Not able to navigate in Skobler Offline Mode iOS

Question

I am using SKMaps and SDKTools provided by Skobbler to render maps, calculate and navigate routes.

By referring to their Demo Project, I am able to download map package for offline usage. However I am not able to navigate or render the downloaded package.

Before downloading map package this is what I do : -

[SKMapsService sharedInstance].connectivityMode = SKConnectivityModeOnline;

Once downloading of map package is finished , here is what I do : -

[[SKMapsService sharedInstance].packagesManager addOfflineMapPackageNamed:code inContainingFolderPath:path];

But it does not calculate the route .

Any help?
