IGListSectionController

@interface IGListSectionController : NSObject

The base class for section controllers used in the list infra. This class is meant to be subclassed.

  • The view controller housing the adapter that created this section controller.

    @discussion Use this view controller to push, pop, present, or do other custom transitions. It is considered very bad practice to cast this to a known view controller and call methods on it other than for navigations and transitions.

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable) UIViewController *viewController;

  • A context object for interacting with the collection i.e. accessing the collection size, dequeing cells, reloading/inserting/deleting, etc.

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable) id<IGListCollectionContext>
    collectionContext;

    Swift

    weak var collectionContext: AnyObject? { get }

  • The margins used to lay out content in the section controller.
