问题 I made UIPageViewController with datasource array and it's works correctly. But when swiping to right for forwarding call both of After and Before methods. My codes is here: import UIKit class MainPageViewController: UIPageViewController,UIPageViewControllerDataSource { override func viewDidLoad() { super.viewDidLoad() self.dataSource = self initUPageVC(idx:0,isAnimate:false,direction: UIPageViewControllerNavigationDirection.forward) } func pageViewController(_ pageViewController:

问题 I have two UIViewControllers, A and B, I connect them within a UIPageViewController: Here is how it looks in the Storyboard: I don't know how to pass data to B from A. 回答1: Well assume you have some class (which you should have provided) like: class MyModel { var dataFromFirstController: Any? var dataFromSecondController: Any? var sharedData: Any? } Now you need a subclass of page view controller which is the one that controls the data so override view did load to create a model: var myModel:

问题 I am trying to understand Apple's default template for a Page-based application. That template shows a sort of calendar with one page for each month of the year. When compiling the template without any changes, I noticed something odd. When the app launches, it displays in portrait mode, and when - after flipping through some of the pages (say, to June) - you change the rotation, it reloads in landscape mode showing two pages, BUT STARTING WITH JANUARY. This happens only once, though. On

问题 I try to display photos in UIPageViewController . Firstly I display my photos in a collection view and then tap one photo to enter page view.

问题 I have a controller with two UIViews the first one have 200 of height(constant across all iPhones) and the second one UIViews contain a PageViewController and should get the rest of the height and it does. The problems come when the UITableView get the data, It resize the UIView , with the resize, the UIView now have more height than it should have ( because tableView resized it) and I am not able to scroll to the last object. Example: Height screen = 600 First UIView = 200; Second UIView =

问题 For my project UIPageViewController could be a good choice, so, I started with the template provided by XCode 6.4 starting new project. I used the template: Page-Based Application which has already the basic implementation of UIPageViewController. The opportunity to scroll the pages is working fine, however, I would like to add the navigation bar as well. After reading the articles on that topic I tried to embed DataViewController into NavigationController (Editor>Embed), and then added the
