func animationTable() {
    
self.tableView.reloadData()
    
let cells = tableView.visibleCells
let tableHeight: CGFloat = tableView.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(1.0, delay: 0.05 * Double(index), usingSpringWithDamping: 0.8, initialSpringVelocity: 0, options: [], animations: {
cell.transform = CGAffineTransformMakeTranslation(0, 0);
}, completion: nil)
    
index += 1
}
    }

然后在viewWillAppear中调用它
