TileOverlay
An overlay that covers an area of the map with bitmapped tiles.
Declaration
class TileOverlay extends MapKitEventTargetOverview
You use tile overlay objects to represent your own tile-based content and to coordinate the display of that content on a map. Your tiles can supplement the underlying map content or replace it completely. You can use a single tile overlay object to represent all of the tiles at one or more zoom levels of the map.
