UITableViewRowAction : Delete

Question

我想让用户能够在我执行删除滑动操作时删除表格单元格，但我不知道如何实际删除所选单元格!如您所知，我正在使用 Swift 和 Xcode 6.3.1 编程

var deleteAction = UITableViewRowAction(style: .Default, title: "Delete") { (action, indexPath) -> Void in
            tableView.editing = false
            println("deleteAction")
            }

如果你想从 tableView 中完全删除一个单元格，那么你也必须将它从你的表数组中删除。考虑以下代码:

var deleteAction = UITableViewRowAction(style: .Default, title: "Delete") { (action, indexPath) -> Void in
        tableView.editing = true
            // Remove it from your TableArray and If it is stored into any local storage then you have to remove it from there too because if you doesn't remove it from your local storage then when you reload your tableview it will appears back

            self.tableData.removeAtIndex(indexPath.row) 

            tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic)

    }

    return [deleteAction]
}
