uipageviewcontroller

问题 I've been working on a simple test app to learn the ins and outs of the UIPageViewController. I have it working but I'm not convinced my execution is the best way. I hope some of you can point me in the right direction. To get a basic understanding I used this tutorial as a starting point. http://www.appcoda.com/uipageviewcontroller-storyboard-tutorial/ The tutorial creates an app that uses one viewController for each of the pages presented by the UIPageViewController . However I need to

问题 I have a - (void)setViewControllers:(NSArray *)viewControllers direction:(UIPageViewControllerNavigationDirection)direction animated:(BOOL)animated completion:(void (^)(BOOL finished))completion set up in a method. Whenever the method is called it doesn't go to the next page. Instead, it goes to the UIPageViewController storyboard and then crashes. I'm not sure what I'm doing wrong. I am using MSPageViewController for the pageviewcontroller, could that be it? Heres my code: UIViewController

问题 This question already has answers here : how to pass data from UIPageViewController to child ViewController using delegates (2 answers) Closed last year . I need to switch Page View Controller using a button. The initialViewController is the CustomPageViewController. I tried this in the View Controller : class MainViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() } @IBAction func goProfile(_ sender: Any) { CustomPageViewController().goToProfile() } And this

问题 I have created a container for "modul screens" with UIPageViewController. The main problem is a wrong size if set previous screen. On screenshot you can see that are showed 2 screens instead 1. For setting a new screen I use func launchViewControllerC(vc: USBaseVaultStepViewcontroller, step: UIPageViewControllerNavigationDirection, animated: Bool = true) { vc.delegate = self self.pageController.setViewControllers([vc], direction: step, animated: true, completion: nil) } and for the previous

问题 I am having UIPageViewController displaying the Pdf with the help of WKWebView . Now I have to preload the Previous and Next PDF Links for Previous and Next Swipe in order to avoid the loading time for the user. I have tried putting the code when setting up the first ViewController in the PageViewController but when I try to swipe the viewDidLoad is getting called again and then it reloads. I have implemented the following methods : func pageViewController(_ pageViewController:

问题 I’m trying to develop an app that uses 3 different view controllers on the first tab. I have 3 options: 1 - embed the view controllers in an uipageviewcontroller 2 - embed the view controllers in a uiscrollview 3 - use containers controlled by a uisegmentedcontroller - with hidden property true or false… Each of these viewcontrollers are using collectionviews to present photos downloaded asynch from a remote server. Using 3, the photos from all view controllers, loads at the same time, so,

问题 My app works fine in device from xcode. But crashes when run using ipa file. When I checked the console using organizer, the following error has been displayed Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UINibDecoder setScrollEnabled:]: unrecognized selector sent to instance I have used UIPageViewController that displays data in UITextView. Data has been added dynamically using NSOperation to the array , which has been used to display in UITextView. The

问题 I'm using a UIPageViewController to swipe through a series of viewcontrollers. I'd like the background of the parent viewcontroller to smoothly transition between colors when swiping, based on the position of the scroll between views. I was hoping UIPageViewController would have a delegate method similar to scrollViewDidScroll with the position, but it doesn't seem to. Is there an alternate method or similar method to expose the position of the swipe as it occurs/changes? EDIT : Since
