A couple months ago, I found a way to get the location update from iOS 7 and 8 even when the app is not active on foreground and not in the background. Yes, you may get the GPS coordinates from the iOS devices even when the app is killed/terminated either by the user or the iOS itself.
Here are the steps to use this solution:-
1. Download the project from Git Hub.
2. Change to your own Bundle Identifier (If need to)
3. Connect your iPhone with your mac.
4. Launch the app into your iPhone.
5. Killed the app. (Double tap and remove the app from the App Preview)
6. Travel around with your iPhone for a few days.
7. Download the LocationArray.plist to inspect from the File Sharing interface in iTunes.
8. From the PLIst, you will see something like the screen shot below:-
When you see the key “UIApplicationLaunchOptionsLocationKey” under “Resume“, it means that the iOS has relaunched the app after the devices has moving significantly from the last known location. If you create a new location Manager instance, you will get new location from delegate method “didUpdateLocations“.
For the detail information, Please read: Getting Location Updates for iOS 7 and 8 when the App is Killed/Terminated/Suspended.
Currently, I am working as a Senior iOS Developer in Singapore. I might not be free to keep this solution updated. Please check the changes on the latest iOS to make sure that the solutions works well. Thanks.
Thanks.
