iOS:如何在确认对话框后为UITableCell"删除"菜单中的隐藏设置动画？

Question

我有一个单元格删除句柄功能,提醒确认对话框,如果用户按"好",它将继续并删除单元格.否则,我希望它以编程方式隐藏删除按钮.我设置了以下函数来处理在UITableViewDelegate中删除UITableView单元格:

// delete a cell
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if(editingStyle == .Delete) {
        var deleteAlert = UIAlertController(
            title: "Delete?",
            message: "All data will be permanently deleted.",
            preferredStyle: UIAlertControllerStyle.Alert)
        deleteAlert.addAction(UIAlertAction(title: "Ok", style: .Default, handler: {
            (action: UIAlertAction!) in
            // delete logic here:
            self.deleteDataForCell(indexPath.row)
            self.myTable.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
            println("Delete successful")
        }))
        deleteAlert.addAction(UIAlertAction(title: "Cancel", style: .Default, handler: {
            (action: UIAlertAction!) in
            println("Delete cancelled")
            // TODO - now hide the delete button with animation
        }))
        presentViewController(deleteAlert, animated: true, completion: nil)
    }
}

"TODO"部分是我不知道如何强制表以编程方式隐藏删除按钮的地方.现在,删除按钮将保持在视图中,直到用户点击屏幕上的其他位置.我可以打电话,myTable.reloadData()但这不是动画.

找到一个使用此解决方案:

self.tableView.setEditing(false, animated: true)
