苹果审核被拒

app审核时收到下面的邮件，大概意思是需要我回复app在哪里用到了后台定位功能：

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其实都没有用到后台定位，打开代码发现

不小心把 Loacation updates 选中了，如果没有用到后台定位，把它取消掉重新审核就可以了不需要回复苹果的邮件。
