Is it possible to detect the user's moving activity on the background?

algorithm, cocoa-touch, ios, objective-c, swift

Solution

There is coprocessor m7(+) in iPhones upper 5s. It gives you possibility to get device motion. Just

import CoreMotion

in your file.

Create a CMMotionActivityManager object:

let motionActivityManager = CMMotionActivityManager()

Check if it`s available on your device: `motionActivityManager.isActivityAvailable()`

Use this method:

 motionActivityManager.startActivityUpdates(to: OperationQueue.main) { (activity) in
        if (activity?.automotive)! {
            print("User using car")
        }
        if (activity?.cycling)! {
            print("User is cycling")
        }
        if (activity?.running)! {
            print("User is running")
        }
        if (activity?.walking)! {
            print("User is walking")
        }
        if (activity?.stationary)! {
            print("User is standing")
        }
        if (activity?.unknown)! {
            print("Unknown activity")
        }
    }

It would return you types of user activity.

Problem

I want to develop an app that detecting the user's moving way (walking, cycling, driving etc...) and send a specific `UILocalNotification` for each activity type. My question is: is it possible to detect it on the background (when the app is completely closed) without draining the device's battery? What will be the best way to do it? Thank you!
