UIPageController in conjuction with UIPageControl?

Question

I have been using UIPageController to navigate between different controllers. Now I would like to add that dots at the bottom, so user can see on which controller he is at. That is achieved via UIPageControl. Is there easy way to combine those two?

Answer 1

From the bottom of UIPageViewController.h (iOS6+) ~

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.

Otherwise, I think you need to add a UIPageControl to your UIPageViewController and basically tie them together to keep them in sync...but then you do have to do all the tying manually.
