如果我已经在使用控制器，如何显示Adyen结帐？

Question

我面临一个问题，我使用tableview作为侧边栏来从应用程序中显示某些控制器。尝试预设Adyen付款结帐时出现错误，告诉我我不能使用多页演示，我的问题是，如何解决此问题？

我曾想过在按下签出按钮后解开边栏，或者按下边栏并显示其他控制器，但是没有成功，或者我做错了。

谢谢！

这是放置在MainViewController中的侧面菜单按钮

public func setSideMenuButton()
    {
        let button = UIButton()
        button.frame = CGRect(x: self.view.frame.size.width - 65, y: self.view.frame.size.height - 160, width: 50, height: 50)
        button.setImage(#imageLiteral(resourceName: "side_menu_button").withRenderingMode(.alwaysOriginal), for: .normal)
        button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
        self.view.addSubview(button)

    }

    @objc func buttonAction(sender: UIButton!)
    {
        pauseEachExistingVideoPlayer()

        guard let sideMenuViewController = storyboard?.instantiateViewController(withIdentifier: "SideMenuViewController") as? SideMenuViewController else { return }

        sideMenuViewController.modalPresentationStyle = .overCurrentContext
        sideMenuViewController.transitioningDelegate = self
        present(sideMenuViewController, animated: true)
    } 

从表格中显示每个索引

 override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
    {

        switch indexPath.row {
        case 0: present( UIStoryboard(name: "Profile", bundle: nil).instantiateViewController(withIdentifier: "UserProfileVC") as UIViewController, animated: true, completion: nil)
        case 1: present( UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SR_VideoLibrary") as UIViewController, animated: true, completion: nil)
        case 2: present( UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SR_Livestream") as UIViewController, animated: true, completion: nil)
        case 3: return
        case 4: return
        case 5: present( UIStoryboard(name: "VideoLibrary", bundle: nil).instantiateViewController(withIdentifier: "ProjectsListVC") as UIViewController, animated: true, completion: nil)
        case 6: present( UIStoryboard(name: "Profile", bundle: nil).instantiateViewController(withIdentifier: "GetPremiumVC") as UIViewController, animated: true, completion: nil)

        default:
            break
        } 
    }

这是我在外面轻按时关闭约束视图并关闭侧边栏的方式

class SideMenuViewController: UIViewController, UITableViewDelegate
{
    @IBOutlet weak var modalView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        if let view = modalView
        {
            addTapGesture(target: view, action: #selector(dismissController))
        }

    }

    @objc private func dismissController()
    {
        dismiss(animated: true, completion: nil)
    }

}
extension SideMenuViewController {
    func addTapGesture(target: UIView, action: Selector, numberOfTaps: Int = 1) {
        let tap = UITapGestureRecognizer(target: self, action: action)
        tap.numberOfTapsRequired = numberOfTaps
        target.isUserInteractionEnabled = true
        target.addGestureRecognizer(tap)
    }
}

This is the side menu storyboard

[恐怕这是UIKit中的一个限制，一个View Controller只能显示另一个ViewController。

所以我怎么看，您有两种选择，要么先关闭已经显示的SideMenuViewController，要么让SideMenuViewController出现Adyen视图控制器。

[如果您使用的是Adyen checkout SDK 3.5.0，则将一个helper属性添加到UIViewController的每个实例中，该实例将获得展示次数最多的视图控制器，请使用MainViewController的此属性-或其他任何会使用的视图控制器呈现adyen结帐视图控制器很有意义-在其顶部呈现另一个。

presenterViewController.adyen.topPresenter.present(secondPresentedVC, animated: true)
如果使用的SDK版本中没有此adyen帮助器，则可以按如下方式实现UIViewController的扩展：

extension UIViewController {

    var topPresenter: UIViewController {
        var topController: UIViewController = self
        while let presenter = topController.presentedViewController {
            topController = presenter
        }
        return topController
    }

}
希望这会有所帮助！。
