`– performBatchAnimated:updates:completion:`

Perform a batch of updates asynchronously, optionally disabling all animations in the batch. This method must be called from the main thread. The asyncDataSource must be updated to reflect the changes before the update block completes.

Parameters

`animated`	NO to disable animations for this batch
`updates`	The block that performs the relevant insert, delete, reload, or move operations.
`completion`	A completion handler block to execute when all of the operations are finished. This block takes a single Boolean parameter that contains the value YES if all of the related animations completed successfully or NO if they were interrupted. This parameter may be nil. If supplied, the block is run on the main thread.

Declared In

ASCollectionView.h

`– performBatchUpdates:completion:`

Parameters

`updates`	The block that performs the relevant insert, delete, reload, or move operations.

Parameters

`completion`	block to run on completion of asynchronous loading or nil. If supplied, the block is run on the main thread.

Discussion

Warning: This method is substantially more expensive than UICollectionView’s version.

`– reloadData`

Reload everything from scratch, destroying the working range and all cached nodes.

- (void)reloadData

Discussion

Warning: This method is substantially more expensive than UICollectionView’s version.

ASCollectionView.h

`– reloadDataImmediately`

Reload everything from scratch entirely on the main thread, destroying the working range and all cached nodes.

- (void)reloadDataImmediately

Discussion

Warning: This method is substantially more expensive than UICollectionView’s version and will block the main thread while all the cells load.

Declared In

`– relayoutItems`

Triggers a relayout of all nodes.

- (void)relayoutItems

Discussion

This method invalidates and lays out every cell node in the collection.

`– waitUntilAllUpdatesAreCommitted`

Blocks execution of the main thread until all section and row updates are committed. This method must be called from the main thread.

- (void)waitUntilAllUpdatesAreCommitted

`– registerSupplementaryNodeOfKind:`

Registers the given kind of supplementary node for use in creating node-backed supplementary views.

- (void)registerSupplementaryNodeOfKind:(NSString *)elementKind

Parameters

`elementKind`	The kind of supplementary node that will be requested through the data source.

Discussion

Use this method to register support for the use of supplementary nodes in place of the default registerClass:forSupplementaryViewOfKind:withReuseIdentifier: and registerNib:forSupplementaryViewOfKind:withReuseIdentifier: methods. This method will register an internal backing view that will host the contents of the supplementary nodes returned from the data source.
