[PrasadPotale]

Found few crashes on Crashlytics, with following details, any help about the cause of issue, its occurring when we tap on map.

I get the same thing in a few scenarios. It seems to happen when I push or present a new view controller and usually only when I have GPS turned on.

Have you found any solution to this?

[PrasadPotale]

No I've posted this question on Stack overflow as well, but didn't get any response yet.

I'll update you, if I found any solution for it. Also let me know if you found any solution.

Marius Ursache​Ryan Olson​Divesh Goyal​ Hey guys, can you please help us to identify this issue.

[RyanOlson1]

Can you try turning hit-testing off on a per-layer basis to narrow down what layer is causing the crash?

[ChristopherMilack1]

Hey Prasad/Ryan,

Sorry to hijack this thread but I've run into a similar issue and had some detailed repro cases that might be helpful.

This was my workflow:

• Show view controller with AGSMapView in navigation controller (Location Display turned on) -
  • Do not interact with the map view at all
• Push a new view controller on the navigation controller
• Click back to return to the map view controller

At this point, if GPS is still on and the users location is offscreen, I will get a similar crash when I tap the map. However, if I pan the map first, then tap, I have no issues.

As a workaround, I started shutting off the GPS before pushing the new view controller and that resolved my issues.  It's been a while since I did that work but I did the exact test you described (removing layers), and the crash did not seem to correlate to any specific layer.  I can run these tests again if it would be helpful.

Here's another post I made when this first happened. The crash output was slightly different but the issue seemed to be the same. This frame buffer exception was consistent and repeatable but the _platform_memmove crash that Prasad was seeing was more intermittent for me. Both occurred when tapping on the map after returning from another view controller.

Frame_buffer_OGL::init_ FAILED when tapping map

Hope that is helpful.

Hi Chris, I'll try the scenario you have mentioned, and let you know, if I can reproduce it.

Hello Ryan Olson,

Thanks for replying, following is the code which I have used to add Picture Marker Symbol, the issue is random and when I tap on the marker the above crash issue is occurring,

self.markerGraphicsLayer = AGSGraphicsLayer(fullEnvelope:envelop ,renderingMode:AGSGraphicsLayerRenderingMode.Dynamic)

self.agsMapView.addMapLayer(self.markerGraphicsLayer, withName:Constants.graphicsLayerNames.MarkerGraphicsLayer)

func createMarkerGraphicsWithBadgeCount(point:AGSPoint,image:UIImage ,graphicAttributes :[NSObject:AnyObject] )

    {

var graphicPoint:AGSPoint!

        var graphicSymbol:AGSPictureMarkerSymbol!

graphicPoint = AGSPoint(x: point.x, y:point.y, spatialReference:self.agsMapView.spatialReference)

        graphicSymbol = AGSPictureMarkerSymbol(image:image)

        let graphics = AGSGraphic(geometry: graphicPoint, symbol:graphicSymbol, attributes:graphicAttributes)

        self.markerGraphicsLayer.addGraphic(graphics)

}

//Delegate method to handle tap on marker

func didTapOnGraphics(graphic:AGSGraphic, coordinate:CLLocationCoordinate2D)

    {

//Here new controller will be presented

}

[RyanOlson1]

can you try AGSGraphicsLayerRenderingMode.Static?

[PrasadPotale]

Now I've changed it to Static mode but now if I rotate map, markers also getting rotated, I'll test more on it and let you know, if it fixes that crash or not. Thanks.
