MKCustomOverlayMBS.canReplaceMapContent as Boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	MapKit	MBS MacFrameworks Plugin	19.2	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

a Boolean indicating whether the overlay content replaces the underlying map content.

true if the map view can skip the loading and drawing of the underlying map tiles or false if the map tiles should still be drawn.

The map view uses the return value of this method as a hint to determine whether it should load and render its tiles. If your overlay covers its designated region entirely with opaque content, and effectively replaces the content of underlying map tiles, implement this method and return true. Doing so alleviates the need for the map to render its tiles.
If you do not implement this method, or if you return false from it, the map view continues to load and render its tiles.
