BlueprintView

BlueprintView is a UIView subclass that displays a Blueprint element hierarchy.

Creating a BlueprintView instance

init(element:) instantiates a new BlueprintView with the given element:

let rootElement = Center(
    Column { column in

        column.layout.horizontalAlignment = .center
        column.layout.minimumVerticalSpacing = 12.0

        column.add(child: Label(text: "Hello, world!"))
        column.add(child: Label(text: "This is a label"))
    }
}

let blueprintView = BlueprintView(element: rootElement)

Updating the element hierarchy

A BlueprintView instance can be updated after initialization by assigning the .element property:

blueprintView.element = Label(text: "This is a new element")

Updates can be animated within an animation block:

UIView.animate(withDuration) {
    blueprintView.element = Label(text: "This is a new element")
}

See the documentation for ViewDescription for more information about transitions.
