* Renamed range update callbacks
We finally settled on
didEnter/ExitDisplayState
didEnter/ExitPreloadState
didEnter/ExitVisibleState
This change is meant to unify the range update methods to relate to each
other and hopefully be a bit more self explanatory.
* Guarantee interface callbacks happen on main.
* move fetchData / clearFetchedData to default implementations
* Move deprecated methods to new deprecated category
* Don't bring in cocoapod change.
* Nits
* Capetalize
* [ASVideoNode] Change superclass to ASNetworkImageNode so that ASVideoNode can be its own placeholder
- remove _placeholderImageNode property of ASVideoNode (use self.image now instead)
- move layoutSpecThatFits: code to calculateSizeThatFits: & layout: methods as ASImageNode uses calculateSizeThatFits:
* [ASVideoNode] Tweaks to the definition of the delegate protocols to integrate with ASNetworkImageNode (superclass)
* Removed play button from ASVideoNode
* Removed play button tests
* added some checks in ASVideoPlayerNode
* added new delegate method for time formats
- Simplified visibility state change handling.
- Placeholder image is now updated after switching assets.
- Improves memory usage by clearing the placeholder image in clearFetchedData.
Unclear why the framework target required these seemingly unrelated changes to Collection
classes, but I modeled them after related files and it seems cleaner now (passes tests & framework target)
