Ho to hide Childe View Controller of ButtonBarPagerTabStripViewController on segment index chnage

Hi I am using ButtonBarPagerTabStripViewController for pager, on segment controller index change

i want hide one child view controller of ButtonBarPagerTabStripViewController.

I used

override public func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] { }

this delegate method to add view controller in ButtonBarPagerTabStripViewController.

How can hide any child view controller of ButtonBarPagerTabStripViewController.

To add your UIViewController to your pagerTabStripController you should have something like :

// MARK: - XLPagerTabStrip required override methods

override public func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {
    return buildViewControllers()
}

// Build the tabs in the tabBar.
func buildViewControllers() -> [UIViewController] {

    // Add custom viewControllers here.

    let aViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "YOUR_IDENTIFIER") as! YOUR_VIEW_CONTROLLER
    let bViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "YOUR_IDENTIFIER") as! YOUR_VIEW_CONTROLLER

    // Other...    

    return [aViewController, bViewController]
}

To hide a specific UIViewController just remove it from the UIViewController array, and call the delegate method again with reloadPagerTabStripView() to reload the tabs
