Hiding the Tabbar and Removing the Space

Hiding the tabbar and removing the space

If you're still seeing a black stripe under your hidden tab bar, have you tried to select Extend Edges Under Opaque Bars here?

Make also sure that Under Bottom Bars is still selected. Hope it helps!

How to remove empty space behind the `PTCardTabBar` when it is hidden?

As I said in my comment, you'll need to do some digging into that PTCardTabBarController code.

I spent a few minutes playing with it, and this might help you out... tried to make as few changes as possible, so I only edited PTCardTabBarController.swift.

So...

• added Two constraint vars: customTabBar Bottom Anchor and customTabBar Top Anchor
• the bottom anchor constrains the Bottom of the custom tab bar to the top of the "small view". This will be active when the tab bar is showing.
• the top anchor constrains the Top of the custom tab bar to the Bottom of the view. This will be active when the tab bar is hidden.
• added a showTabBar() func to show/hide the custom tab bar with optional animation.
• in viewDidLayoutSubviews() set the frame of the hidden "built-in" tab bar to below the bottom of the view.

Now I can, for example, do this:

if let ptcTBC = tabBarController as? PTCardTabBarController {
    ptcTBC.showTabBar(false, animated: true)
}
performSegue(withIdentifier: mySegueID, sender: indexPath)

and then on return:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    if let ptcTBC = tabBarController as? PTCardTabBarController {
        ptcTBC.showTabBar(true, animated: true)
    }
}

I forked that PTCardTabBar repo and added a complete example here: https://github.com/DonMag/PTCardTabBar-1

White space in place of a hidden tab bar

Thank you for all
I have found the best solution to my problem .

MyImageViewController.hidesBottomBarWhenPushed = YES ;
[self.navigationController pushViewController:MyImageViewController animated:YES];

It gave me the response I wanted .
Thank you for your share

Hiding Tabbar still occupy Space?

You can try this:

yourInnerViewController.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:yourInnerViewController animated:YES];

Hide tab bar in IOS swift app

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

Removing Tabbar from tabbedpage leaves blank space. How to remove it?

Adding following function to the renderer removed blank space from TabbedPage.

public override void ViewDidLayoutSubviews()
{
    base.ViewDidLayoutSubviews();

    TabBar.Hidden = true;

    var page = View.Subviews[0];
    var tabbar = View.Subviews[1];

    tabbar.Bounds = CGRect.Empty;
    page.Bounds = UIScreen.MainScreen.Bounds;
}
