Navigation app for iOS - Literature review Example This framework is designed to work with the newly introduced M7 coprocessor that is dedicated to handle motion sensors without reducing the battery performance of the device. It gives the developers accurate data about the users, which they can later make use of in their applications. For example, a developer can find out whether the device is currently with an individual who is in the act of walking, or with someone who is travelling in an automobile etc, without actually processing the accelerometer’s data. Core Motion Framework provides answers to such questions through constants defined by the classes of framework. â€Å"Now Core Motion has been around since iOS 4.0, but the iOS 7 includes the new classes needed to access data from the M7. The two main classes used here are CM Motion Activity Manager and CM Motion Activity. These two classes work hand in hand to make work the motion activity updates† (Graves 2014: 1). Most iPhones contain an accelerometer and 3 axes Gyroscope built into them, which provide the device with 6 operational axes when used together. This axis data and motion data populated by the M7 co processor could be used along with Map kit or any other third party Map API to create great navigation apps. The gyroscope data as well as gravity sensor data are also used for building motion sensitive gaming-applications. Various class references of Core Motion framework include â€Å"CMAttitude, CMAccelerometerData, CMDeviceMotion, CMGyroData, CMLogItem, CMMagnetometerData, and CMMotionManager† (Aguinaga 2013: 9). The Map Kit framework is used for embedding custom maps into iOS application windows. The 5.1 version and the previous ones basically made use of Google Maps API for displaying the maps through the MapKit framework. â€Å"This framework also provides support for annotating the map, adding overlays, and performing reverse-geocoding lookups to determine placemark information for a given map
