Description copied from class: UIViewController

The designated initializer. If you subclass UIViewController, you must call the super implementation of this method, even if you aren't using a NIB. (As a convenience, the default init method will do this for you, and specify nil for both of this methods arguments.) In the specified NIB, the File's Owner proxy should have its class set to your view controller subclass, with the view outlet connected to the main view. If you invoke this method with a nil nib name, then this class' -loadView method will attempt to load a NIB whose name is the same as your view controller's class. If no such NIB in fact exists then you must either call -setView: before -view is invoked, or override the -loadView method to set up your views programatically.

Description copied from interface: UICollectionViewDelegate

Allows a two-finger pan gesture to automatically enable allowsMultipleSelection and start selecting multiple cells. After a multi-select gesture is recognized, this method will be called before allowsMultipleSelection is automatically set to YES to allow the user to select multiple contiguous items using a two-finger pan gesture across the constrained scroll direction. If the collection view has no constrained scroll direction (i.e., the collection view scrolls both horizontally and vertically), then this method will not be called and the multi-select gesture will be disabled. If this method is not implemented, the default is NO. API-Since: 13.0

Description copied from interface: UICollectionViewDelegate

Called when a context menu is invoked from this collection view. The @c indexPaths array may contain 0-many items: - An empty array indicates that the menu was invoked in the space between cells (or any location that does not map to an item index path). - An array with multiple index paths indicates that the menu was invoked on an item within a multiple selection. API-Since: 16.0

Specified by:

collectionViewContextMenuConfigurationForItemsAtIndexPathsPoint in interface UICollectionViewDelegate

Parameters:

collectionView - The @c UICollectionView.

indexPaths - An array of index paths on which the menu acts.

point - Touch location in the collection view's coordinate space.

Returns:

A @c UIContextMenuConfiguration describing the menu to be presented. Return nil to prevent the interaction from beginning. Returning an empty configuration causes the interaction to begin then fail with a cancellation effect. You might use this to indicate to users that it's possible for a menu to be presented from this element, but that there are no actions to present at this particular time.

Description copied from interface: UICollectionViewDelegate

Called when the primary action should be performed for the item at the given indexPath. Primary actions allow you to distinguish between a change of selection (which can be based on focus changes or other indirect selection changes) and distinct user actions. Primary actions are performed when the user selects a cell without extending an existing selection. This is called after @c shouldSelectItem and @c didSelectItem , regardless of whether the cell's selection state was allowed to change. As an example, use @c didSelectItemAtIndexPath for updating state in the current view controller (i.e. buttons, title, etc) and use the primary action for navigation or showing another split view column.

Specified by:

collectionViewPerformPrimaryActionForItemAtIndexPath in interface UICollectionViewDelegate

Parameters:

collectionView - This UICollectionView

indexPath - NSIndexPath of the item to perform the action on API-Since: 16.0
