ZIndexedGroupView

@objcMembers public final class ZIndexedGroupView: UIView

UIView which only holds views that conform to ZIndexedView, where views are ordered in the subview list by their zIndex property. This causes each view to be rendered and hit-tested inside ZIndexedGroupView based on their zIndex.

Note

All views should be added via upsertView(:). Using any other insertion method on this class may have adverse effects. Adding any view other than one that conforms to ZIndexedView will result in an app crash.

Super

• hitTest(_:with:)

  Allows for hit testing while sub views are outside the bounds of a groupView.

  Declaration

  Swift

  public override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView?

Public

• upsertView(_:)

  Inserts or updates a UIView in this group, where it is sorted amongst other subviews based on its zIndex.

  Declaration

  Swift

  public func upsertView<T>(_ view: T) where T: UIView, T:ZIndexedView
