推到另一选项卡的视图控制器

当用户在某个小区（视图）点击一个按钮我要推到另一选项卡的视图控制器推到另一选项卡的视图控制器

tabbarController
---导航控制器---- VC甲
---导航控制器---- VC乙
---导航控制器---- VCç---- VC d

像从视图控制器A至viewcontr奥勒d

我试图赛格瑞

self.window?.visibleViewController?.performSegue(withIdentifier:"homeSegueDetailStatement", sender: self)

的工作，但没有导航栏....

我试图创建一个导航控制器和现在，崩溃...

if let visibleViewCtrl = UIApplication.shared.keyWindow?.visibleViewController { 

      let nav = UINavigationController(rootViewController: visibleViewCtrl) 
      let b = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "PendingStatementVC") as! PendingStatementViewController 
     nav.pushViewController(b, animated:false) 
      visibleViewCtrl.present(nav, animated:true, completion:nil) 
     }

请帮我

编辑---

实际上我想更改选项卡和导航到第二个视图控制器。我呼吁来自collectionCell本功能，这就是为什么我必须GE当前视图 - 控制

编辑--- 我找到了我想要

DispatchQueue.global().async { 
     DispatchQueue.main.async { 
      self.tabBarController?.selectedIndex = 2 
       if let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "DetailStatementVC") as? DetailStatementViewController { 

       if let navigator = self.tabBarController?.viewControllers?[2] as? UINavigationController { 
        navigator.pushViewController(controller, animated: true) 
       } 
      } 
     } 
    }

如果你推的ViewController那么为什么你再presentingviewcontroller –

需要推从appdelegate或Viewcontroller？ – KKRocks

你能告诉我们你的故事板场景吗？ –

尝试是这样的：

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil) 
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "mainView") as! MainViewController 
self.present(nextViewController, animated:true, completion:nil)

像这样尝试

let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil) 
let MainViewControllerObj : MainViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "MainViewController") as! MainViewController 
let navigationControllerObj:UINavigationController = UINavigationController.init(rootViewController: MainViewControllerObj) 
self.present(navigationControllerObj, animated:true, completion:nil)

使用代码下面，你从VC-A到VC-d去，那么你可以去从VC-d回到VC-C

let dViewController = self.storyboard?.instantiateViewController(withIdentifier: "DViewController") as! DViewController 
let thirdTabNavController = self.tabBarController?.viewControllers?[2] as! UINavigationController 
thirdTabNavController.pushViewController(dViewController, animated: false) 
self.tabBarController?.selectedIndex = 2

Try below code: 

let mainStoryBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil) 
let nextViewController = mainStoryBoard.instantiateViewController(withIdentifier: "DcontrollerIdentifier") as! DViewController 
self.navigationController?.pushViewController(nextViewController, animated: true)
