UIViewController

public extension UIViewController
extension UIViewController: AlertViewPresenter

  • Loads the childViewController into the specified containerView.

    It can be done after self’s view is initialized, as it uses constraints to determine the childViewController size. Take into account that self will retain the childViewController, so if for any other reason the childViewController is retained in another place, this would lead to a memory leak. In that case, one should call unloadViewController().

    Declaration

    Swift

    func load(childViewController: UIViewController,
          into containerView: UIView,
          with insets: UIEdgeInsets = .zero,
          in viewPositioning: ViewPositioning = .front,
          layout: LayoutMode = .constraints,
          respectSafeArea: Bool = false)

    Parameters

    childViewController

    The controller to load.
    into

    The containerView into which the controller will be loaded.
    viewPositioning

    Back or Front. Default: Front
