Original User: technobratYou cannot directly consume MrSID files in Runtime SDK for iOS.You will need to either1) Publish the mrSID data through a mxd/msd file to an ArcGIS Server as a service (this would require you to have network connectivity to consume the service through the SDK). See this.2) Create a Tile Package using the mrSID data in ArcMap. You can then copy over the tilepackage to the device and access it even when the device is offline. See this.
