Alex Hill d9d9a29365 [tvOS] Fixes errors when building against tvOS SDK (#728)
* [tvOS] Fixes errors when building against tvOS SDK

* Update CHANGELOG.md

* [tvOS] Fixes implicit conversion between UIViewAnimationCurve +
UIViewAnimationOptions

* Enable tvOS deployment target in Texture.podspec (for CI)

* [ASMultiplexImageNode] Fixes typo

* [tvOS] Fixes warnings related to @available guards in Xcode 9
[ASMultiplexImageNode] Enables support for Photos framework on tvOS 10+

[ASMultiplexImageNode] Fixes comment depth

[ASAvailability] Adjust logic in AS_AVAILABLE_IOS_TVOS to account for
both versions
Adjusts API_AVAILABLE to minimum deployment target

* [ASAvailability] Update AS_AVAILABLE_XXX fallbacks to function more like
the built-in solution (more accurately target OS by checking target)
Change AS_AVAILABLE_IOS -> AS_AVAILABLE_IOS_TVOS in places that shoud
allow for both

[ASAvailability] Simplify AS_AVAILABLE_IOS_TVOS

* [ASControlNode] Adds missing 'super' call in -[ASControlNode didLoad]
when targeting tvOS

* Fix API_AVAILABLE iOS requirement

* [ASDisplayNode] Fixes last of the linker warnings related to category
overrides. Removes methods already implemented in
ASDisplayNode+UIViewBridge category.
[ASControlNode] Moves tvOS category declaration to ASControlNode header
[ASImageNode] Moves tvOS category declaration to ASImageNode header
[ASControlNode+Private] Adds private category for ASControlNode to
access private selectors

* [NSParagraphStyle+ASText] Fixes typo related to testing

* [ASControlNode] Re-add helpful comment

* [ASTextKitCoreTextAdditions] Adds mappings for kCTParagraphStyleSpecifierMinimumLineSpacing, kCTParagraphStyleSpecifierMaximumLineSpacing, kCTParagraphStyleSpecifierLineSpacingAdjustment when mapping CTParagraphStyle onto NSParagraphStyle
[ASTextNode] Uses CoreText-cleansed attributed string when assigning ascender/descender to avoid crash when a CTParagraphStyle is passed as an attribute

* [AsyncDisplayKit] Update project file to include new/deleted files

* [ASControlNode+tvOS] Add missing Foundation import (whoops!)
[ASImageNode+tvOS] Add missing Foundation import (whoops!)

* Update podspec to only link AssetsLibrary framework on iOS

* [ASTextKitCoreTextAdditions] If kCTParagraphStyleAttributeName key-value
evaluates to an NSParagraphStyle, pass through to cleansed attributes. This
fixes a bug that would occur if a CTParagraphStyle was passed as an
attribute _alone_ (would not be caught by unsupported attributes
check)

* [ASMultiplexImageNode] Bump availability check to support < Xcode 9

* [ASTraitCollection] Fixes typo that was causing build to fail

* Clean up formatting to adhere to character/line limit + braces
