Nativescript Mapbox on iOS retain memory after navigation away

See original GitHub issue

I’m using Angular 2, with router-outlet navigation. My app is killed by the OS for using too much memory after I navigate away from the page with the MapBox map and return. It’s clear that the memory associated with the Mapbox instance is not being released.

I put a log statement in ngOnDestroy() and it is being called when I expect it to be. Is there anything I can do to force the SDK to release memory?

I’m instantiating the map via XML


    <GridLayout  #mapcontentview  rows="*" columns="*" >
        <Mapbox
            accessToken=MYTOKEN
            latitude="39.9780"
            longitude="-82.4182"
            zoomLevel="12"
            showUserLocation="true"
            (mapReady)="onMapReady($event)">
        </Mapbox>
     </GridLayout>

This component is instantiated in the page via Angular2 router-outlet navigation.

How can I further debug this issue?

Thanks for sharing, @simonettoa!

I’m about to release plugin version 4.0.0 which includes Mapbox iOS SDK version 4.0.0 which (as far as I can see from their changelog) contains a bunch of memory leaks. Perhaps that will help as well. Closing for now.

With the above referenced test app.

I do a GC on ngInit … I’m loosing only 5MB on a round trip. This is a big improvement over ~350MB I was loosing.

It is probably good enough for our application. But not for a full scale (web scale) production app.

I don’t think you should close this issue.
