init(overlay:)
Creates and returns the overlay renderer and associates it with the specified overlay object.
Declaration
init(overlay: any MKOverlay)Parameters
- overlay:
The overlay object to use when drawing the overlay content on the map. This object provides the data needed to draw the overlay’s shape. The overlay renderer stores a strong reference to this object.
Return Value
An initialized overlay renderer object.
Discussion
Initially, the overlay renderer assumes that the overlay is fully opaque and that it has a content scale factor of 1.0. You can change these values as needed using the alpha and contentScaleFactor properties.
