Question

我在PageViewController中创建了ViewController，您可以看到下一个：

MainViewController（viewDidLoad（））

self.pageViewController = UIPageViewController(transitionStyle: .Scroll, navigationOrientation: .Horizontal, options: nil)
self.pageViewController.dataSource = self
self.pageViewController.delegate = self;
self.pageViewController.view.frame = CGRectMake(0, 100, self.view.frame.size.width, self.view.frame.size.height)
let initialViewController : UIViewController! = viewControllerArray.objectAtIndex(self.currentPageIndex) as! UIViewController
let viewControllers: NSArray? = NSArray(objects: initialViewController)

pageViewController.setViewControllers(viewControllers as? [UIViewController], direction: .Forward, animated:true, completion: nil)

self.addChildViewController(self.pageViewController)
self.view.addSubview(self.pageViewController.view)
self.pageViewController.didMoveToParentViewController(self)
    self.syncScrollView()

一切都很好。此viewController捕获方法

上的事件

func presentationCountForPageViewController(pageViewController: UIPageViewController) -> Int

我的问题是这个pageViewController的其中一个页面里面有其他UIPageViewController，其他的UIViewController是关联的。我创建其他UIPageViewController的方式是：

SecondViewController（viewDidLoad()）

self.pageNoticiaViewcontroller = UIPageViewController(transitionStyle: .Scroll, navigationOrientation: .Vertical, options: nil)
            self.pageNoticiaViewcontroller.didMoveToParentViewController(self);
    self.pageNoticiaViewcontroller.dataSource = self;
    self.pageNoticiaViewcontroller.delegate = self;

    let startVC = self.getControllerAtIndex(0) as InicioIndividualUIViewController;

    let viewControllers = NSArray(object:  startVC);

    self.pageNoticiaViewcontroller.setViewControllers(viewControllers as? [UIViewController], direction: .Forward, animated: true, completion: nil);

    self.pageNoticiaViewcontroller.view.frame = CGRectMake(0, 0, self.view.frame.width, self.view.frame.height - 40);

    self.addChildViewController(self.pageNoticiaViewcontroller);
    self.view.addSubview(self.pageNoticiaViewcontroller.view);

问题是：

第二个PageViewController（pageNoticiaViewController）不会调用方法presentationCountForPageViewController ，但会调用方法presentationCountForPageViewController 父

如何对第二个UIViewController的方法PageViewController进行第二次presentationConuntForPageViewController调用，而不是调用父方法？非常感谢你！

我想你必须尝试这样：

self.pageViewController.view.tag=0 

self.pageNoticiaViewcontroller.view.tag=1

并将条件放在datasource和委托方法中，如

示例：

 func presentationCountForPageViewController(pageViewController: UIPageViewController) -> Int
{  

if pageController.view.tag == 0
{
     return  yourcount // here self.pageViewController count
}
else
  {
     return  yourcount  // here self.pageNoticiaViewcontroller count
  }
}

PageViewController嵌入在其他PageViewController中
