Hide tab bar in IOS swift app

Question

I\'m trying to figure out how to hide the tab bar in my iOS swift app. I don\'t care about any fancy animations or anything. Just something I can put in the ViewDidLoad() fu

Answer 1

To hide the navigationBar and the tabBar I use the next function:

var tabBarHeight : CGFloat!

func fullScreenAction(){
    if navigationController?.isNavigationBarHidden ?? false {
        //Show navigationBar
        navigationController?.setNavigationBarHidden(false, animated: false)

        //Show tabBar
        tabBarController?.tabBar.isHidden = false
        //Update the height of tabBar
        if (!(tabBarController?.tabBar.frame.size.height.isEqual(to: 0))!) {
            tabBarHeight = self.tabBarController?.tabBar.frame.size.height
        }
        tabBarController?.tabBar.frame.size.height   = tabBarHeight
    } else {
        //Hide navigationBar
        navigationController?.setNavigationBarHidden(true, animated: false)

        //Hide tabBar
        tabBarController?.tabBar.isHidden = true
        //Update the height of tabBar
        tabBarHeight = tabBarController?.tabBar.frame.size.height
        tabBarController?.tabBar.frame.size.height   = 0

    }

}

When the screen orientation has changed the height of tabBar change too, so I use the next function to exit of fullscreen to resize the height:

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)
    if navigationController?.isNavigationBarHidden ?? false {
        navigationController?.setNavigationBarHidden(false, animated: false)
        tabBarController?.tabBar.isHidden = false
    }
}

I hope it is useful for you.
