问题 When I programmatically turn the page in a UIPageViewController using a method similar to this answer, the Page Indicators are not updated. Swiping to the next/previous page updates the page indicators as expected. What do I need to do to update the Page Indicators when programmatically turning the page? i.e. How do I set the current "index" after programmatically changing the page so the Page Indicators know which page indicator to show as active? I noticed in the documentation, the

问题 I'd like to show a book on landscape iPhone that would use page curl from UIPageViewController, but I'd like book not to take the whole screen.

问题 In my application I have a RootViewController (UIPageViewController), a FirstController (UIViewController) and a SecondController (UIViewController).

问题 I'm using a UIPageViewController with Navigation set to Horizontal, Transition Style set to Scroll (in InterfaceBuilder), and no spine. Which gives me a lovely UIPageControl integrated.

问题 Regarding to this tutorial by AppCoda about how to implement a app with UIPageViewController I'd like to use a custom page control element on top of the pages instead of at the bottom. When I just put a page control element on top of the single views which will be displayed, the logical result is that the control elements scrolls with the page view away from the screen. How is it possible to put the control element on top of the views so the page views are full screen (like with an image) so

问题 I have a rootViewController which is basically my pageViewController which implements all the page controller protocol functions. I have already successfully implemented the whole pageViewController with a pageControl that correctly shows the current Page number. On the first page contained within the rootViewController, I have a viewController in which there are multiple textFields which have to be filled in with a pickerView. I have also created an inputAccessory toolBar which accompanies

问题 I have 2 tableView s at the moment. One is a basic tableView which shows cells and if selected, it goes into a detailed viewController . I created a new viewController to create a filtered page view. I populate my page view with a plist. I managed to create a filter but don't know how to proceed from here. This is what I have: - (IBAction)ingredientsAddButton:(UIButton *)sender { int j=0; onemsiz.text=ingredientTextField.text; ingredientText=onemsiz.text; NSLog(ingredientText); NSString *path
