ios – 集合视图单元格在swift中慢速检测所选项目

我将集合视图放入表格视图单元格,我使它可以显示在单元格上,但是当我想选择集合单元格(更改颜色或打印单元格编号)时,选择功能不起作用,我需要多次点击该单元格以使其被选中.为什么单元格慢速检测所选项目？什么代码会影响要选择的单元格？

这是选择集合单元格的代码

override func awakeFromNib() {
    super.awakeFromNib()

    let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    let width = UIScreen.main.bounds.width
    layout.scrollDirection = .vertical
    layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
    layout.itemSize = CGSize(width: width/5, height: width/4)
    layout.minimumInteritemSpacing = 0
    layout.minimumLineSpacing = 0
    collectionView?.collectionViewLayout = layout
    collectionView?.delaysContentTouches = false

}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionViewCell", for: indexPath) as! CategoryCollectionViewCell
    cell.cateImg.image = imageName[indexPath.row]
    cell.cateLabel.text! = nameArray[indexPath.row]
    return cell
}

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    if let cell = collectionView.cellForItem(at: indexPath) as? CategoryCollectionViewCell {
        cell.cateImg.image = imageName2[indexPath.row]
        print("collectionViewCell selected \(indexPath)")
    }
}

func collectionView(_ collectionView: UICollectionView, didDeselectItemAt indexPath: IndexPath) {
    if let cell = collectionView.cellForItem(at: indexPath) as? CategoryCollectionViewCell {
        cell.cateImg.image = imageName[indexPath.row]
    }
}

AddViewCell.swift上的问题

我在AddViewController上删除此代码后修复了问题.

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(AddExpenseVC.dismissKeyboard))
view.addGestureRecognizer(tap)

@objc func dismissKeyboard() {
    view.endEditing(true)
}
