The collection context provides limited access to the collection related information that section controllers need for things like sizing, dequeing cells, insterting/deleting/reloading, etc.

@protocol IGListScrollDelegate <NSObject>

Implement this protocol in order to be used within the IGListKit data infrastructure and be registered for use in an IGListAdapter. An IGListSectionType conforming object represents a single instance of an object in a collection of objects.
The infrastructure uses each IGListSectionType conforming object as a
view model
to populate and control cells as part of a section in a UICollectionView feed. IGListSectionType objects should be architected without knowledge ofglobal
state of the feed they are contained in.Index paths are used as a convenience for communicating the section index to each section object without allowing each section to mutate its own position within a feed. The row of an index path can be directly mapped to a cell within an IGListSectionType conforming object.

@protocol IGListSectionType <NSObject>
Swift
protocol IGListSectionType
-
A delegate that can receive selection events on an IGListSingleSectionController.

Objective-C
@protocol IGListSingleSectionControllerDelegate <NSObject>
Swift
protocol IGListSingleSectionControllerDelegate
-
Implement the methods of this protocol to provide information about a list’s supplementary views. This data is used in IGListAdapter which then configures and maintains a UICollectionView. The supplementary API reflects that in UICollectionView, UICollectionViewLayout, and UICollectionViewDataSource.

Objective-C
@protocol IGListSupplementaryViewSource <NSObject>
Swift
protocol IGListSupplementaryViewSource
-
Implement this protocol in order to handle both section and row based update events. Implementation should forward or coalesce these events to a backing store or collection.

Objective-C
@protocol IGListUpdatingDelegate
Swift
protocol IGListUpdatingDelegate
-
Implement this protocol to receive working range events for a list.
The working range is a range near the viewport in which you can begin preparing content for display. For example, you could begin decoding images, or warming text caches.
