打开上下文菜单上的快速编程UI UIContextMenuInteraction自动布局错误(groupView)

Question

我有一个程序界面的应用程序(没有故事板)。我将上下文菜单添加到视图控制器的一个按钮中。在打开这个菜单(点击并按住按钮)时，我在控制台中得到一个LayoutConstraints警告/错误(否则菜单工作得很好：

(
    "<NSAutoresizingMaskLayoutConstraint:0x600001c9ed50 h=--& v=--& UIInterfaceActionGroupView:0x7f9d4478ceb0.height == 0   (active)>",
    "<NSLayoutConstraint:0x600001cd7c50 groupView.actionsSequence....height >= 66   (active, names: groupView.actionsSequence...:0x7f9d4610ee00 )>",
    "<NSLayoutConstraint:0x600001cb3de0 UIInterfaceActionGroupView:0x7f9d4478ceb0.top == _UIContentConstraintsLayoutGuide:0x7f9d4478bba0''.top   (active)>",
    "<NSLayoutConstraint:0x600001cb3e80 V:[_UIContentConstraintsLayoutGuide:0x7f9d4478bba0'']-(0)-|   (active, names: '|':UIInterfaceActionGroupView:0x7f9d4478ceb0 )>",
    "<NSLayoutConstraint:0x600001cad090 groupView.actionsSequence....top == _UIContentConstraintsLayoutGuide:0x7f9d4478bba0''.top   (active, names: groupView.actionsSequence...:0x7f9d4610ee00 )>",
    "<NSLayoutConstraint:0x600001cad130 groupView.actionsSequence....bottom == _UIContentConstraintsLayoutGuide:0x7f9d4478bba0''.bottom   (active, names: groupView.actionsSequence...:0x7f9d4610ee00 )>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x600001cd7c50 groupView.actionsSequence....height >= 66   (active, names: groupView.actionsSequence...:0x7f9d4610ee00 )>

这个groupView不是我的一个视图！我已经在所有自定义控件(标签、字段等)上设置了translatesAutoresizingMaskIntoConstraints = false。我想我需要将它设置为上下文菜单的某个位置，但我不知道如何设置，也不知道在哪里。

相关守则：

在我的视图控制器中：

        let interaction = UIContextMenuInteraction(delegate: self)
        annotationTypeButton.addInteraction(interaction)

代表分机：

//MARK: - UIContextMenuInteractionDelegate
extension AnnotationDetailsViewController: UIContextMenuInteractionDelegate {
    func contextMenuInteraction(_ interaction: UIContextMenuInteraction, configurationForMenuAtLocation location: CGPoint) -> UIContextMenuConfiguration? {
        return UIContextMenuConfiguration(identifier: "annotationTypeMenu" as NSCopying, previewProvider: nil) { _ in
            let children: [UIMenuElement] = self.makeAnnotationTypeActions()
            return UIMenu(title: "", children: children)
        }
    }
    
    func makeAnnotationTypeActions() -> [UIAction] {
        var actions = [UIAction]()
        for type in AnnotationType.allCases {
            actions.append( UIAction(title: type.rawValue, image: type.image, identifier: nil, attributes: []) { _ in
                let annotationType = AnnotationType(rawValue: type.rawValue) ?? AnnotationType.tips
                self.annotation.type = annotationType
                self.configureAnnotationTypeButton(with: annotationType)
            })
        }
        return actions
    }
}

任何帮助都很感激！

我在苹果开发者论坛上得到了一个答案，说布局警告是一个已知的问题，将在iOS14中解决！
