问题 I have an app with a storyboard. I am using several View Controller with segues to choose from a table view depending on the item selected. I want to have a page view controller in which the pages will be one or more view controller from the storyboard, even repeating them.

Progress of UIPageViewController

阅读更多关于 Progress of UIPageViewController

问题 I would like to receive updates from the uipageviewcontroller during the page scrolling process. I want to know the transitionProgress in %. (This value should update when the user move the finger in order to get to another page). I'm interested in the animation progress from one page to another, not the progress through the total number of pages. What I have found so far: There is a class called UICollectionViewTransitionLayout that have the property corresponding to what I am looking for,

UIPageViewController didFinishAnimating not called if swiped quickly

阅读更多关于 UIPageViewController didFinishAnimating not called if swiped quickly

I have a UIPageViewController that works as expected. I can scroll left and right and the delegate method didFinishAnimating is called when I scroll each direction. However, if I scroll too quickly I end up on a page where didFinishAnimating is not called, though it is called for all previous pages. Does anyone know why this might be happening? I would think that didFinishAnimating would be called on every page transition regardless (e.g., even if the turn was aborted). This bug is still here in 2017.. I tried many alternative ways.. now I gave up the hope that this will be fixed by Apple and

I need to display Arabic (Right To Left) content and couldn't find any method to rotate animation of the page curl found by UIPageViewController because basically Arabic books should be turned from Left to right. Bogdan Onu If you are supporting only portrait mode then you should look at the UIPageViewController delegate method pageViewController:spineLocationForInterfaceOrientation: and return UIPageViewControllerSpineLocationMax . But if you want to support both landscape and portrait then you could keep the default spine location animations but provide the pages in the opposite direction

UIPageViewController crashes when flipped too fast during low memory

阅读更多关于 UIPageViewController crashes when flipped too fast during low memory

问题 I had some memory problems due to Xcode's template for a UIPageViewController caching all the page data, so I changed it to load the pages dynamically, so now when my app receives a low memory warning, it releases the memory for page's not showing, but if the user is flipping through the pages real fast by tapping the edge of the screen, it still crashes. I'm guessing this is because it can't free the memory fast enough when didReceiveMemoryWarning gets called. If the user is flipping slowly,

阅读更多关于 iOS 8 / XCode 6 autolayout constraints applied after view appears

问题 I have a project that was working just fine with XCode 5 and iOS 7, but when I recently downloaded XCode 6, I noticed some weird behavior with autolayout. I have a storyboard with a view that just has a UIImageView and two UILabels. This view gets loaded using a UiPageViewController. The UIImageView is centered horizontally and vertically in the view and there are constraints specifying the distance of the two labels from the image view. When there is a case when the storyboard and autolayout
