ios - tableViewvisibleCells swift 上缺少单元格

Question

当我滚动到 tableView 中的第二行后在 tableView 中看到可见单元格时，它给了我一个缺少的单元格，有 8 个单元格，它给了我 7 个单元格，这是我的代码

if response.count > 1
    {
        let index = IndexPath(row: 1, section: 0)
        self.tableView.scrollToRow(at: index, at: .top, animated: false)
    }
    if let _ = self.tableView {
        let cells = self.tableView.visibleCells
        UIView.animate(views: cells, animations: [], reversed: false, initialAlpha: 0, finalAlpha: 1, delay: 0, animationInterval: 0.1, duration: ViewAnimatorConfig.duration, options: UIView.AnimationOptions.allowAnimatedContent, completion: nil)
    }

我没有您正在使用的“ViewAnimator”，因此我无法测试它，但这应该适合您:

    if response.count > 1 {

        let index = IndexPath(row: 1, section: 0)
        self.tableView.scrollToRow(at: index, at: .top, animated: false)

        UIView.animate(withDuration: 0.1, animations: {
            self.tableView.layoutIfNeeded()
        }, completion: {
            _ in

            let cells = self.tableView.visibleCells

            // un-comment to output the array of visible cells
            // to debug console to confirm the desired rows are visible
            //print(cells)

            UIView.animate(views: cells, animations: [], reversed: false, initialAlpha: 0, finalAlpha: 1, delay: 0, animationInterval: 0.1, duration: ViewAnimatorConfig.duration, options: UIView.AnimationOptions.allowAnimatedContent, completion: nil)
        })

    }
