JSONDrivenUI
Convert your json into native Views
Simply construct JSONDataView(json: Data) view to setup UI.
OK JSON but how?
- Specify your view's
type(ViewType) -
propertiesof it (ViewProperties ) -
values(like text, imageUrl, systemIconName, localImageName) (Values ) -
subviews(for stacks, list & scrollView)
