implement pulse effect on annotations

[odedharth]

Is there a way to implement a pulse effect on annotations in mapbox?

(something like this https://github.com/TransitApp/SVPulsingAnnotationView)

thanks

Except for the user location dot and the callout view, all annotations are drawn at the GL level and aren't readily accessible for these types of effects. The user dot currently does what you're asking, but drawing it on screen relies on hardcoded updates in MGLMapView.

Implementing arbitrary native views is covered in #1784.
