app審核時收到下面的郵件，大概意思是需要我回復app在哪里用到了后臺定位功能：
We began the review of your app but aren't able to continue because we need additional information about your app. At your earliest convenience, please review the following questions and provide as much detailed information as you can.
- Does this app detect startMonitoringForRegion:, startRangingBeaconsInRegion:, or both?
- What is the user experience when the app detects the presence of a beacon?
- What features in this app use background location?
- If this app uses 3rd party SDKs for iBeacons, please provide links to their documentation showing that background location is required for it to function.
Please reply to this message in the Resolution Center with the requested information.
可是app其實都沒有用到后臺定位，打開代碼發現
不小心把 Loacation updates 選中了，如果沒有用到后臺定位，把它取消掉重新審核就可以了不需要回復蘋果的郵件。
