My application is under study if I can do it because there is some issues I do not know if I Can do it .
Is there any solution to capture device movement with Core Motion when the screen is locked or the app in background ?
I know there is some background modes like audio - location update - voip ...etc .
How to use accelerometer events in background by update location every second "keep my app alive"when the device is switch off and going to switch on can I run the app in background automatically ?
thank you for helping me
