ios - UIPageController 与 UIPageControl 一起使用？

Question

我一直在使用 UIPageController 在不同的 Controller 之间导航。现在我想在底部添加这些点，这样用户就可以看到他在哪个 Controller 上。这是通过 UIPageControl 实现的。有没有简单的方法可以将这两者结合起来？

Answer 1

从UIPageViewController.h(iOS6+)的底部~

A page indicator will be visible if both methods are implemented, transition style is 'UIPageViewControllerTransitionStyleScroll', and navigation orientation is 'UIPageViewControllerNavigationOrientationHorizontal'. Both methods are called in response to a 'setViewControllers:...' call, but the presentation index is updated automatically in the case of gesture-driven navigation.

- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController NS_AVAILABLE_IOS(6_0); // The number of items reflected in the page indicator.
- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController NS_AVAILABLE_IOS(6_0); // The selected item reflected in the page indicator.

否则，我认为您需要将 UIPageControl 添加到您的 UIPageViewController 并将它们基本上绑定(bind)在一起以保持它们同步...但是您必须这样做所有的手动绑定(bind)。
