Why not able to navigate from WKWebView delegate method "didFinish" in swift

问题

我在网页中显示了CCavenue网址，而且我的所有WKWebView委托方法都被调用了，但问题是我无法从didFinish方法中导航到另一个视图控制器。

**代码：**我像这样呈现CCAvenuePaymentWebviewVC

  1. let vc = Helper.getVcObject(vcName: .CCAvenuePaymentWebviewVC, storyboardName: .Miscellaneous) as! CCAvenuePaymentWebviewVC
  2.                 
  3. vc.studentId = myId
  4. vc.modalPresentationStyle =  .pageSheet
  5. self.present(vc, animated: false, completion: nil)

这里是CCAvenuePaymentWebviewVC的代码，当我打印时，我能够打印出来，但无法进入MyFollowersViewController，为什么？我哪里错了，请指导我。

在条件内部：

  1. import UIKit
  2. import WebKit
  3. class CCAvenuePaymentWebviewVC: UIViewController, WKNavigationDelegate {
  5. @IBOutlet weak var webView: WKWebView!
  7. override func viewDidLoad() {
  8.     super.viewDidLoad()
  9.     webView.navigationDelegate = self
  10.     loadRequestOnWebView()
  11. }
  13. private func loadRequestOnWebView(){
  14.     
  15.     var apiUrl = "https://project.in/dev/api/student/workshop-payment-initiate-new?workshop_id="
  16.     
  17.     let myURL = URL(string: apiUrl)
  18.     var myRequest = URLRequest(url: myURL!)
  19.     myRequest.httpMethod = "post"
  20.     DispatchQueue.main.async {
  21.         self.webView.load(myRequest)
  22.     }
  23. }
  25. @IBAction func backNavigationButton(_ sender: UIButton) {
  26.     self.dismiss(animated: true, completion: nil)
  27. }
  29. func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
  30.     print("finish to load")
  31.     
  32.     if let urlAsString = webView.url?.absoluteString{
  33.         let redirectURL = "https://k12studio.in/dev/payment-success"
  34.         
  35.         if urlAsString.contains(redirectURL)  {
  36.             
  37.             print("inside the condition")
  38.             let vc = Helper.getVcObject(vcName: .MyFollowersViewController, storyboardName: .Miscellaneous) as! MyFollowersViewController
  39.             self.navigationController?.pushViewController(vc, animated: true)
  40.         }
  41.     }
  42. }
  43. }

希望对你有所帮助。

你不能在已呈现的视图控制器上叠加另一个视图控制器。您需要将一个UINavigationController附加到您的CCAvenuePaymentWebviewVC。

尝试这样做：

  1. let vc = Helper.getVcObject(vcName: .CCAvenuePaymentWebviewVC, storyboardName: .Miscellaneous) as! CCAvenuePaymentWebviewVC
  2. vc.studentId = myId
  3. let navController = UINavigationController(rootViewController: vc)
  4. navController.modalPresentationStyle = .fullScreen
  5. self.present(navController, animated: true, completion: nil)
英文:

You cannot push a ViewController over a presented ViewController. What you need is to attach a UINavigationController to your
CCAvenuePaymentWebviewVC

Try this:

  1. let vc = Helper.getVcObject(vcName: .CCAvenuePaymentWebviewVC, storyboardName: .Miscellaneous) as! CCAvenuePaymentWebviewVC
  2. vc.studentId = myId
  3. let navController = UINavigationController(rootViewController: vc)
  4. navController.modalPresentationStyle = .fullScreen
  5. self.present(navController, animated: true, completion: nil)
