UIPageViewController setViewControllers, UIPageControl not showing right current number
cocoa-touch, ios, uipagecontrol, uipageviewcontroller
Solution
ok, turned out that i misunderstood one delegate method
- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController {
return [(IntroPageViewController *)[pageViewController.viewControllers firstObject] index];
}
Problem
I'am using a UIPageViewController with horizontal scrolling... as long as the user scrolls, the UIPageControl works correctly, problem occurs when jumping programmatically to next or previous page ``` [self.pageViewController setViewControllers:@[[self viewControllerWithIndex:index]] direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:nil]; ``` Than the index of the UIPageControl isn't right (i would provide the index by myself, but cannot access the UIPageViewController's UIPageControl) ``` - (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController { return IntroScreensCount; } - (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController { return 0; } ``` How to get the current dot index of the UIPageControl right, when changing the UIPageViewController page programmatically?
