点击通知时推送视图控制器-解网

问：

我有一个 Storyboard 应用程序，其中 UINavigationController 作为其 Storyboard 入口点。它的正常主视图是一个名为“ViewController”的 ViewController。我希望在用户点击传入通知时推送名为“JustNotifications”的控制器。但是，到目前为止，什么也没发生。我错过了什么？

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler {
    NSDictionary *notificationData = response.notification.request.content.userInfo;
    
    // Extract data from the notification payload
    NSString *title = notificationData[@"title"];
    NSString *description = notificationData[@"description"];

    // Get a reference to the navigation controller
    UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;

    // Find the currently visible view controller in the navigation stack
    UIViewController *currentViewController = navigationController.visibleViewController;

    // Perform the segue
    [currentViewController performSegueWithIdentifier:@"ShowJustNotificationsSegue" sender:self];

    // Call the completion handler
    completionHandler();
}

    JustNotifications *newViewController = [mainStoryboard instantiateViewControllerWithIdentifier:@"JustNotifications"];
    newViewController.titleText = title;
    newViewController.descriptionText = description;
    
    // Wrap the JustNotifications view controller in a new navigation controller
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:newViewController];
    
    // Present the navigation controller modally
    UIViewController *rootViewController = UIApplication.sharedApplication.keyWindow.rootViewController;
    [rootViewController presentViewController:navController animated:YES completion:nil];
    
    completionHandler();
}
