问题描述

我有一个客户，该客户的设备具有自己的内置wifi热点，他希望将其连接到iPad 4G vie wifi并通过蜂窝连接同时转发数据. IOS是否支持此功能，如果可以，您可以向我指出相应的文档.任何建议表示赞赏.

I have a customer who has a device that has its own builtin wifi hot spot and he would like to connect it to an iPad 4G vie wifi and forward data at the same time through the cellular connection. Is this supported in IOS and if so can you point me to the appropriate documentation. Any suggestions are appreciated.

推荐答案

与Android相比，iOS支持同时运行多个网络适配器.有必要编写与BSD套接字一起使用的C代码，进行枚举，绑定和处理网络接口更改.

Comparing to Android, iOS supports simultaneous work of multiple network adapters. It's necessary to write C code working with BSD sockets, doing enum, bind, and handling network interface changes.

顺便说一句，在意识形态上继续在C/C ++中使用本机BSD功能非常重要，否则，谁知道Apple可能会在5到10年内完全取消对BSD套接字的支持:-)

By the way, it's ideologically very important to continue using that native BSD functionality in C/C++, otherwise, who knows, Apple may in 5-10 years remove support for BSD sockets completely :-)
