SIBGridModeAppearance Protocol Reference

Conforms to	NSObject
Declared in	SIBGridModeAppearance.h

Overview

Since SCItemGridBrowser overrides the UICollectionViewDelegate and UICollectionViewDataSource protocols, there should be some way to configure cells appearance.

Override methods of this protocol to forward your values to the UICollectionView and customize its appearance.

Tasks

– itemsBrowser:didHighlightCell:forItem:atIndexPath:
Tells the delegate that the item at the specified index path was highlighted. Overloading this method you may do some changes to the cell so that the user gets visual feedback while tapping on it.
– itemsBrowser:didUnhighlightCell:forItem:atIndexPath:
Tells the delegate that the item at the specified index path was unhighlighted. Overloading this method you may revert the cell’s appearance to the initial state so that the user gets visual feedback while finishing tapping on it.
– itemsBrowser:transitionLayoutForOldLayout:newLayout:
Asks for the custom transition layout to use when moving between the specified layouts.
See [UICollectionView collectionView:transitionLayoutForOldLayout:newLayout:] documentation for details.

Instance Methods

itemsBrowser:didHighlightCell:forItem:atIndexPath:

Parameters
