Multiple sub view can be added to the view controller, which is displayed when needed;

Multiple child viewcontroller can be added through Viewcontroller (parent) to control Sub view in the page, reducing the coupling of the Code;

By toggling, you can display different view, and replace the management of the previous Addsubview
