Tap 在 didSelectItemAt 中不起作用，它不响应任何内容。谁能帮我看看这个问题？

Question

这是我的完整代码。 MenuTableViewCell 是从另一个控制器调用的。它显示了数据和图片。但是当点击某个部分时，点击不起作用。点击后它应该转到不同的视图控制器。一切都必须以编程方式完成。

#MenuTableViewCell.swift

导入 UIKit

class MenuTableViewCell：UITableViewCell、UICollectionViewDelegate、UICollectionViewDataSource、UICollectionViewDelegateFlowLayout {

var Labeltitle: UILabel?
var colView: UICollectionView?
//屏幕宽度
let SCREEN_WIDTH = UIScreen.main.bounds.width
//屏幕高度
let SCREEN_HEIGHT = UIScreen.main.bounds.height

var arrData = ["旅游英语","商务英语","基础英语","成人英语","少儿英语","青少英语","视频","师资"]

var collectionViewHeight: NSLayoutConstraint?

override func awakeFromNib() {
    super.awakeFromNib()


}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)!
}

override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)
    // 设置选中cell时无高亮等效果
    self.selectionStyle = .none

    let layout = UICollectionViewFlowLayout()
    self.colView = UICollectionView(frame: CGRect.init(x: 0, y: 0, width: SCREEN_WIDTH, height: 680), collectionViewLayout: layout);
    self.colView?.register(MenuCollectionViewCell.self, forCellWithReuseIdentifier: "colCell")
    self.colView?.delegate = self
    self.colView?.dataSource = self
    self.colView?.backgroundColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
    self.colView?.showsHorizontalScrollIndicator = true
    self.colView?.allowsSelection = true
    
    self.colView?.allowsMultipleSelection = true
    
    //设置间距
    
    //设置水平间距
    layout.minimumInteritemSpacing = 0;
    //设置垂直间距
    layout.minimumLineSpacing = 0;
    
    
    //   layout.itemSize = CGSize(width: (SCREEN_WIDTH/3), height: 125)
    layout.itemSize = CGSize(width: (SCREEN_WIDTH/2), height: 170)
    
    
    self.contentView.addSubview(colView!)

}
//加载数据
func reloadData() {
    //collectionView重新加载数据
    self.colView?.reloadData()
    //更新collectionView的高度约束
    let contentSize = self.colView?.collectionViewLayout.collectionViewContentSize
    self.collectionViewHeight?.constant = contentSize!.height
}

这是屏幕截图 When I tap anyone of this section, nothing happens. didSelectItemAt does not get called.

所以当我点击图片的某个项目时，水龙头不起作用。我已尝试将解决方案 self.colView?.isUserInteractionEnabled 设置为 true 或 false。但它没有用。 Collectionview cellForItemAt 有效。但是 collectionview didSelectItemAt 不起作用。我真的不知道如何让水龙头工作。谁能帮帮我？

用视图调试器进行视图调试后，我发现有新层UITableViewCellContent。这在更新 xcode 后出现。 self.addSubview(colView!) 而不是 contentView.addSubview(colView!) 解决了问题。

Tap 在 didSelectItemAt 中不起作用，它不响应任何内容。谁能帮我看看这个问题？

Tap does not work inside didSelectItemAt, it does not response to anything. Can anyone help me to look at this issue?
