uipagecontrol

问题 I would like to use UIPageControl to navigate between different view controllers. I have 2 view controllers and another main view controller contains the UIPageControl . The 2 view controllers to be navigated between have been added as children to the main view controller. When I currently start the application, I see a blank screen. I used pageControl.currentPage = 0 but I am unable to understand why I am unable to see the views. Note that I do not want to use UIScrollView in my application.

问题 I am using UIPageControl as indicator between different page (view controllers) of my application. In each of the view controllers, I need to have a different button on the left corner on the UIPageControl. If I place a UIButton at that position on each of the view controllers, I see it on the UIPageControl but the buttons do not respond to the touch event. Is there something I am missing? Or is there an alternative to do this? Thanks. 回答1: I guess the page control and the view controller

I would like to send data to the second view controller and also change the page. I would like to know how it is done. 回答1: You would need to have all of the view controllers created (born at least the first 2) rather than loading purely on demand (scroll). Add a property to the first controller which holds a reference to the

问题 For the application I am working on I need a scrollview with paging along with a number of views (in this case tableviews). Setting this up (using Apple's PageControl example) is easy enough and I have no problem making it work in regards to scrolling and snapping between pages. I want the tableviews to be almost like thumbnail representations of the tableviews in the scrollview. Once you click one it opens or zooms in to let the tableview cover the entire screen. Again, setting this up is

问题 In my app I have UIView that flow through the use of a horizontal scrollView. To scroll the view I used the classimo method [self addChildViewController: [self.storyboard instantiateViewControllerWithIdentifier: @ "name Storyboard ID"]]; Each UIView is followed through the use of UIPageControl classic, but I do not like it and so I wanted to create something like this (see photo) as you can see from the images above application there is a menu with a triangle pointing down, Indicating the

问题 Anyone have an idea how to create a vertical UIPageControl? I have a UIScrollView with pagination enabled and I would like to have the UIPageControl sit on the side and appear vertically instead of horizontally.
