* [ASCollectionView] Fix index space translation of Flow Layout Delegate methods.
This includes a few other cleanups, including overflow of signed integer indices.
* [ASCollectionView] Improve code sharing of UIKit size method calls; ensure delegate invalidation re-fetches supplementary sizes too.
* [ASCollectionView] Final method ordering and doc-comment for new _sizeForUIKitCellWithKind:atIndexPath: method.
* [PINCache] Set a default .byteLimit to reduce disk usage & startup time.
This default is fairly low - only 20MB - but for most apps with images
in the size range of 10-50KB, this is still 400-1000 images.
Once some optimizations land to PINCache, we'll match the PINCache
default of 50MB to ensure the default better serves users with larger
objects in the cache.
Apps should preferably set their own byteLimit to an optimal value.
@garrettmoon - one interesting question for us is the best place to
set .byteLimit as an app. Digging into the ASPINRemoteImageDownloader
and doing this type cast is a bit complicated, so a passthrough API
to get the PIN* objects directly might be worthwhile.

* Remove old unused code
* Add a changelog message
* Bump PINRemoteImage
* Huy's comments
* [ASCollectionNode] Add -isProcessingUpdates and -onDidFinishProcessingUpdates: APIs.
Over time, there have actually been a lot of legitimate uses for an API like this.
In fact, I'm not quite sure what has held us back from adding one!
I believe that at least some portion of -wait calls (even if less than 50%) could be
replaced with -onDidFinishProcessingUpdates:, which could potentially improve the
performance of applications using -wait by a significant amount.
Please take a close look at implementation correctness. Although I'm in a bit of a
rush, I'm aiming to make this properly documented and added a basic test -- but it
could certainly use some more detailed testing as a followup.
* [ASCollectionNode] Improvements to the implementation of -isProcessingUpdates and -onDidFinishProcessingUpdates:
* Add lock to ASMainSerialQueue count method.
* [ASTableNode] Implement -isProcessingUpdates and -onDidFinishProcessingUpdates:. Rename -waitUntil to consistent naming.
* Table and collection views to consider their content inset when calculating element size range
* Update CHANGELOG
* Address comments
* -[ASPagerNode currentPageIndex] to use pageSize instead of bounds
* Update documentation in ASPagerNode
* Minor change
After consulting Apple documentation and working with some a11y experts,
we've found that aggregating objects that have a11y labels but are not
themselves interactable is significantly preferred for these users.
It makes it much quicker to navigate scrolling content if VoiceOver only
stops to select entire cells, and then allows drilling down into the cell
to select individual components. This implementation achieves that behavior.
We should consider enabling isAccessibilityContainer by default on ASCellNode.
This would be an improvement for 95% of a11y use cases. Aggregation can be
enabled or disabled on any node.
- During the first layout calculation, measure more than just elements in the visible viewport.
- Remove unnecessary params in `-[ASCollectionLayoutState getAndRemoveUnmeasuredLayoutAttributesPageTableInRect`.]
- Add content offset bridging property to table and collection node
- And use it in `ASCollectionLayout` to avoid measuring unrelated nodes during the first layout.
- Update CHANGELOG and highlight deprecated methods
* Improvements in ASCollectionGalleryLayoutDelegate
- It now can handle section inset, as well as interitem and line spacings
- Other small changes
* Fix build failure and update file licenses
* Update CHANGELOG
* Minor change
* Another assertion on scrollable directions of gallery layout delegate
* Add ASCollectionGalleryLayoutSizeProviding
- This allows users to return different sizes based on certain conditions, such as the collection node's bounds or grid constants.
- ASPagerNode will also act as a size provider to ensure all pages have an up-to-date size that is its bounds.
* Update CHANGELOG
* ASPagerNode to use gallery layout delegate if told to
* Merge willUpdateWithChangeSet and didUpdateWithChangeSet delegate methods into one
- After #420, there is no change occurs between those 2 methods. Having them separately doesn't achieve anything and can cause confusions.
* Minor change
* Clean up ASDataController
- Parameters passed to ASDataControllerCompletionBlock are no longer used. Remove them.
- The value returned by _allocateNodesFromElements:andLayout:completion is not used. Remove it.
- Elements are not allocated and measured in batches anymore. Remove the code that does batch allocation.
- Remove RETURN_IF_NO_DATASOURCE. It's used only once and is not worth it.
* Remove +parallelProcessorCount
* Update CHANGELOG
* [ASCollectionView] Add delegate bridging and index space translation for missing UICollectionViewLayout properties
This is a first attempt at resolving #438.
I know there is already one similar method to do indexPath conversions, and that the #define for
accessing properties on the UICollectionViewFlowLayout should probably be moved somewhere else.
Looking for feedback on the general direction here. In particular, I'm a bit surprised that so much
has changed in how these calls occur, as I believe especially constrainedSizeForNodeAtIndexPath: is
now called with inconsistent index path spaces (but was not before this PR landed in March:
https://github.com/facebookarchive/AsyncDisplayKit/pull/3136/files)
Since the impact of mixing the spaces is fairly serious (can cause crashes), I'm also wondering if
I am misinterpreting some aspects of the code, or if maybe the crashing impact wasn't noticed yet.
* [ASCollectionView] Cleanup and final changes for UIKit passthrough fixes.
* Implement ASCollectionGalleryLayoutDelegate
- It arranges items of the same size into a multi-line stack (say photo gallery or pager). It takes advantage of the fact that its items always have a fixed size to measure as few items as possible while still being able to track their positions at all time. This helps reduce startup/reloadData time, as well as memory footprint.
- It then uses a measure range, which also works as a allocate range, to figure out which items to measure ahead of time. And it guarantees that each item is scheduled to measure only once.
- Lastly, ASCollectionLayoutDelegate has some new methods that allow delegates to hook up and stay ahead of layout attributes requests from the backing view. ASCollectionGalleryLayoutDelegate for example uses these methods to ensure elements that have their layout attributes requested are always ready for consumption, and to measure more elements in the background.
* Handle items that span multiple pages and other improvements in gallery delegate
* Minor fixes
* Fix failing tests
* Fix custom collection example
* Implement missing method in gallery layout delegate
* Fix warnings
* Some improvements
- Collection layout delegates must have a crollable directions property.
- Simplify gallery delegate by not storing unmeasured attributes since calling measure on already measured elements should be cache hits and super fast.
- Abstact some code in gallery delegate to ASCollectionLayoutState+Private and _ASCollectionGalleryLayoutItem.
- Other improvements in gallery delegate
* Fix file licenses
* Move measure range logic to ASCollectionLayout
* Track unmeasured elements
* Remove pending layout in ASCollectionLayout
* Get back pending layout because the timing to latch new data is not ideal
* Add ASCollectionLayoutCache
* Fix file licenses
* Fix xcodeproj
* Add async collection layout to examples/ASCollectionView
* Measure method in ASCollectionLayout to be a class method
* Encourage more immutable states
- Make -calculateLayoutWithContext: to be class methods in ASDataControllerLayoutDelegate and ASCollectionLayoutDelegate.
- Add layout delegate class and layout cache to ASCollectionLayoutContext+Private, to be use by ASCollectionLayout only.
- ASDataController no longer allocates all nodes but lets ASCollectionLayout determine.
- Add scrollableDirections to the layout context since it's often needed by the layout pass. Otherwise users have to wrap it in an info object.
- Update built-in layout delegates and CustomCollectionView example.
- Publish ASHashing. It might be helpful for clients that implement custom collection info objects.
* Remove additionalInfo property in ASCollectionLayoutState
* ASCollectionLayoutState to correctly filter unmeasured elements
* Add ASHashing to umbrella header
* Fix file licenses
* Add ASDispatchAsync and use it in ASCollectionLayout
* Improve code comment in ASCollectionLayoutState
This makes it much easier to use the ASCoreAnimationExtras method which offers by
far the most efficient way to display a stretchable image.
In the future, we should move that function to UIImage+ASConvenience or another
header where it can be more easily found and enjoyed!
* Minor refactors in ASCollectionView and its private cell classes
- `_ASCollectionReusableView` and `_ASCollectionViewCell` no longer expose getters for their collection element and cell node properties. This is to make sure that clients can only obtain elements from the visible map which is always the source of truth.
- Since the map can return `nil` for an element request, it's much safer to check and avoid adding/removing a nil pointer to an `NSArray`.
- Since we use a special way to check whether an object of kind of `_ASCollectionViewCell` or `_ASCollectionReusableView`, based on the assumption that these classes are subclass restricted, I added cast-or-return macros in the header files, closer to where the restrictions are declared.
* Add ASDynamicCastStrict
* Add element and node properties back to _ASCollectionReusableView and _ASCollectionViewCell
* Assert unexpected nil elements
* Always mark an element visible even if it is backed by an UIKit / non-_ASCollection* view
* Fix typo
* Remove unnecessary changes
* Dump mistakes
* Update CHANGELOG
* Can't track visibility of elements backed by non-_AS views
* Fix a crash in table view caused by executing an empty change set during layoutSubviews
- Previously, when a change set is empty, `ASDataController` forwards the change set to its delegate right away, without dispatching to its editing queue and then back to main.
- This behaviour can potentially cause bad internal states in UITableView which trigger a crash reported in https://github.com/TextureGroup/Texture/issues/83.
- Fix by still reusing the existing pending map, because the data source's state has not changed, but go through the editing queue and main queue tunnel.
* Update CHANGELOG
