子视图滚动不能正常工作SWIFT

Question

目标:使视图控制器具有多个页面并且可以通过分段控制器进行交换,页面内容可以垂直滚动

细节:

• 我制作了一个pagviewcontroller并将其作为子视图嵌入到主视图控制器中

  //add pageviewcontroller as subview to viewcontroller
  if let vc = storyboard?.instantiateViewControllerWithIdentifier("ProfileEditController"){
  
      self.addChildViewController(vc)
      self.view.addSubview(vc.view)
  
      EditTabs = vc as! UIPageViewController
      EditTabs.dataSource = self
      EditTabs.delegate = self
  
      //define First page
      EditTabs.setViewControllers([pagesAtIndexPath(0)!], direction:.Forward, animated: true, completion: nil)
      EditTabs.didMoveToParentViewController(self)
  
      //bring segmented view buttons to front of pageViews
      self.view.bringSubviewToFront(self.topTabs)
  }
  

• 我调用了pageViewController函数,我通过恢复标识符添加页面

• 我通过获取pageindex并设置viewcontroller来管理分段视图控制器,如下所示:

  EditTabs.setViewControllers([pagesAtIndexPath(0)!], direction:.Reverse, animated: true, completion: nil)
  

• 在故事板中,子页面内部具有滚动视图以保存内容

• 我测试了子页面滚动视图,通过segue调用它并且工作正常

案件:

• 一切正常只有子页面的滚动视图根本不起作用

如何解决这个问题？我们非常感谢您的指导方针

谢谢,

1. 我用PageViewController创建了一个视图控制器,其中有三个视图控制器,里面有滚动视图.它工作正常.

   import UIKit类ViewController:UIViewController,UIPageViewControllerDataSource {

   var viewControllers : [UIViewController]?
   override func viewDidLoad() {
       super.viewDidLoad()
       CreatePageView()
   }
   
   func CreatePageView() {
   
       SetupViewControllers()
   
       let pageViewController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil)
       pageViewController.dataSource = self
       pageViewController.setViewControllers([(viewControllers?[0])!] , direction: .forward, animated: false, completion: nil)
       pageViewController.view.frame = CGRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height);
       pageViewController.view.frame = CGRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height);
       addChildViewController(pageViewController)
       view.addSubview(pageViewController.view)
       pageViewController.didMove(toParentViewController: self)
       pageViewController.view.backgroundColor = UIColor.blue
   }
   
   func SetupViewControllers() {
       let firstVC = UIViewController()
       firstVC.view.tag = 100
       firstVC.view.backgroundColor = UIColor.red
       AddScrollView(bgView: firstVC.view)
       let secondVC = UIViewController()
       secondVC.view.tag = 101
       secondVC.view.backgroundColor = UIColor.brown
       AddScrollView(bgView: secondVC.view)
       let thirdVC = UIViewController()
       thirdVC.view.tag = 102
       thirdVC.view.backgroundColor = UIColor.purple
       AddScrollView(bgView: thirdVC.view)
   
       viewControllers = [firstVC,secondVC,thirdVC]
   
   }
   
   func AddScrollView(bgView: UIView) {
       let scrollView = UIScrollView()
       scrollView.frame = CGRect.init(x: 10, y: 10, width: bgView.frame.width-20, height: bgView.frame.height-20)
       scrollView.backgroundColor = UIColor.init(red: 0.34, green: 0.45, blue: 0.35, alpha: 0.9)
       bgView.addSubview(scrollView)
       scrollView.contentSize = CGSize.init(width: scrollView.frame.size.width, height: scrollView.frame.size.height+200)
   }
   
   
   func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
       if viewController.view.tag == 101 {
           return viewControllers?[0]
       }
       else if viewController.view.tag == 102{
           return viewControllers?[1]
       }
       else{
           return viewControllers?[2]
       }
   }
   
   public func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
       if viewController.view.tag == 101 {
           return viewControllers?[0]
       }
       else if viewController.view.tag == 102{
           return viewControllers?[1]
       }
       else{
           return viewControllers?[2]
       }
   }
   
   func presentationCount(for pageViewController: UIPageViewController) -> Int {
       return (viewControllers?.count)!
   }
   
   func presentationIndex(for pageViewController: UIPageViewController) -> Int {
       return 0
   }
   

   }
