ios 关于用户地理位置这种用户信息，是如何规定的？

在设计 ios app 的时候，如果需要获取用户的地理位置信息，苹果是如何规定的？

我们的 app 由于在获取地理位置的时候，没有提示用户，被拒了。
并给了以下几点修改要求：

Your app enables the display of nearby users ’ locations on a map, but does not have the required privacy precautions in place.

Next Steps

It is necessary that you put all of the following precautions in place:

• Your app ’ s rating must reflect a “ Frequent/Intense ” setting for Mature/Suggestive Themes in iTunes Connect
• Include a privacy policy URL in the App Details page on iTunesConnect and ensure that the URL you provide directs users to your privacy policy
• Ensure that users have a mechanism to block other users
• Request users ’ s permissions to be have their location displayed on a map; users must have the option to decline this request
• Require users to manually check-in each time they wish to have their location displayed on a map; there should be no option to enable automatic check-ins

请问 detail 中的前两条是什么意思？
关于用户的地理位置信息，一般的应用应该如何处理？
