super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
pageViewController.pageViewDelegate =selfself.addChildViewController(pageViewController)self.view.addSubview(pageViewController.view)
pageViewController.didMove(toParentViewController:self)}overridefunc viewDidLayoutSubviews(){
pageViewController.view.frame =self.view.bounds
}

Implement ICPageViewControllerDelegate

func numberOfItems(in pageViewController:ICPageViewController)->Int{return10}func pageViewController(_ pageViewController:ICPageViewController, viewControllerForItemAt index:Int)->UIViewController{letviewController=self.storyboard?.instantiateViewController(withIdentifier:"demoViewController")as?SubViewController
viewController?.label ="sub viewcontroller \(index)"switch index {case0:
viewController?.view.backgroundColor =.blue
case1:
viewController?.view.backgroundColor =.red
