您需要记录单元格的动画是为您可以维护一个数组...
为此创建属性。

var arrIndexPath = [IndexPath]()

字符串
然后执行以下操作：

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
     
if arrIndexPath.contains(indexPath) == false {
        cell.alpha = 0
        let transform = CATransform3DTranslate(CATransform3DIdentity, 0, 200, 0)
        cell.layer.transform = transform
        
        UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {
            cell.alpha = 1
            cell.layer.transform = CATransform3DIdentity
        })
        
        arrIndexPath.append(indexPath)
    }
}

你可以在ViewController中添加一个数组，例如每个单元格都有bool标志。

var cellAnimationsFlags = Array(repeatElement(false, count: yourDataSourceArray.count))

字符串
然后检查一下：

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    if self.cellAnimationsFlags[indexPath.row] {
        return
    }
    cell.alpha = 0
    let transform = CATransform3DTranslate(CATransform3DIdentity, 0, 200, 0)
    cell.layer.transform = transform
    self.cellAnimationsFlags[indexPath.row] = true

    UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {
        cell.alpha = 1
        cell.layer.transform = CATransform3DIdentity
    })
}
