uipageviewcontroller

Hey I'm using a UIPageViewController to control what page I am on and for scrolling. I know it's possible to show a Page Controller along with it by simply adding the following two functions. - (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController - (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController What I want to know is if it's possible to change the color of the page controller, so the dots are more visible on the background I'm using? I know a regular page controller has the properties: @property(nonatomic

I want to get current index of a pageViewController, I don't know how I get the visible pages index. func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool,previousViewControllers: [UIViewController],transitionCompleted completed: Bool) { // How to get it? } You can use didFinishAnimating, and set tags to viewcontrollers. try this func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) { if (!completed) { return } self

My app keeps crashing, when I set more than one view controller in my app, like below. [self setViewControllers:_images direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL]; My images is an array of view controllers. The app crashes saying the following error. I have no idea where to start. Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'The number of view controllers provided (9) doesn't match the number required (1) for the requested transition As the error says,you are providing more view controllers than needed. You should

When I navigate through UIPageViewController faster than its transition animation I am getting ' Unbalanced calls to begin/end appearance transitions for <MyDataViewController> ' and one of the two views in landscape isn't shown until I try to turn the page. Anybody has an idea to solve this bug? The above answers were right, but I think more elaborate than needed, and cookbook is helpful. So here is what seems to be working for me: In the view controller that sets up and calls the pageViewController, declare: @property (assign) BOOL pageIsAnimating; and in viewDidLoad: pageIsAnimating = NO;

I have a big problem with my UIPageViewController . I want to present content in my app using sections and sub-sections. So, I have created "two" instances of UIPageViewController - horizontal (red) and vertical (blue): Earlier I said I have created "two" instances - it is not quite true - there can be tens of instances, but only 2 are presented at the same time, you know what I mean . Both controllers have transitionStyle set to UIPageViewControllerTransitionStyleScroll . The red UIPageViewController is responsible for horizontal scrolling between sections and blue are responsible for

While switching between Tabs too fast in UIPageViewController, App getting crash in line [UIPageViewController queuingScrollView:didEndManualScroll:toRevealView:direction:animated:didFinish:didComplete:] with errors Assertion failure and Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'No view controller managing visible view.

I want to ask some question about Xcode 4.5. I am creating app with storyboard. This app has UIPageViewController . But if I want to define identifier of UIViewController in IB of storyboard, there is no place for it anymore. Can you please tell me, where can I simple define (using IB) identifier of view controller? It seems that in XCode 4.5 Identifier below Attributes inspector has moved to Storyboard ID below Identy inspector. 来源： https://stackoverflow.com/questions/12471429/uipageviewcontroller-using-storyboard-and-xcode-4-5
