when the apple review team review our app，they point out that our  app uses a background mode but does not include functionality that requires that mode to run persistently。but in fact，when the app in background ，the app need data update to make the function of  trajectory replay come ture。in fact， we have added function when the app  is in background mode。we have point out the point to them by email。but they still have question on the background mode，we are confused，does anyone can help me，i still don't know why do review team can't find the data update when  the app is in background and how do i modify the app，or what is the really problem they refered，do i misunderstand them？
the blow is the content of the review team email：
We found that your app uses a background mode but does not include functionality that requires that mode to run persistently. This behavior is not in compliance with the App Store Review Guidelines.
We noticed your app declares support for location in the UIBackgroundModes key in your Info.plist but does not include features that require persistent location.
It would be appropriate to add features that require persistent use of real-time location updates while the app is in the background or remove the "location" setting from the UIBackgroundModes key. If your application does not require persistent, real-time location updates, we recommend using the significant-change location service or the region monitoring location service.
For more information on these options, please see the "Starting the Significant-Change Location Service" and "Monitoring Shape-Based Regions" sections in the Location Awareness Programming Guide.
If you choose to add features that use the Location Background Mode, please include the following battery use disclaimer in your Application Description:
"Continued use of GPS running in the background can dramatically decrease battery life."
Additionally, at your earliest opportunity, please review the following question/s and provide as detailed information as you can in response. The more information you can provide upfront, the sooner we can complete your review.
We are unable to access the app in use in "http://www.wayding.com/waydingweb/article/12/139". Please provide us a valid demo video to show your app in use.
For discrete code-level questions, you may wish to consult with Apple Developer Technical Support. When the DTS engineer follows up with you, please be ready to provide:
- complete details of your rejection issue(s)
- screenshots
- steps to reproduce the issue(s)
- symbolicated crash logs - if your issue results in a crash log
If you have difficulty reproducing a reported issue, please try testing the workflow as described in <https://developer.apple.com/library/ios/qa/qa1764/>Technical Q&A QA1764: How to reproduce a crash or bug that only App Review or users are seeing.
