Changing UIPageViewController's page programmatically doesn't update the UIPageControl

Question

In my custom UIPageViewController class:

- (id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self) {
           


        

Answer 1

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.

The answer above, given by aansul, works.

Note : Don't forget to set the pageViewController's Transition style to Scroll instead of Page Curl. Otherwise it won't work.
