Swift/iOS8: Why are Page Control indicators not showing?

Question

I am implementing a straightforward gallery view controller where the app displays a small range of full-screen images that the user can scroll through. I\'m using UIPageViewCon

Answer 1

Taken from here :

In order to show UIPageControl, you need to implement two optional datasource methods. Just return the whole number of pages for presentationCountForPageViewController and the initially selected index for presentationIndexForPageViewController

func presentationCountForPageViewController(pageViewController: UIPageViewController) -> Int {
    return pageContent.count
}

func presentationIndexForPageViewController(pageViewController: UIPageViewController) -> Int {
    return 0
}
