There are multiple ways to instantiate a ReactionButton, using a frame, storyboards, or an empty convenience initializer.

2. Delegate

The ReactionButton has a delegate to communicate events of option selection, option focus, and cancel of actions. To use it, set the ReactionButtonDelegate conform as a delegate.

let buttonSample = ReactionButton(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
buttonSample.delegate = self
view.addSubview(buttonSample)

3. Custom layout instance

ReactionButton allows customization of the layout with the help of ReactionButtonDelegateLayout. To use it, please conform to that protocol and set it as delegate (Same pattern as UICollectionView).

func ReactionSelectorConfiguration(_ selector: ReactionButton) -> ReactionButton.Config {
  ReactionButton.Config(spacing: 2,
                        size: 30,
                        minSize: 34,
                        maxSize: 45,
                        spaceBetweenComponents: 30)
}
