TransformableView

Draggable, resizable and rotatable UIView implemented using protocols in Swift. Uses RxCocoa, RxGesture and RxSwift to avoid protocol extension restrictions.

Usage

TransformableView is a composition of DraggableView, ResizableView and RotatableView. Implement desired protocol as needed.

class View: UIView, TransformableView {}

class NonRotatableView: UIView, DraggableView, ResizableView {}

Protocols require var disposeBag: DisposeBag { get } and include optional func didUpdate(frame: CGRect) and func didUpdate(rotation: CGFloat) methods.

Finnaly, add gesture handling

view.addGesturesHandling()

Example
