如果我已经在展示控制器，如何展示 Adyen 结帐？

Question

我遇到了一个问题，我使用 tableview 作为侧边栏来展示应用程序中的某些控制器。当尝试为付款预设 Adyen 结帐时，出现一个错误，告诉我我不能使用多重呈现，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，或者按下侧边栏并展示其他控制器，但没有成功，或者我做得不对。

谢谢！

这是放在 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
        } 
    }

这就是我在外面点击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 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，则会向 UIViewController 的每个实例添加一个辅助属性，该属性会获取最顶部的视图控制器，请使用 MainViewController 的此属性 - 或任何其他视图控制器显示 adyen 结帐视图控制器是有意义的 - 在它之上显示另一个。

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

如果您使用的 SDK 版本中没有此 adyen 帮助器，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
    }

}

希望这会有所帮助！
