Question

我想在电子邮件中发送一个链接来启动特定的UIViewController（它实际上是一个UITableViewController）。我可以使用CustomURL方案从链接打开我的应用程序，我已经编写了URLHandler方法（最新的方法而不是已弃用的方法），我可以解析URL，但我无法打开页面。我正在使用故事板，以及UINavigatorController和UITabBarController。我要打开的场景的StoryboardID是“ApprovalView”。

当我运行以下代码时，出现以下错误：

UIViewControllerHierarchyInconsistency'，原因：'视图一次只能与一个视图控制器关联！查看; layer =; contentOffset：{0,0}＆gt;与....关联

我现在正在应用程序中运行它。如果我实际点击URL链接，应用程序就会挂起。

我查看了有关此错误的其他StackOverflow帖子，这似乎意味着我已经将视图连接到两个viewControllers。我认为那是因为这条线

ApprovalViewController * appViewController = [storyboard instantiateViewControllerWithIdentifier：@“ApprovalView”];

然而，建议的解决方案似乎不起作用，我相信因为我使用的是右舷。我可以打电话给我的segue吗？

非常感谢任何帮助！

    - (BOOL)application:(UIApplication *)application
                  openURL:(NSURL *)url
        sourceApplication:(NSString *)sourceApplication
               annotation:(id)annotation {

      // Get the host and query
      // the host is what expense to go to and the query is the noteID
      NSString *tmpHost = [[NSString alloc] init];
      tmpHost = [[url host] substringFromIndex:1];
      NSString *tmpQuery = [[NSString alloc] init];
      tmpQuery = [url query];

      // Go to a page

      // UIViewController *expenditureView =
      //      [storyboard instantiateViewControllerWithIdentifier:@"ApprovalView"];

      // UINavigationController *navVC = [[UINavigationController alloc]
      // initWithRootViewController:expenditureView];

      //    UIViewController *expenditureController =
      //    [self.window.rootViewController.storyboard
      //    instantiateViewControllerWithIdentifier:@"ApprovalView"];
      //    UINavigationController *navVC =
      //    [self.window.rootViewController.storyboard
      //    instantiateViewControllerWithIdentifier:@"navigationController"];
      //    UIViewController *currentVC = self.window.rootViewController;
      //    _window.rootViewController = navVC;
      //    [currentVC presentViewController:navVC animated:NO completion:nil];

      UIStoryboard *storyboard =
          [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];

      ApprovalViewController *appViewController =
          [storyboard instantiateViewControllerWithIdentifier:@"ApprovalView"];
      UINavigationController *navController = [appViewController.storyboard
          instantiateViewControllerWithIdentifier:@"navigationController"];
      navController.view = appViewController.view;
      _window.rootViewController = navController;
      UIViewController *currentVC = self.window.rootViewController;
      [currentVC presentViewController:navController animated:NO completion:nil];

      // [self.window addSubview:self.navVC.view];
      // [self.window setRootViewController:self.navVC];

      // Navigation

      // UINavigationController *navCon = [[UINavigationController alloc] init];
      //[navVC pushViewController:expenditureView animated:NO];

      //[expenditureView.navigationController setNavigationBarHidden:FALSE
      // animated:YES];

      // self.window.rootViewController = expenditureView;

      return YES;
    }
