The Google Maps SDK for iOS currently supports markers, polylines and ground overlays. I suspect you're also working on tiled overlays, to be similar to the Android SDK.

All of these types of overlays are static - you add them once, and then aren't expected to update them often. The SDK is probably optimized to assume that these are not changed frequently.

It would be great if there was some way to support dynamic overlays. The highest-performance and most general way to support this would be to provide access to the underlying OpenGL context which the SDK uses to render the maps.

Perhaps the SDK could allow the caller to set a delegate/callback which is called at the appropriate point during the rendering cycle, providing details of the current camera etc, so that the app can render its content directly into the scene.

This would need to offer some way to get access to the OpenGL context being used by the maps SDK, so that the app could load textures and shaders etc.

Thanks,
