Our app displays maps from different venues. A feature I’m building lets users view sales and see the store’s location on the map. Some maps have stores in more than one location or a large store with the sale location in multiple locations. Zooming to one location isn’t hard, but how to determine the zoom level when I need to show multiple locations?

The easiest way to do this is to allow the Mappedin SDK to perform the calculations for you. You can use the [MPICamera.focusOn()](https://docs.mappedin.com/ios-sdk-api/v5/latest/documentation/mappedin/mpicameramanager/focuson(targets:options:callback:)/) method, which accepts multiple nodes or polygons. When you pass in more than one location the camera pans and zooms so that all locations on the map are visible. Have a look at [Focus the Camera on Targets](https://developer.mappedin.com/ios-sdk/v5/camera-controls/#focus-the-camera-on-targets) in our Camera Guide.

Always nice to let the SDK do the work. 😉 That’s what I needed.
