uipageviewcontroller

问题 I'm developing a simple UIPageViewController that has two pages. Each page is loaded from a different ViewController with their specific xib files, named PViewController and TViewController . For PViewController , there are three different views, let's call them A , B , and C . When the application launches, PViewController appears successfully and I can swipe left to see the TViewController , also with no problems. However, when I'm in PViewController and as a response to an event I change

问题 What I have I have a ViewController (TutorialViewController) and a UIPageViewController (TutorialPageViewController). There are also 3 extra views on the storyboard with StoryBoard ID's: GreenViewController BlueViewController RedViewController I have been following this tutorial (Kudos to the author, very well written). On the Green View Controller I have defined a variable: var passedVariable = "" And in the ViewDidLoad I print it out. Here are the two controllers that have the code:

问题 Please forgive me, there are already a ton of questions on how to add a UIBarButtonItem to a NavigationBar programmatically but I just can't seem to get any of the solutions to work in my situation. Here is the layout of a simple test app I have been working with to learn the UIPageViewController. I have the page view controller working nicely with three unique viewControllers. I would now like to set unique rightBarButtonItems for each of the view controllers. I can easily set a common

问题 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

问题 I have 3 types of VC's , 1st Vc, 2nd VC is PageViewController with 3 pages(I added PageController to normal ViewController here), third one is FinalViewController . 1st VC has button when i click it will move to 2nd VC that is PageViewController (It has 3 pages[3 ViewConrollers ] working fine).

问题 I'm working on an iBooks type of app for iOS 5 and have everything working except for the background image. Specifically in landscape mode. Up to this point I've been using: UIImageView *background = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"book.png"]]; [self.view addSubview:background]; [self.view sendSubviewToBack:background]; If I do this on the RootViewController, the spine obviously doesn't show through the page view controller's view and if I use this inside the page

问题 I have a UIPageViewController that handles turning the pages of my "book". However, each book page is a ViewController with a UIScrollView as a subview . The UIScrollView is only able to scroll vertically due to the contentSize . The problem is that while the user scrolls the scrollview vertically, as the scrollview is still scrolling/decelerating the user can not turn the page. A very easy way to see this is to scroll the page and then try to tap the edge of the view. This would normally

问题 I assume that the answer to this question will address issues with Objective-C protocols in general, but this is the first problem of this type that I've come across. I expect for these methods to be used, when implementing UIPageViewControllerDataSourceWithConnections . import UIKit protocol UIPageViewControllerDataSourceWithConnections: UIPageViewControllerDataSource { var connectedViewControllers: [UIViewController] {get} } extension UIPageViewControllerDataSourceWithConnections { func
