How to remove a webmap from AGSMapView programatically

HumzaAkhtar — Fri, 10 May 2013 01:24:48 GMT

Hi,

It seems like a basic question but does any one has any idea on how to remove a webmap from a mapview. By removing I mean deleting the webmap? There seems to be no 'Remove Webmap' method available in the AGSWebMap class.

thanks

AGSWebMap is nothing but a container with multiple layers which you open into map view (AGSMapView). In order to remove all layer from a map you call reset on map view ([self.mapView reset]).

If you want to load another webmap in the same map view then you just open another webmap and it'll take care of removing layers of earlier webmap.

Hope this helps!

Hi Nimesh,

After upgrading to 10.1.1 Update 1, using the [mapView reset] causes the application to crash.

And gives the error :

libc++abi.dylib: terminate called without an active exception

Below is the Stack :

Ahmed,

Can you provide a small testcase to repro this error? I can't repro it on my end.
