UIPageViewController delegate method not called

ios, objective-c, uipageviewcontroller, uiviewcontroller, xcode

Solution

Did you assign rootViewController (whichever controller/object you want to receive the delegate calls) to be the delegate/datasource of the UIPageViewController?

pageViewController.delegate = rootViewController;
pageViewController.dataSource = rootViewController;

Problem

In my application I have a RootViewController (UIPageViewController), a FirstController (UIViewController) and a SecondController (UIViewController). The two views inside the two UIViewControllers scroll over the RootViewController. In my RootViewController.h: ``` @interface RootController : UIPageViewController <UIPageViewControllerDataSource, UIPageViewControllerDelegate> ``` But when I scroll between different views delegate methods like: ``` -(void) pageViewController:(UIPageViewController *)pageViewController didFinishAnimating:(BOOL)finished previousViewControllers:(NSArray *)previousViewControllers transitionCompleted:(BOOL)completed ``` are not called. Why? Can someone help me? Thank you in advance.
