推荐答案

是的，你可以这样做：

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {                  if (navigationType == UIWebViewNavigationType.FormSubmitted) { let VC = self.storyboard?.instantiateViewControllerWithIdentifier("myViewControllerName") as? myViewControllerName let navigationController = UINavigationController(rootViewController: VC!) self.navigationController?.presentViewController(navigationController, animated: true, completion:nil)              }         return true     }
