【中文标题】iOS 14 从 UIView 呈现 UIMenu

【英文标题】：iOS 14 present UIMenu from UIView

【问题描述】：

ios 14 的UIMenu 似乎可以从任何UIBarButtonItem 或UIButton / UIControl 呈现，但我将如何从通用UIView 呈现它？

【参考方案1】：

添加交互：

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

将 UIContextMenuInteractionDelegate 添加到您的控制器：

extension YourViewController: UIContextMenuInteractionDelegate 
               
      func contextMenuInteraction(_ interaction: UIContextMenuInteraction, configurationForMenuAtLocation location: CGPoint) -> UIContextMenuConfiguration? 
        return UIContextMenuConfiguration(identifier: nil, previewProvider: nil)  suggestedActions in
            
            // Create an action for sharing
            let share = UIAction(title: "Share", image: UIImage(systemName: "square.and.arrow.up"))  action in
                // Show system share sheet
            
    
            // Create an action for renaming
            let rename = UIAction(title: "Rename", image: UIImage(systemName: "square.and.pencil"))  action in
                // Perform renaming
            
    
            // Here we specify the "destructive" attribute to show that it’s destructive in nature
            let delete = UIAction(title: "Delete", image: UIImage(systemName: "trash"), attributes: .destructive)  action in
                // Perform delete
            
    
            // Create and return a UIMenu with all of the actions as children
            return UIMenu(title: "", children: [share, rename, delete])
        
    

现在，长按视图并查看您的菜单 :)

如果没有完全清楚，我深表歉意，我希望通过一个通用的UIView 呈现菜单没有长按。
