间歇性的“没有路由到主机"在iOS上，先关闭飞行模式再修复 [英] intermittent "No Route to Host" on iOS, flight mode off then on fixes
问题描述
我的iPhone应用程序使用UDP通过蜂窝网络进行通信.
My iPhone app uses UDP to communicate over the cell network.
它通常可以正常工作，除了有时操作系统在sendto调用上返回到主机没有路由"(65)，并且从那以后再也无法工作-即使关闭并重新启动，我仍然会遇到相同的错误.重新打开应用程序.但是，如果我切换飞行模式(大概是重置通讯栈)，然后返回应用程序，则一切正常.
It generally works, except that sometimes the operating system returns "No route to host" (65) on a sendto call, and it never works from that point onwards -- I just keep getting same error, even if I close and reopen the app. However, if I toggle flight mode (presumably resetting the comms stack) and then go back to app, everything works.
我已关闭WiFi，以便可以强制其使用蜂窝网络.另外，如果我让手机进入这种不工作状态并打开，例如Stocks应用程序，它会在连接和更新自身之前短暂地(大约1秒钟)说网络不可用".感觉Stocks应用程序中有一些代码可以识别问题并进行某种重设和重试.我想该应用程序使用TCP/IP与Web服务进行通讯.
I have WiFi switched off so that I can force it to use the cell network. Also, if I get the phone into this not-working state, and open, say, the Stocks app, it briefly says (for about 1 second) "Network Unavailable", before connecting and updating itself. It feels like there's some code in the Stocks app that recognizes the problem and does some kind of reset and retry. I suppose that app uses TCP/IP to talk to a web service.
谁能告诉我发生了什么事，或者我可以如何执行与我认为Stocks正在执行的相同的重置并重试"?任何想法表示赞赏:)
Who can tell me what's going on, or how I can do the same "reset and retry" that I think Stocks is doing? Any ideas much appreciated :)

推荐答案
事实证明，正在进行某些电源管理，该电源管理可能会破坏3G网络接口.备份它的API是Apple专用的.
It turns out there is some power management going on that can take down the 3G network interface. The API to bring it back up is Apple private.
在使用普通香草BSD插槽时，这似乎最常见.
This seems to crop up most often when using plain vanilla BSD sockets.
Apple在CFSocketStream内添加了一些代码，以检查流量并在流量仍在流动的情况下保持网络接口正常运行.如果一分钟左右没有看到任何流量，则可以拆除网络接口，并关闭天线以节省功率.如果您通过CFSocketStream发送流量，则应该重新发送流量.对于UDP，您可能必须打开CFSocketStream并偶尔发送一些流量，以保持接口正常运行.
Apple has added some code inside of CFSocketStream to check for traffic and keep the network interface up if traffic is still flowing. If it sees no traffic for a minute or so the network interface can be torn down and the antenna turned off to save power. If you send traffic across the CFSocketStream it should come back up. In the case of UDP, you'll probably have to open a CFSocketStream and send some traffic occasionally in order to keep the interface up.
