IOS上架被拒----如何修改使用摄像头的权限提示？

Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage

We noticed that your app requests the user’s consent to access their camera but does not clarify the use of this feature in the permission modal alert.

Please see attached screenshots for details.

Next Steps

To resolve this issue, please revise the permission modal alert to specify why the app is requesting access to the user's camera.

大概意思是说APP在使用摄像头时，使用权限提示没有说清摄像头具体用于哪些情况。
