通过轻触在集合视图中隐藏动画ImageView

// 在集合视图的代理方法中添加手势识别器
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! CustomCell
    
    // 添加轻触手势识别器
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))
    cell.addGestureRecognizer(tapGesture)
    
    return cell
}

// 轻触手势的处理方法
@objc func handleTap(_ gesture: UITapGestureRecognizer) {
    guard let cell = gesture.view as? CustomCell else { return }
    
    // 获取被轻触的单元格的索引路径
    guard let indexPath = collectionView.indexPath(for: cell) else { return }
    
    // 获取单元格中的UIImageView
    let imageView = cell.imageView
    
    // 使用动画隐藏UIImageView
    UIView.animate(withDuration: 0.3, animations: {
        imageView.alpha = 0
    }) { _ in
        // 动画结束后，将UIImageView从父视图中移除
        imageView.removeFromSuperview()
    }
