uipageviewcontroller

问题 MY WORK SO FAR: So I have a Tab bar that looks like this: When I click on "Canteen" I want to be directed to a Page View Controller where I can swipe between different pages but stay on the same tab. I have this somewhat working: I have the Storyboard setup like this: As you can see that segue above is coming from the Tab Bar Controller.

问题 I'm using the Page-Based Application template in Xcode 4 to load pages of a PDF and create a UITextView over hidden text boxes so the user can write notes. So far I have it all working, but when I add the UITextView, it's in the wrong place in landscape mode (showing 2 pages). // ModelController.m - (id)init { self = [super init]; if (self) { NSString *pathToPdfDoc = [[NSBundle mainBundle] pathForResource:@"My PDF File" ofType:@"pdf"]; NSURL *pdfUrl = [NSURL fileURLWithPath:pathToPdfDoc];

问题 I have been trying to figure this out for hours, and I must be misunderstanding how UIPageViewController works. I have 5 setup screens (separate view controllers that are loaded into the UIPageViewController ) that I can swipe right + left to see. BUT! I want to be able to programmatically show the next view controller in line after they dismiss an alert on one of those view controllers. And so far, the only solution that I've found that gets close, is this solution here ( https://github.com

问题 I have to implement a UIPageViewController as a subview to my UIViewController. The UIPageViewController has some logic and other ViewControllers inside. My question is how to connect these two pieces of code below.

问题 My architecture of viewcontrollers are: mainViewController(full-screen) | V pageViewController(part-of-screen) | | V V tableViewController1 tableViewController2 Unlike most of existing posts, the UIPageViewController is set to style: UIPageViewControllerTransitionStyleScroll , which means that pageVC.gestureRecognizers is empty, and I can NOT find the tapGuesture to disable. I've searched the site for a whole afternoon, and find NO solution (most answers are related to the pageCurlStyle).

问题 In storyboard I have a UIPageViewController and this is my code class ReservedTimesViewController: UIPageViewController { override func viewDidLoad() { super.viewDidLoad() } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() } } extension ReservedTimesViewController: UIPageViewControllerDataSource { func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? { let controller =

问题 I have UIPageViewController with one of its view controllers being a UITableViewController . Each UITableViewCell can collapse/expand to hide/show a nested table view.

问题 If viewControllerBeforeViewController viewControllerAfterViewController either of the method returns nil the counter part is also called. Is this behaviour expected behaviour ?

问题 I setup UIPageViewController to forward and backward through some view controllers . I have a problem which is when a view controller adds to UIPageViewController the memory usage will increase until the compiler gives me Received memory warning and then app runs too slowly until the app empties the memory and works fine again .
