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.
