This avoids CoreAnimation from capturing the name from a background thread deep within the internals
of AVPlayerLayer, which commits transactions off the main thread. If the main thread is also accessing
properties that require the lock, in very specific app architectures relying on AVPlayerLayer, this
can cause a deadlock.
The "name" property is primarily used by ASDK's unit test infrastructure, so I'm leaving it in place for
that purpose - and it may still be used for debugging, if someone wants to set it. It will remain
possible to get the node from a layer or view with asyncdisplaykit_node, and access name from there.
Later, this will be added to ASViewController. Right now it is not hooked up to drive anything.
It will become the codepath that drives calls like -fetchData and -clearContents.
- Cell node automatically notifies the delegate after a relayout (via -setNeedsLayout) that results in a new size. Confirming to ASCellNodeDelegate; ASTableView and ASCollectionView reload the calling cell upon notifications. These views automatically set themselves as delegate of every node.
- The result is that ASCellNode subclasses don't need to manually notify the containing view. Thus, `-relayoutItemAtIndexPath` and `-relayoutRowAtIndexPath` are removed.
- Kittens example is updated to reflect the change.
ASNetworkImageNode defers to ASImageNode to return its calculatedSize. ASImageNode returns the size of its image. There is a good chance that ASNetworkImageNode hasn't downloaded its image yet when calculatedSize is called, so it returns a size of CGSizeZero.
On top of that, it is possible that the size of the image is not actually the size that we wish to display in our node.
I've added an "expectedImageSize" property that can be used to determine the calculatedSize of an ASNetworkImageNode.
- -layoutSpecThatFits: must return an ASLayoutSpec.
- Move ASDisplayNode's -measureWithSizeRange: redeclaration to ASDisplayNode.h.
- Rename ASStackLayoutChild.h to ASStackLayoutDefines.h.
- Rename ASStaticLayoutSpecDimension.h to ASRelativeSize.h.
- Don't import ASLayout.h in other headers to prevent circular inclusions.
- Explain use cases of ASLayout's initializers.
- Clean up ASInternalHelpers.h.
- constrainedSizeForCalculatedLayout is of type ASSizeRange.
- calculatedLayout is better explained.
- Since ASLayout is cached and reused, its position property is mutable.
