APLPageViewControllerDataSource provides an index based API on top of the viewControllerBeforeViewController and viewControllerAfterViewController API of UIPageViewController.

Installation

Usage

Import header file:

#import "APLPageViewControllerDataSource.h"

Declare a dataSource property:

@property (nonatomic) APLPageViewControllerDataSource *dataSource;

Create a APLPageViewControllerDataSource instance and configure it:

    APLPageViewControllerDataSource *pageViewControllerDataSource = [APLPageViewControllerDataSource new];
    pageViewControllerDataSource.delegate = self;
    pageViewControllerDataSource.pageViewController = pageViewController;
    pageViewControllerDataSource.objects = @[] // your data objects
    self.dataSource = pageViewControllerDataSource;

Declare the protocol methods required to configure the view controller

- (UIViewController*)pageViewControllerDataSource:(APLPageViewControllerDataSource *)dataSource contentViewControllerForIndex:(NSUInteger)index {
    APLContentViewController *detailViewController = [APLContentViewController instantiateFromStoryboard]; // use your own content view controller class
    detailViewController.item = dataSource.objects[index]; // configure your view controller
    return detailViewController;
}

- (NSUInteger)pageViewControllerDataSource:(APLPageViewControllerDataSource *)dataSource indexForContentViewController:(UIViewController *)viewController {
    APLContentViewController *detailViewController = (APLContentViewController*)viewController;
    return [dataSource.objects indexOfObject:detailViewController.item];
}

When you retrieve new data, update your dataSource like this:

self.dataSource.objects = newObjects;
