I want to show USA country map in offline mode in IOS mobile application. I have read documentation part of ArcGIS and they have mentioned that to achieve this thing, I need tpk file. So how I would generate tpk file of USA country.
You can create a tpk file with ArcMap or Pro. Check out these links.
Once created you can side load it to the device for use in your iOS app. Alternatively, you can also use the SDK's `AGSExportTileCacheTask` to generate tile package.
