XLPagerTabStrip select what view controller will be shown first

Question

I'm using XLPagerTabStrip to switch among a collection of view controllers. I have three view controllers and I would like that middle view controller is shown by default as first.

I could use

let parentViewController = self.parent! as! ParentViewController
parentViewController.moveToViewControllerAtIndex(1)

inside my first view controller, but that first view controller loads some data from the server and if I switch to another view controller while it is loading data, that first view controller will freeze and it won't load data.

Is there a way to show middle view controller as first by default?

this is issue in XLPagerTabStrip you can using `pod 'XLPagerTabStrip' , :git => 'https://github.com/Dagogatc/XLPagerTabStrip.git', :branch => 'moveToViewController-issue'` — a.masri, Apr 10 '18 at 06:03

jump to the defenition of 'currentIndex' and change it to public from private. then you can select your current controller by this code:

currentIndex = 1

In function:

 override func viewControllers(for pagerTabStripController: 
      PagerTabStripViewController) -> [UIViewController] {
            // This line will help you achieve the requirement
            pagerTabStripController.currentIndex = /* required index */


   }

It will work smoothly after you make currentIndex in PagerTabStripViewController as public.

To prevent loading the first tab, moveToViewControllerAtIndex() must be called before viewDidLoad() is called in your PagerTabStripViewController subclass.

You have to use the following lines:

  override func viewDidAppear(_ animated: Bool) {

        self.moveToViewController(at: 2)
        reloadPagerTabStripView()
        
    }
