GMSMapView Energy Impact

Question

I'm currently using a GMSMapView in my swift app, and the energy impact is never decreasing ( as the CPU usage or Memory usage ).

Did anyone already faced this issue ?

Answer 1

I Found the answer myself. It is related to GMSMarker.tracksViewChanges property.

Turning it to false for all added markers has released the CPU.

Answer 2

Make false of GMSMarker()'s object property tracksViewChanges & tracksInfoWindowChanges

let placeMarker = GMSMarker()
placeMarker.tracksViewChanges = false
placeMarker.tracksInfoWindowChanges = false

It will bringdown energy impact clock indictor.

I was already using tracksViewChanges property but now added tracksInfoWindowChanges as false, and that is showing significant improvement. – Delphiadelphic

Answer 3

I found google maps to consume to much memory as well. Changing tracksViewChanges worked for me as well.

Another approach that I have tried when the rendering was taking to long, is to split the rendering of the markers or views in the map.

You can use the delegate methods of GMSMapView

• mapViewDidStartTileRendering(_mapView: GMSMapView) and
• mapViewDidFinishTileRendering(_ mapView: GMSMapView)

to know when the render has finished and add new elements.
