如何添加第二个UIPageViewController [英] How to add a second UIPageViewController

问题描述

我正在使用UIPageViewController创建一个项目来实现翻页效果。我正在使用故事板，我认为很棒，设置UIPageViewController。如何添加第二个UIPageViewController并将其挂钩？我已经发布了一些截图来展示我到目前为止所做的事情。

I'm creating a project using UIPageViewController for the page turning effect. I'm using storyboard, which I think is great, to setup the UIPageViewController. How do I add a second UIPageViewController and hook it up? I have posted some screenshots to show what I've done so far.

推荐答案

我认为您要做的是实现页面视图控制器数据源代理：

I think what you are looking to do is to implement the page view controller data source delegates:

- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController

这些当从页面视图控制器请求时，两个函数返回下一个和上一个视图控制器。

These two functions return the next and previous view controllers when they are requested from the page view controller.

如果您创建一个新的基于页面的应用程序项目，您可以在ModelController中完成此操作，该模型是示例pageViewController的数据源。

If you make a new "Page-Based Application" project, you can follow how this done in the ModelController which is the data source for the example pageViewController.
