快速自定义上下文菜单预览提供程序无法单击内部的任何视图(使用手势) [英] swift custom context menu previewprovider can not click any view inside(using tapgesture)

问题描述

我正在处理类似消息的反应，这就是我所做的(使用contextMenu中的customProvider)

im working with reaction like message, here is what i did (using customProvider from contextMenu)

下面是我将表情符号动作添加到customProvider控制器时的代码

below is the code when i added emoji action to customProvider controller

private func addReactionList(_ items : [Reaction]) -> UIView{
        let reactionView = UIView()
      
        
        var arrangedSubviews: [UIView] = []
        
        for reaction in items {
            let imgView = UIImageView(image: AppUtils.reactionToImage(reaction: reaction))
            imgView.isUserInteractionEnabled = true
            imgView.frame = CGRect(x: 0, y: 0, width: iconHeight, height: iconHeight)
            imgView.layer.cornerRadius = (imgView.frame.height) / 2
            imgView.layer.masksToBounds = true
            imgView.layer.borderColor = UIColor.clear.cgColor
            imgView.layer.borderWidth = 0
            imgView.contentMode = .scaleAspectFit
            imgView.restorationIdentifier = reaction.Type
            
            
            let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTapGesture(_:)))
            tapGesture.delegate = self
            tapGesture.numberOfTapsRequired = 1
            tapGesture.delaysTouchesBegan = true
            tapGesture.cancelsTouchesInView = false
            imgView.isUserInteractionEnabled = true
            imgView.addGestureRecognizer(tapGesture)
            
            arrangedSubviews.append(imgView)
        }
        
        let stackView = UIStackView(arrangedSubviews: arrangedSubviews)
        stackView.distribution = .fillEqually
        stackView.spacing = padding
        stackView.layoutMargins = UIEdgeInsets(top: padding, left: padding, bottom: padding, right: padding)
        stackView.isLayoutMarginsRelativeArrangement = true
        
        let width = (CGFloat(items.count) * iconHeight) + (CGFloat(items.count+1) * padding)
        reactionView.frame = CGRect(x: 0, y: 0, width: width, height: iconHeight + 2 * padding)
        reactionView.layer.cornerRadius = 12
        reactionView.addSubview(stackView)
        stackView.frame = reactionView.frame
        stackView.isUserInteractionEnabled = false
        reactionView.isUserInteractionEnabled = false
        
        return reactionView
    }

然后将其添加到自定义提供程序vc:

then i added this to custom provider vc:

let actionsReacts = addReactionList(likeReactions)
        let emojiReacts = addReactionList(emojiReactions)
        if let snap = customView.snapshotView(afterScreenUpdates: true) as UIView?{
            view.addSubview(snap)
            view.addSubview(actionsReacts)
            view.addSubview(emojiReacts)
            
            let maxWidth = snap.frame.size.width >= actionsReacts.frame.size.width ? snap.frame.size.width : actionsReacts.frame.size.width
            
            var currentSnapFrame = snap.frame
            currentSnapFrame = CGRect(Int((maxWidth - snap.frame.size.width)) / 2, 0 , Int(snap.frame.size.width), Int(snap.frame.size.height))
            snap.frame = currentSnapFrame
            
            var currentActionsReactFrame = actionsReacts.frame
            currentActionsReactFrame = CGRect(0, Int(snap.frame.size.height), Int(actionsReacts.frame.size.width), Int(actionsReacts.frame.size.height))
            actionsReacts.frame = currentActionsReactFrame
            
            var currentEmojiReactFrame = actionsReacts.frame
            currentEmojiReactFrame = CGRect(0, Int(snap.frame.size.height) + Int(emojiReacts.frame.size.height), Int(emojiReacts.frame.size.width), Int(emojiReacts.frame.size.height))
            emojiReacts.frame = currentEmojiReactFrame
            
            
            preferredContentSize = CGSize(width: maxWidth, height: snap.frame.size.height + actionsReacts.frame.size.height + emojiReacts.frame.size.height)
        }

但是手势无法触发，我尝试将img更改为按钮，但仍然无法点击

But the gesture can not fire, i tried to change img to button, but still not get click

@objc func handleTapGesture(_ sender : UITapGestureRecognizer){
        let tappedImage = sender.view as! UIImageView
        let reactionType = tappedImage.restorationIdentifier ?? ""
        onSelectedReaction?(reactionType)
    }
    
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        return true
    }
    
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }

我不知道为什么我不能在任何地方单击，即使我试图将手势单击添加到viewcontroller视图.有人可以解释吗?预先感谢

i do not know why i can not click any where, even i tried to add gesture click to viewcontroller view. Can anyone explain it? Thanks in advance

推荐答案

我更改为使用英雄动画呈现新的VC，这很无聊，但这是我目前的最佳选择

i changed to present new VC with hero animation, so bored, but it is my best choice for now
