* [MaskedTransition] Convert motion spec to an Objective-C static class.
The interchange library will soon be dropping support for static spec initialization in favor of runtime APIs. This change moves the MaskedTransition off of all macro-based APIs.
* Fix API name.
* Fix type.
* Types.
This bug was introduced by the upgrade to MotionTransitioning 4.0. 4.0 requires that if a presentation controller implements MDMTransition, that its start method eventually invokes transitionDidEnd.
All examples now have at least the required `+catalogBreadcrumbs` and `+catalogIsPrimaryDemo`. All examples in the same breadcrumbs path have only one primary demo. There should be only one `-catalogDescription` attached to the primary demo.
Closes#1897
* Add Masked Transition component.
This component makes it possible to present a view controller from a source view, such as a floating action button, using a masked reveal transition.
This component depends on Material Motion's Transitioning, MotionInterchange, and MotionAnimator libraries.
The component itself is a Transition instance and can be used like this:
vc.transitionController.transition = MDCMaskedTransition(sourceView: fab)
present(vc, animated: true)
The component's motion is defined in its motion spec and was extracted directly from the Material motion spec.
The transition supports the following contexts:
- Fullscreen
- Bottom sheet
- Floating card
- Bottom toolbar
* Code review feedback.
* Add README.md.
* Copy the frame calculation block.
* Reword the overview to reduce implementation details.
* Remove scrim sharing and document full screen behavior.
* Audit rect math and remove example debug logs.
* Update to use hypot.
* Remove presentation controller storage.
* Update podspec with new MotionTransitioning dependency.
* Fix autoresizing bugs and update header import names.
* Fix floating point conversion warning.
* Use bottomCard spec for all positions.
