应用翻转动画到UIPageViewController iOS Xamarin

Question

我想要一本像我的应用程序感觉的书。为此，我有一个UIPageViewController滚动浏览多个页面。一切正常。目前，UIPageViewController的Transition类型是Page curl，但是我想实现更像是一个翻页的东西（就像翻页一样）。

我已经实现了以下内容： -

public new UIViewController GetNextViewController(UIPageViewController pageViewController, UIViewController referenceViewController) 
    { 
    var page = referenceViewController as IpadNewController; 
    var index = page.pageIndex; 
    index ++; 
    if(index == numberOfPages) 
    { 
    return null; 
    } 
    else{ 
    return ViewControllerAtIndex (index); 
    } 

    } 

    public new UIViewController GetPreviousViewController(UIPageViewController pageViewController, UIViewController referenceViewController) 
    { 

    var page = referenceViewController as IpadNewController; 
    var index = page.pageIndex; 
    if(index == 0) 
    { 
    return null; 

    }else{ 
    index --; 
    return ViewControllerAtIndex (index); 
    } 


    } 

编辑

private void LoadData(List<Models.NewsModel> viewPages) 
     { 
     if (viewPages != null) 
     { 
     if (viewPages.Count % 5 == 0) 
     { 
     numberOfPages = viewPages.Count/5; 

     } 
     else 
     { 
     numberOfPages = viewPages.Count/5 + 1; 

     } 
     } 
     this.DataSource = this; 
     var startingViewController = this.ViewControllerAtIndex(0); 
     var viewControllers = new UIViewController[] { startingViewController }; 
     if (startingViewController != null) 
     { 
     this.SetViewControllers(viewControllers, UIPageViewControllerNavigationDirection.Forward, false, null); 
     } 
     this.View.Frame = View.Bounds; 

     } 
private IpadNewController ViewControllerAtIndex(int index) 
     { 
     if (numberOfPages == 0 || index >numberOfPages) 
     { 
     return null; 
     } 
     else 
     { 
     newIpadController = (IpadNewController)this.Storyboard.InstantiateViewController("iPadNew_VC"); 

     newIpadController.pageIndex = index; 

     } 
     return newIpadController; 
     } 

有没有一种方法，我可以改变过渡动画翻转而不是卷曲，而无需使用任何外部库？

在UIPageViewController水平，你只需要而不是使用UIPageViewController的一个UIViewController

PageCurl和Scroll转换，您可以实现自己的视图容器，并使用TransitioningDelegate定义动画为您的系列UIViewController，并将其应用到您的UIViewController各自的UIViewController.TransitioningDelegate财产。

Xamairn有一个名为LookInside的示例，该示例使用实现自定义转换的自定义预览控制器。
