Hiding the tabbar and removing the space

Question

Is there a way to hide tabbar and remove that space left (around 50px) ?

I tried

self.tabBarController?.tabBar.hidden = true
self.extendedLayoutIncl

My preferred way to do that is using a wrapping controller. If I want to hide the tab bar, I just increase the height of the tab bar controller, thus effectively the tab bar is moved out of the screen.

With this solution you don't need to hack tab bar frame and you don't depend on navigation controller push animation:

import UIKit

class ViewController: UIViewController {
    let tabController: UITabBarController = {
        let tabController = UITabBarController()
        // setup your tabbar controller here

        return tabController;
    }()

    var tabbarHidden = false {
        didSet {
            var frame = self.view.bounds;

            if (tabbarHidden) {
                frame.size.height += self.tabController.tabBar.bounds.size.height;
            }

            self.tabController.view.frame = frame;
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // add the tab controller as child controller
        addChildViewController(self.tabController)
        self.tabController.view.frame = self.view.bounds
        self.tabController.view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
        self.view.addSubview(self.tabController.view)
        self.tabController.didMoveToParentViewController(self)

        // for debugging
        let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(switchTabbar))
        self.tabController.view.addGestureRecognizer(tapRecognizer)
    }

    override func childViewControllerForStatusBarStyle() -> UIViewController? {
        return self.tabController
    }

    override func childViewControllerForStatusBarHidden() -> UIViewController? {
        return self.tabController
    }

    func switchTabbar() {
        UIView.animateWithDuration(0.3) {
            self.tabbarHidden = !self.tabbarHidden
        }
    }
}
