在类似于 ios 通知中心的表格视图中编辑操作

我最终创建了自己的视图作为表格视图单元格的一部分并添加了自定义动画..

示例代码：
在我的 tableViewController 中：

override func viewDidLoad() {
    super.viewDidLoad()
    ....

    let tapGesture = UITapGestureRecognizer.init(target: self, action: #selector(handleTap))
    tableView.addGestureRecognizer(tapGesture)

    let leftSwipeGesture = UISwipeGestureRecognizer.init(target: self, action: #selector(handleLeftSwipe(_:)))
    leftSwipeGesture.direction = .left
    tableView.addGestureRecognizer(leftSwipeGesture)

    let rightSwipeGesture = UISwipeGestureRecognizer.init(target: self, action: #selector(handleRightSwipe(_:)))
    rightSwipeGesture.direction = .right
    tableView.addGestureRecognizer(rightSwipeGesture)
}

func handleTap(_ gestureRecognizer: UISwipeGestureRecognizer) {
    let point = gestureRecognizer.location(in: self.tableView)
    if let indexPath = self.tableView.indexPathForRow(at: point) {
        var shouldSelectRow = false
        if indexPathBeingEdited != nil {
            if indexPath == indexPathBeingEdited {
                shouldSelectRow = true
            } else {
                //handle close of the cell being edited already
                if let previousEditedCell = tableView.cellForRow(at: indexPathBeingEdited!) as? NotificationCenterTableViewCell {
                    previousEditedCell.closeEditActions()
                    indexPathBeingEdited = nil
                }
            }
        } else {
            shouldSelectRow = true
        }
        if shouldSelectRow {
            tableView.selectRow(at: indexPath, animated: true, scrollPosition: .middle)
            tableView(tableView, didSelectRowAt: indexPath)
        }
    }
}

func handleLeftSwipe(_ gestureRecognizer: UISwipeGestureRecognizer) {
    let point = gestureRecognizer.location(in: self.tableView)
    if let indexPath = self.tableView.indexPathForRow(at: point) {
        if indexPathBeingEdited != nil {
            if indexPath == indexPathBeingEdited {
                //Do nothing
            } else {
                //handle close of the cell being edited already
                if let previousEditedCell = tableView.cellForRow(at: indexPathBeingEdited!) as? NotificationCenterTableViewCell {
                    previousEditedCell.closeEditActions()
                    indexPathBeingEdited = nil
                }
            }
        }
        //proceed with left swipe action
        if let cell = tableView.cellForRow(at: indexPath) as? NotificationCenterTableViewCell {
            cell.handleLeftSwipe(gestureRecognizer)
            let notification = notificationsArray[indexPath.section].notificationItems[indexPath.row]

            //Update the title of Read button
            if notification.isNotificationRead {
                cell.readUnreadButtonLabel.text = "Unread"
            } else {
                cell.readUnreadButtonLabel.text = "Read"
            }
            indexPathBeingEdited = indexPath
        }
    }
}

func handleRightSwipe(_ gestureRecognizer: UISwipeGestureRecognizer) {
    let point = gestureRecognizer.location(in: self.tableView)
    if let indexPath = self.tableView.indexPathForRow(at: point) {
        if indexPathBeingEdited != nil {
            if indexPath == indexPathBeingEdited {
                if let cell = tableView.cellForRow(at: indexPath) as? NotificationCenterTableViewCell {
                    cell.closeEditActions()
                    indexPathBeingEdited = nil
                    //Update the title of Read button
                    cell.readUnreadButtonLabel.text = "Read"
                }
            } else {
                //handle close of the cell being edited already
                if let previousEditedCell = tableView.cellForRow(at: indexPathBeingEdited!) as? NotificationCenterTableViewCell {
                    previousEditedCell.closeEditActions()
                    indexPathBeingEdited = nil
                    //Update the title of Read button
                    previousEditedCell.readUnreadButtonLabel.text = "Read"
                }
            }
        }
    }
}

在我的表格视图单元格中：

    func handleLeftSwipe(_ gestureRecognizer: UISwipeGestureRecognizer) {
    if !isBeingEdited {
        //Action to open the edit buttons
        UIView.animate(withDuration: 0.5, animations: {
            self.notificationHolderViewLeadingConstraint.constant -= 248
            self.notificationHolderViewTrailingConstraint.constant -= 248

            self.editActionsView.isHidden = false
            self.layoutIfNeeded()
        }, completion: { (success) in

        })
        isBeingEdited = true
    }
}

func closeEditActions() {
    if isBeingEdited {
        //Action to open the edit buttons
        UIView.animate(withDuration: 0.5, animations: {
            self.notificationHolderViewLeadingConstraint.constant += 248
            self.notificationHolderViewTrailingConstraint.constant += 248

            self.editActionsView.isHidden = true
            self.layoutIfNeeded()
        }, completion: { (success) in

        })
        isBeingEdited = false
    }
}   


 override func draw(_ rect: CGRect) {
    if let viewToRound = editActionsView {
        let path = UIBezierPath(roundedRect:viewToRound.bounds,
                                byRoundingCorners:[.topRight, .topLeft, .bottomRight, .bottomLeft],
                                cornerRadii: CGSize(width: 20, height:  20))

        let maskLayer = CAShapeLayer()

        maskLayer.path = path.cgPath
        viewToRound.layer.mask = maskLayer
    }
}    

仅供参考，我有我的编辑按钮，即阅读/查看/清除添加到editActionsView。相应的操作与我的 tableViewCell 类中的 IBActions 相关联。

结果是这样的：
