LBMaps is a static library for iOS (iPhone aswell as iPad), providing additional features in Google Mapkit to your application. LBMaps is currently used in iStAnton, and is available on request from me. 

Some of the features include: 

• display of costum routes or paths
• display of costum POIs
• parsing of information from OSM
• real-time updating of information on the map (e.g. state of a slope,...)

Of course all features included in a standard MapKit Map, stay available.
