The `UIReactionControl` class implements common behavior for reaction elements. It mainly defines two methods:
|
|
|
|
- `setup`: Manage the view hierarchy by adding and/or removing elements.
|
|
- `update`: Layout the view hierarchy and update state.
|
|
|
|
You should override these methods if you subclass the `UIReactionControl`.
