Swift - Reload UIPageViewController with new information in viewDidAppear

Question

How to reload UIPageViewController in viewDidAppear?

There, I refresh information from CoreData and I want to updated values when the view appears.

I tried with function reloadInputViews(), but unsuccessfully only when you start to open pages then the information is updated.

is your "UIPageViewController" an "IBOutlet" in your view controller? Is your "UIPageViewController" subclassed? – Animality

You need to use the setViewControllers:direction:animated:completion: function to load the view controllers for the page(s) you want to reload. – Touraine

If you want to reload the ViewControllers inside the UIPageViewController, just re-set them with:

pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool)

if you are going to update your viewControllers from inside a viewController, you have to call it this way:

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
    let viewControllers: [UIViewControllers] = [UIViewController()]
    if let pageViewController = parentViewController as? UIPageViewController {
        pageViewController.setViewControllers(viewControllers, direction: .Forward, animated: true, completion: nil)
    }
}

override func viewDidAppear(animated: Bool) { super.viewDidAppear(animated) self.setViewControllers(pageViewController, direction: .Forward, animated: true, completion: {}) } prints an error ViewController does not have a member named setViewControllers – Lawannalawbreaker

this if never executes – Lawannalawbreaker
