Safe Area bottom layout issue with interactivePopGesture

Question

we have used default tabbarcontroller. Tabbar rootViewController display tabbar and other viewcontroller hidden tabbar.The bottom layout of safearea not update hight when we use interactivePopGesture. All other case its working fine

    override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    if navigationController?.viewControllers[0] == self {
        tabBarController?.tabBar.isHidden = false

    } else {
        tabBarController?.tabBar.isHidden = true

    }
}

You need to set the interactivePopGesture Delegate and handle hiding the tabbar. — Sachin Vas, Mar 11 '19 at 07:43

// i was solved this issue like that in appdelegate when iam check user already login then i will remove removeGestureRecognizer from view
 let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
            let loginPageView = mainStoryboard.instantiateViewController(withIdentifier: "CustomTabVCID") as! CustomTabVC
            let rootViewController = self.window!.rootViewController as! UINavigationController
            rootViewController.view.removeGestureRecognizer(rootViewController.interactivePopGestureRecognizer!)
            rootViewController.pushViewController(loginPageView, animated: true)

// for bottom bar
    // Use this [![enter image description here][1]][1]
    // add this line when you navigate to a ViewController hidesBottomBarWhenPushed
    let vc = storyboard.instantiateViewController(withIdentifier: VC_IDENTIFIER) as! YourViewController
        vc.hidesBottomBarWhenPushed = true
     navigationController?.pushViewController(vc, animated: true)

    // hope its work for you

    or try with Main StoryBoard!

why not remove popGesture on your View Controller ? – Sukh Mar 11 '19 at 13:08
PopGesture removing is not a proper solution. – ishwar lal janwa Mar 11 '19 at 13:27

Yes its working, When we need to display tabbar then we need to disable Hide Bottom bar on Push and rest of other viewcontroller we need to set enable Hide Bottom bar on Push. Thanks – ishwar lal janwa Mar 12 '19 at 06:50
