JKPagingViewController

by Jonas Keisel

Getting started

This project includes a demo application (both for iPhone and iPad, though there is no difference), showing hot to create and configure an example JKPagingViewController.

Creating the User Interface

1. Drag a UIView from the Utilities-Panel onto the Storyboard
2. Wire it up with an IBOutlet in your UIViewController
3. Optional: If you want a UIPageControl somewhere special, put one on your Storyboard and wire it up as well

Setting up a JKPagingViewController

JKPagingViewController *pagingViewController = [[JKPagingViewController alloc]  initWithView:self.pagingView andPageControl:self.pageControl];
pagingViewController.dataSource = self;

The pageControl parameter may be nil. If this is the case, a UIPageControl is added automatically at the bottom of the view. To suppress a UIPageControlbeing shown automatically, just add this line:

pagingViewController.usePageControl = NO;

Providing data for the JKPagingViewController

The JKPagingViewController receives its data via a data-source-protocol.

@interface MyViewController : NSObject <JKPagingViewControllerDataSource>

These Methods are required:

- (NSUInteger)numberOfPagesInPagingViewController:(JKPagingViewController *)pagingViewController;
- (UIViewController *)pagingViewController:(JKPagingViewController *)pagingViewController viewControllerAtIndex:(NSUInteger)index;

Getting informed as soon as the page is changed

For this to happen, you have to set a delegate:

pagingViewController.delegate = self;

Of course your UIViewController (or whichever class you choose to be the delegate) has to conform to a protocol:

@interface MyViewController : NSObject <JKPagingViewControllerDataSource, JKPagingViewControllerDelegate>

These optional methods are called by the JKPagingViewController

- (void)pagingController:(JKPagingViewController *)sender willChangeFromPage:(NSUInteger)from toPage:(NSUInteger)to;

JKPagingViewController is released under its own license (which is included with the source code).
