Question

我有一个UITableViewRowAction所以当我滑动时，我可以选择3个选项。如果我点击Call按钮，我想要一个新的ViewController来弹出整个屏幕。如果我点击新ViewController 内的按钮，我希望将其解除。

单击“调用”按钮，将ViewController打开为弹出窗口

点击按钮后会打开，点击底部的x按钮就会解除此问题

这是我的代码

func buttonToDismiss (sender: AnyObject) {

    self.presentedViewController?.dismiss(animated: true, completion: nil)
}


func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

    let callButton = UITableViewRowAction(style: .default, title: "Call", handler: { (action, indexPath) in
        self.tableView.dataSource?.tableView?(
            self.tableView,
            commit: .delete,
            forRowAt: indexPath)

        let vc = UIViewController(nibName: nil, bundle: nil)
        vc.view.frame = CGRect(x: 0, y: 0, width: 100, height: 200)
        vc.view.backgroundColor = UIColor(red: 62/255.0, green: 70/255.0, blue: 80/255.0, alpha: 1.0)
        vc.modalPresentationStyle = .popover


        let declineButton = UIButton()
        declineButton.frame = CGRect(x: 150, y: 484, width: 75, height: 75)
        declineButton.backgroundColor = UIColor(red: 36/255.0, green: 44/255.0, blue: 55/255.0, alpha: 1.0)
        declineButton.tintColor = UIColor.white
        declineButton.layer.cornerRadius = declineButton.frame.size.height / 2
        declineButton.layer.masksToBounds = true
        declineButton.clipsToBounds = true
        declineButton.setTitle("X", for: .normal)
        declineButton.addTarget(self, action: Selector(("buttonToDismiss:")), for: UIControlEvents.touchUpInside)
        vc.view.addSubview(declineButton)
        let popover = vc.popoverPresentationController!
        let cell = tableView.cellForRow(at: indexPath)!

        var cellAbsolutePosition = cell.superview!.convert(cell.frame.origin, to: nil)
        cellAbsolutePosition.x = cell.frame.width - 60
        popover.sourceRect = CGRect(origin: cellAbsolutePosition, size: cell.frame.size)
        popover.sourceView = tableView

        self.present(vc, animated: true, completion: nil)

        return
    })

我知道代码是我认为非常混乱，但我还不是很擅长编程应用程序。

我感谢您的帮助，并提前感谢您的努力。

Answer 1

这样做而不是你在做什么：

创建选择SELECT c0.*, p1."id" FROM "c0" AS c0 LEFT JOIN "p1" AS p1 ON p1."id" = 2 LEFT JOIN "c2" AS c2 ON c2."p1" = p1."id" WHERE (c2."c1_id" = c0."id") GROUP BY c0."id", p1."id"时要显示的ViewController
将call action按钮放在dismiss上并将其连接到ViewController
当用户选择IBAction时，从call action实例化ViewController并简单地展示

这是一个简单的例子：

说这是触发呼叫操作时要显示的storyboard

在ViewController

ViewController

call action

只需使用func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? { var rowActions = [UITableViewRowAction]() let callAction = UITableViewRowAction.init(style: .default, title: "Call") { (action, cellPath) in //instantiate the view controller with storyboard ID let vc = self.storyboard?.instantiateViewController(withIdentifier: "DetailViewController") as! DetailViewController self.present(vc, animated: true, completion: { }) } rowActions.append(callAction) return rowActions }

IBAction

试试这段代码：在Swift 3中测试。

<强> MainVC：

  func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
  }

  func tableView(_ tableView: UITableView, shouldShowMenuForRowAt indexPath: IndexPath) -> Bool {
    return true
  }

  func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

    let callAction = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Call") { (UITableViewRowAction, NSIndexPath) -> Void in
        self.performSegue(withIdentifier: "callSegue", sender: self) 
    }

    let videoAction = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Video") { (UITableViewRowAction, NSIndexPath) -> Void in
    }

    let deleteAction = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Delete") { (UITableViewRowAction, NSIndexPath) -> Void in  
    }

    callAction.backgroundColor = .blue
    videoAction.backgroundColor = .green
    deleteAction.backgroundColor = .red

    return [deleteAction,videoAction,callAction]

}

@IBAction func dissmissButton(_ sender: UIButton) {

    dismiss(animated: true, completion: nil)
}

我想通过UITableViewRowButtonAction打开一个新的ViewController
