ArcGIS Mapview decelerating/scrolling stop callback?

HarishChopra — Tue, 19 Nov 2019 22:04:08 GMT

Hi all,

I want to save viewpoint coordinates when map view had end decelerating.

I tried observing viewport change callbacks and also KVO for "navigating" but these are called on every movement thus making it slow.

So please let me know if there is any KVO property that I can observe to get callbacks only when map view scrolling had stopped.

Thanks is advance,
Harish

isNavigating will only fire when the map starts or stops navigating, not continuously. So you should observe that and when it's set to false, you know the map has stopped moving.
