Prompt asking user if they want to continue letting your app collect background location - How often does this occur?

问题

As you probally already know, one of the new features in iOS 8 is that Apple will occasionally ask the user something along the lines of:

"Weather" has been using your location in the background. Do you want to continue allowing this?

How often does Apple ask this and how do they determine when to ask? I can't find any documentation and my own testing has shown that it can range quite a bit. Thanks in advance.

I have same problem with that alert.

When app request always authorization, OS will ask "Allow xxxApp to access your location even when you are not using the app?"

And a few weeks OS ask "xxxApp has been using your location in the background. Do you want to continue allowing this?" The second alert will show again every few weeks.

See some alert images at this web: https://support.apple.com/en-us/HT203033
