如何从嵌入在导航控制器中的简单视图控制器调用标签栏视图控制器？

Question

How can I call TabbarViewControllers connected viewController from simple UIViewController where simple UIViewController is embedded in UINavigationController . I want same Push and Pop effect which UINavigationController provide when moving one to other viewController. After digging in google I find out that pushing tab bar view controller inside navigation stack is not a good way to structure app. I tried creating custom transaction animation but it's not same like UINavigation transaction effect. Please give some suggestion or solution. Thanks!!

Answer 1

You can directly set UITabbarController to window's rootViewController.

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
_tabObj = (TabbarViewController*) [storyboard instantiateViewControllerWithIdentifier:@"TabbarViewController"];
self.window.rootViewController = _tabObj;

Check above code.

Answer 2

as Nirmalsinh 's answer, you could set view controller that conform UITabBarControllerDelegate as your self.window.rootViewController , then should have UITabBarController inside it.

var tabBarController: UITabBarController

then you can each of tab's navigation and view controller

let firstViewController = FirstViewController()
let firstNavigationController = UINavigationController(rootViewController: firstViewController)
// other setter

tabBarController.viewControllers = [
    firstNavigationController
]

then inside FirstViewController , you can call

let secondViewController = SecondViewController()
navigationController?.pushViewController(SecondViewController, animated: true)
