1、ipv6 被拒

最近新上传一个做直播的app，本地已经明确支持了IPv6，但是审核的时候被拒了，居然说是没有适配IPv6，好郁闷。上传了几次才搞明白，由于原来视频太大了，在美国压根就拉取不到视频。最后的解决办法就是，审核的时候再服务器上上传几个1分钟左右的视频，多点击播放几次就可以了。

Guideline 2.1 - Performance - App Completeness

Additionally, we discovered one or more bugs in your app when reviewed on iPhone running iOS 10.3.2 on Wi-Fi connected to an IPv6 network.

Specifically, your app displays the activity indicator indefinitely when we attempt to play any video content.

Please see attached screenshots for details.

2、提示缺乏各种安全的预防机制，还没有合适的提示语

- 在适当的地方给予一定的提示信息
- 安全预防机制已经有了，在上传材料的时候 将这些安全预防机制的流程传给App Store即可

Guideline 1.2 - Safety - User Generated Content

Your app enables the display of user-generated content but does not have the proper precautions in place.

Next StepsTo resolve this issue, please revise your app to implement all of the following precautions:

Require that users agree to terms (EULA) and these terms must make it clear that there is no tolerance for objectionable content or abusive users
A method for filtering objectionable content
A mechanism for users to flag objectionable content
A mechanism for users to block abusive users
The developer must act on objectionable content reports within 24 hours by removing the content and ejecting the user who provided the offending content
