CCNA, CCNP, MCSA, CCNA Final Exam, All Answer Test Module With 100/100

Hallo experts, I've tested what's happing with my app when the iPhone is switched off while the app is active. For this purpose I logged the callback methods of the app's lifecycle in the xcode debugger console.

I was just wondering if it was possible to make an iOS app that would track your location via GPS while it was in the background. I tried this with the built-in app "Maps", but to no avail. If this is possible, it would be great if you could refer me to some sample code, documentations, or tutorials! (if this is a duplicate, please let me know and I will remove it) Source: Tips4all
