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

Swift 3.

self.tabBarController?.tabBar.isHidden = true

Answer 2

Before push set controller.hidesBottomBarWhenPushed = true

let objCreateEventVC = CreateEventVC()
objCreateEventVC.hidesBottomBarWhenPushed = true
self.navigationController?.pushViewController(objCreateEventVC, animated: false)

Answer 3

You can also set it in extension (use Dharmesh Kheni answer)

extension UITabBar {
func tabsVisiblty(_ isVisiblty: Bool = true){
    if isVisiblty {
        self.isHidden = false
        self.layer.zPosition = 0
    } else {
        self.isHidden = true
        self.layer.zPosition = -1
    }
}

Answer 4

You can simply use this in your ViewDidLoad() method.

self.tabBarController?.tabBar.hidden = true

For Swift 3.0, 4.0, 5.0:

self.tabBarController?.tabBar.isHidden = true

Or you can change z position of tab bar this way:

self.tabBarController?.tabBar.layer.zPosition = -1

and if you want to show it again then:

self.tabBarController?.tabBar.layer.zPosition = 0

Answer 5

No need to set tabBar's isHidden property.

Simply, Go to ViewController (in StoryBoard) -> Attribute inspector -> Under 'View Controller' section select 'Hide Bottom Bar on Push' checkbox. This works like a charm.

If you go the 'isHidden' way you need to do a lot of handling, i.e. to make it appear again when you go back and also to remove the bottom empty space after hiding tabBar.

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.
