I trying to use UIPageViewController to move between controllers. Everything is working fine, but the only issue is that I am changing the transition style in the storyboard from page-curl to scroll. but it is not working. When I run the app and move between controllers, the animation is page-curl !!!
my code is simple, you can check it:
override func viewDidLoad() {
super.viewDidLoad()
let firstViewController = orderedViewControllers[1]
setViewControllers([firstViewController],
direction: .forward,
animated: false,
completion: nil)
self.delegate = self
self.dataSource = self
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
guard let viewControllerIndex = orderedViewControllers.index(of: viewController) else {
return nil
}
let previousIndex = viewControllerIndex - 1
// User is on the first view controller and swiped left to loop to
// the last view controller.
guard previousIndex >= 0 else {
return nil
}
guard orderedViewControllers.count > previousIndex else {
return nil
}
return orderedViewControllers[previousIndex]
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
guard let viewControllerIndex = orderedViewControllers.index(of: viewController) else {
return nil
}
let nextIndex = viewControllerIndex + 1
let orderedViewControllersCount = orderedViewControllers.count
// User is on the last view controller and swiped right to loop to
// the first view controller.
guard orderedViewControllersCount != nextIndex else {
return nil
}
guard orderedViewControllersCount > nextIndex else {
return nil
}
return orderedViewControllers[nextIndex]
}
```
