Google launched an SDK to enable developers to integrate with the Google Maps app which has just been launched for iOS.

The search giant was replaced as the native apps partner for Apple in iOS 6, in favour of Apple’s own – much criticised – mapping service.

Developers will now have the option of integrating Google Maps with the apps they are building for the Apple platform, in place of Apple Maps.

The SDK includes vector-based maps which allow developers to add 2D and 3D navigation to their apps, as well as maps that rotate and tilt and with simple gestures.

Information such as traffic conditions, camera positions can also be delivered.

Access to API keys for the different elements of Google Maps is being rolled out to developers that register interest.

The Google Maps for iPhone app can also be launched via another iOS app using the URL scheme to complete a search, show Street View imagery or provide navigation.
