Swift iOS: how to trigger next page using buttons

Question

I have a QuizViewController which extends UIViewController, UIPageControllerDelegate, and a UIPageView

Answer 1

You can use this function:

func movePageToIndex(pageIndex NSInteger)->() {
    var viewControllers = []
    var direction : UIPageViewControllerNavigationDirection! 
    if (pageIndex < currentIndex) {
        direction = UIPageViewControllerNavigationDirection.Reverse
    } else {
        direction = UIPageViewControllerNavigationDirection.Forward
    }
    viewControllers = @[[self.getItemController(pageIndex)]]

    WEAKSELF weakSelf = self;
    self.pageViewController.setViewControllers:viewControllers direction:direction animated:false completion:nil];
}
