UIPageViewController with only one content view controller

问题

I have an app with webView and some JS-tricks to present text. Paging is implemented in JS and I just pass events from gestures to JS functions. But what I miss is animation. Know user just see another portion of text when he turns the page with swipe. So I decided to use UIPageViewController. I need a one controller to be shown and it will change it state during animation of turning. So the same one will be returned every time in

-(UIViewController*) pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController  

and

- (UIViewController*) pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController

Now I have an error doing this.

Finally, the question - can only one controller be used for proper animation in pageViewController?

回答1:

You can use UIView's transitionWithView: method to animate content changes and add a curl animation just like this:

    [UIView transitionWithView:self.view
                      duration:0.5
                       options:UIViewAnimationOptionTransitionCurlUp
                    animations:^{
                        // change your content here
                    }
                    completion:^(BOOL finished) {
                        // optional completion block
                    }];

It seems to me you actually want to use a simple UIScrollView with pagingEnabled. Maybe you confused UIPageViewController with UIPageControl?
