AGSMapView displaying gps location

JeffJackson — Thu, 07 Mar 2013 20:08:08 GMT

When you don't include the arcgis.bundle, you get a clean blue marker symbol when you display the gps location on the map. Is it possible to access that symbol or replace it?

Thanks,
Jeff

I believe this would be accomplished with the customViewForLocationDisplay or imageForLocationDisplay methods of the AGSLocationDisplayInfoTemplateDelegate protocol. Every AGSMapView instance has an AGSLocationDisplay, called locationDisplay, which has an AGSLocationDisplayInfoTemplateDelegate. It looks like you can easily write your own implementation of the AGSLocationDisplayInfoTemplateDelegate protocol and assign it to locationDisplay.

Actually, the AGSLocationDisplayInfoTemplateDelegate lets you customize the callout that is displayed when you tap the location indicator on the map. I would like to customize the location indicator itself.

My mistake. If you want to replace the default indicator graphics, you could move a copy of the bundle into your app directory, point to that bundle, open it with ctrl-click->Show Package Contents, and then replace the LocationDisplay___.png files with different graphics. I think that clean blue marker symbol is drawn on the fly if the LocationDisplay graphics / the bundle cannot be accessed, so the code for that drawing would be buried in the SDK.
