@MainActor
open class FUIActivityControl : NibDesignable, FUIBackgroundSchemeSupporting

FUIActivityControl is a stand-alone component supporting user activities. By default, it supports phone, email, message, videoCall. FUIContactCell embed with a FUIActivityControl by default.

Code usage:

 //You can create your own activity object if you want.
 let myCustomActivity = FUIActivityItem(icon: UIImage(named: "asset"), identifier: "mycustomer.twilio")
 let activities: [FUIActivityItem] = [FUIActivityItem.phone, FUIActivityItem.message, myCustomActivity]

 //Create a FUIActivityControl object.
 let activityControl = FUIActivityControl()
 activityControl.addActivities(activities)
 activityControl.delegate = self

 //Optionally, set an item size (if nil, intrinsic size of image will be used)
 activityControl.itemSize = CGSize(width: 44.0, height: 44.0)

 //Optionally, set a limit to visible items (useful for hiding items in `.compact` horizontal mode)
 activityControl.maxVisibleItems = 3

 //Optionally, set the inter-item spacing (useful for showing more items in `.compact` horizontal mode)
 activityControl.spacing = 10.0

 //Implement this method in your class to handle action.
 func activityControl(_ activityControl: FUIActivityControl, didSelectActivity activityItem: FUIActivityItem) {
     switch activityItem {
         case FUIActivityItem.phone:
            //do something
         case FUIActivityItem.message:
            //do something
         case myCustomActivity:
            //do something
         default:
            break
     }
 }

## Attention

The delegate object with type FUIActivityControlDelegate is declared as a weak reference. So on deallocation it will be automatically set to nil. To keep it alive as expected, developer should retain the delegate object during its whole execution scope.
