iOS审核被拒“VoIP”

Guideline 2.5.4 - Performance - Software Requirements

Your app declares support for VoIP in the UIBackgroundModes key in your Info.plist, but it does not include any Voice over IP services.

Next Steps

To resolve this issue, please revise your app to either add VoIP features or remove the "voip" setting from the UIBackgroundModes key.

We recognize that VoIP can provide "keep alive" functionality that is useful for many app features. However, using VoIP in this manner is not the intended purpose of VoIP.

Request a phone call from App Review

At your request, we can arrange for an Apple Representative to call you within the next three to five business days to discuss your App Review issue.

大致的意思是 ：
请修改你的应用程序中添加VoIP功能或删除“VoIP”从uibackgroundmodes键设置。
我们认识到，网络可以提供“活下去”的功能，对于许多应用程序的功能是有用的。然而，这种方式是不使用VoIP VoIP的目的。
在plist中Required background modes ：App provides Voice over IP services
