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!
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.
Regarding the user activity which can be handled in background tasks are the below once which does not mention about (walking, cycling,driving etc...)
Implementing Long-Running Background Tasks
For tasks that require more execution time to implement, you must request specific permissions to run them in the background without their being suspended. In iOS, only specific app types are allowed to run in the background:
