i'm working with the third party lib XLPagerTabBarStrip. it has delegate

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

Now i'm trying to pass my array that contains the storyboard identifiers names. I'm running for loop to get the name and than pass that to my return statement. When i run the app it shows only last item of array. How can i pass all items of array to the return statement? My code is this,

var child1 = UIViewController()

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

    let viewController = ["LoggedInVC","RegisterationVC"]

    for items in viewController{
        child1 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: items)

    }
    return [child1]
}

When i run the app it only shows vc with identifier RegisterationVC. How can i show both at once?

Your var child1 is of type UIViewController and you override this variable every time your loop is executed.

What you need is an Array of UIViewController

Try this: 

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

    var childs = Array<UIViewController>()

    let viewControllers = ["LoggedInVC","RegisterationVC"]

    for item in viewControllers {
        childs.append(UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: item))
    }

    return childs
}

  • if i have dynamic array , can this be done by this method? @Teetz – raheem Jun 05 '18 at 07:37
  • @raheem What do you concretely mean with dynamic array? (You can edit your question if you want to provide more information) – Teetz Jun 05 '18 at 07:43
  • no i'm just asking that if i had dynamic array than this method could be written? @Teetz – raheem Jun 05 '18 at 07:44
  • just fill the array of identifiers which you need depending on what you want to achieve. – Teetz Jun 05 '18 at 07:46
