确放置按钮？
