UIPageViewController with PageControl
提问by Daniel Kappacher
I'm using a UIPageViewController to display 4 other ViewControllers. So my RootViewController is a PageViewController which displays 4 other ViewControllers I created in my Storyboard with segues to different Views . All works perfect. But is it possible to add an UIPageControl to this PageViewController. Is this possible anyhow?
我正在使用 UIPageViewController 来显示 4 个其他 ViewController。所以我的 RootViewController 是一个 PageViewController，它显示了我在我的 Storyboard 中创建的 4 个其他 ViewControllers 与不同的 Views 。一切都很完美。但是是否可以向这个 PageViewController 添加一个 UIPageControl。这可能吗？
Or has someone an idea how I can achieve a similar result?
或者有人知道我如何获得类似的结果？
Would be great, thanks!

You need to implement these UIPageViewControllerDataSourcemethods:
您需要实现这些UIPageViewControllerDataSource方法：
Swift
迅速
func presentationCount(for pageViewController: UIPageViewController) -> Int { ... }
func presentationIndex(for pageViewController: UIPageViewController) -> Int { ... }
Obj-C
对象-C
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController
- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController
And you'll get a page control showing up at the bottom 36px of your UIPageViewController. Try changing the color of the view to a dark color, if you can't see them.
你会在 UIPageViewController 底部 36px 处看到一个页面控件。如果您看不到它们，请尝试将视图的颜色更改为深色。
