uipageviewcontroller next button swift
//Very simple solution is here //To change page (UIViewController) from a UIViewController, first get the instance of Parent ViewController (which will be UIPageViewController) and then set its current ViewController //In my case I have a UIPageViewController named "UserDetailsPVC" and it contains 4 pages (UIViewControllers) which are as follows PageOneVC:UIViewController PageTwoVC:UIViewController PageThreeVC:UIViewController PageFourVC:UIViewController //In the UIPageViewController lets define an array of pages var pages:[UIViewController] = [ UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "PageOneVC"), UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "PageTwoVC"), UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "PageThreeVC"), UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "PageFourVC") ] //Now to change page of UIPageViewController from any of the UIViewController // get parent view controller let parentVC = self.parent as! UserDetailsPVC // change page of PageViewController parentVC.setViewControllers([parentVC.pages[1]], direction: .forward, animated: true, completion: nil)
