如果我已经展示控制器，如何展示 Adyen 结账？

Question

我遇到了一个问题，我正在使用 tableview 作为侧边栏来显示应用程序中的某些控制器。尝试为付款预设 Adyen 结账时出现错误，提示我无法使用多显示，我的问题是，我该如何解决这个问题？

我想在按下结帐按钮后关闭侧边栏，或者按下侧边栏并显示其他控制器，但没有成功，或者我没有做对。

谢谢！

这是放置在 MainViewController 中的侧边菜单按钮

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)
    }

显示表格中的每个索引

 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
        } 
    }

这就是我在外部点击时关闭容器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 的一个限制，一个 View Controller 只能呈现另一个 ViewController。

所以我怎么看，你有两个选择，要么首先关闭已经呈现的 SideMenuViewController，要么让 SideMenuViewController 呈现 Adyen 视图控制器。

如果您使用的是 Adyen checkout SDK 3.5.0，则在 UIViewController 的每个实例中都添加了一个助手属性来获取最上面显示的视图控制器，请使用此 [= MainViewController 的 27=] - 或任何其他对呈现 adyen 结帐视图控制器有意义的视图控制器 - 在其上呈现另一个视图控制器。

presenterViewController.adyen.topPresenter.present(secondPresentedVC, animated: true)

如果您使用的 SDK 版本中没有此 adyen 帮助程序，您可以实现 UIViewController 的扩展，如下所示：

extension UIViewController {

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

}

希望对您有所帮助！
