uipageviewcontroller

I have a page view controller in my iPhone app. The view is defined using the Interface Builder and a class to manage it. This class extends UIPageViewController <UIPageViewControllerDataSource,UIPageViewControllerDelegate> I used the following functions for page indicator. -(NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController {} -(NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController {} However, the number of pages in my application increased and the page indicator goes out of my current view (the starting and the

Here i have two classes. How do I make JournalPage call JournalEntryController didSubmit method. protocol JournalPageDelegate { func didSubmit(for commentText: String) } class JournalPage: UIViewController, UITextViewDelegate { var delegate: JournalPageDelegate? fileprivate let textView: UITextView = { let textView = UITextView() let attributedText = NSMutableAttributedString(string: "Enter Text Here.", attributes: [NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: 18)]) textView.textColor = UIColor.black textView.backgroundColor = UIColor.white textView.becomeFirstResponder() textView

I followed the tutorial over @ http://www.appcoda.com/uipageviewcontroller-storyboard-tutorial/ to implement a UIPageViewController. I need to make the transition between view controllers to fade in/out when the user scrolls between them. An example of an app that does this is over here https://itunes.apple.com/us/app/tapiture/id645402534?mt=8 Use the delegate pageViewController:willTransitionToViewControllers: .

I thought it will be good to refresh this topic across SO community since it remains unsolved for some reason I've browsed through many threads here, but most answers are outdated or marked as unreliable(The result depends on if user did a full swipe or just half swiped etc) I've visited this thread, but it doesn't provide any explicitly correct answer. I've tried: 1) Keeping track of

In my app I have a RootPageViewController which contains the UIPageViewController and one or more DetailPageViewController with a UITableView as a childview. DetailPageViewController / RootPageViewController - DetailPageViewController \ DetailPageViewController On top of every DetailPageViewController is a little space where it should be possible to swipe and get to the next DetailPageViewController. ------------------- | | | | -> UIPageViewController should respond to pan's | | |-------------------| -------------------------------------------- | CellContent | |-------------------| |

The goal is to create a UIPageViewController that can only navigate forward. I am using a data source to provide the content for the UIPageViewController. The direction is set to UIPageViewControllerNavigationDirectionForward , the transition style is UIPageViewControllerTransitionStyleScroll . The implementation of - (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController { // returns the next view controller } returns the next view controller, while the following should ensure navigating backwards
