swift UITableViewCell 策划删除，iOS11之后 设置侧滑不到最左边

 

 

    /**侧滑删除实现的三个方法：
     *  canEditRowAt :设为true 才能侧滑或其他操作
     *  editActionsForRowAt (11之前侧滑删除)
     *  trailingSwipeActionsConfigurationForRowAt (11之后的侧滑删除)
     */
    //canEditRowAt :设为true 才能侧滑或其他操作
    @objc optional func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool
    
    /// 11之前侧滑删除
    @objc optional func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]?
    
    ///11之后的侧滑删除
    @available(iOS 11.0, *)
    @objc optional func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?

 

 

    func tableViewl(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
//显示/隐藏
        let showStateAction = UITableViewRowAction.init(style: .default, title: showStateTitle) { [weak self] (res, index) in
            }
        }
        showStateAction.backgroundColor = UIColor.red

        //1删除
        let deleteAction = UITableViewRowAction(style: UITableViewRowAction.Style.default, title: "删除") { [weak self] (res, index) in
        }
        deleteAction.backgroundColor = UIColor.green
        return [showStateAction, deleteAction]
    }

 

 

在iOS11之后多了一个方法，并且 侧滑会直接 左滑到底， 造成误删除， 需要禁用

UISwipeActionsConfiguration的performsFirstActionWithFullSwipe 属性，改为false

    //尾部滑动事件按钮（左滑按钮）
        @available(iOS 11.0, *)
        func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {

            let showStateAction = UIContextualAction(style: UIContextualAction.Style.destructive, title: "文字") { [weak self](action:UIContextualAction, view:UIView, handle:@escaping (Bool) -> Void) in

            }
            showStateAction.backgroundColor = UIColor.init(hexString: "#D1D1D1")

            //删除
            let  deleteAction = UIContextualAction(style: UIContextualAction.Style.destructive, title: "删除") { [weak self](acction:UIContextualAction, view:UIView, handle:@escaping (Bool) -> Void) in

            }
            deleteAction.backgroundColor = UIColor.init(hexString: "#F53943")

            //destructive图片
            let  destructiveImageAction = UIContextualAction(style: UIContextualAction.Style.destructive, title: nil) { [weak self](acction:UIContextualAction, view:UIView, handle:@escaping (Bool) -> Void) in
                self?.deleteOrder(by: indexPath.section)
            }
            if let ima = UIImage.init(named: "tempOrderDelete"){
                ///设置图片
                destructiveImageAction.image = ima
                ///和cell背景色一样就可以
                destructiveImageAction.backgroundColor  = UIColor.init(red: 195, green: 76, blue: 93, alpha: 1)
            }

            let configuration =  UISwipeActionsConfiguration(actions: [showStateAction, deleteAction, destructiveImageAction])
            configuration.performsFirstActionWithFullSwipe = false
            return configuration
        }
