Push View Controller by overriding shouldSelect method in TabbarViewController

I want to push a ViewController when an item in TabBar is selected I have written following code but it is not working

func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {
    if let ind = tabBarController.viewControllers!.index(of:viewController) , bottomBarTabsArray[ind].viewType == BottomBarInfo.VIEWTYPE_ASSISTANT { //
          let tabVC = AppStrings.appStoryBoard.instantiateViewController(withIdentifier: "assitantViewControllerID") as! AssitantViewController
        self.selectedViewController?.navigationController?.pushViewController(tabVC, animated: true)
         return false
     }
    return true
}

how to push ViewController when tabbar item is selected instead of switching to ViewController

Solution

  • Replace

    self.selectedViewController?.navigationController?.pushViewController(tabVC, animated: true)

    with

    (self.selectedViewController as! UINavigationController ).pushViewController(tabVC, animated: true)
