ios – UITableView.visibleCells没有捕获所有可见的单元格

这是因为UITableView.visibleCells最后没有返回此单元格. (它返回单元格0-12,最后一个单元格位于索引13并且清晰可见)

这是代码.有什么我可以做的,以确保所有单元格动画？

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    tableView.reloadData()

    let cells = tableView.visibleCells
    let tableHeight: CGFloat = clubsTable.bounds.size.height

    for i in cells {
        let cell: UITableViewCell = i as UITableViewCell
        cell.transform = CGAffineTransformMakeTranslation(0,tableHeight)
    }


    var index = 0

    for a in cells {
        let cell: UITableViewCell = a as UITableViewCell

        UIView.animateWithDuration(1.5,delay: 0.05 * Double(indeX),usingSpringWithDamping: 0.8,initialSpringVeLocity: 0,options: UIViewAnimationOptions.CurveEaseIn,animations: {
            cell.transform = CGAffineTransformMakeTranslation(0,0);
            },completion: { (completE) in

        })

        index += 1
    }
}
