为什么这个iOS应用程序无法访问网络？ [英] Why can't this iOS app access the network?

问题描述

我的（Unity）应用程序抱怨我的iPod没有网络连接，而设备具有完整的Wi-Fi连接（所有其他应用程序，包括Safari）都证明了这一点。

My (Unity) app complains that the my iPod does not have network connectivity while the device has full wi-fi connectivity (as evidenced by every other app, including Safari).

这不仅仅是一个API点 - 所有这些（Facebook，StoreKit等）声称网络不可用。

This isn't just one API point - all of them (Facebook, StoreKit, etc) claim that the network is not available.

此消息定期从我的应用程序发送到控制台：

This message is periodically sent to the console from my app:

<错误>：初始化期间无法成功更新网络信息。

可能（我认为）来自 CoreTelephony 。

which may (I think) be coming from CoreTelephony.

知道造成这种情况的原因是什么吗？我在调试和adhoc构建中得到它。我没有在设备上激活任何限制（来自设置）。

Any idea what is causing this? I get it in debug and adhoc builds. I do not have any Restrictions (from Settings) active on the device.

该设备为iOS 6，基本sdk为iOS 5.

The device is iOS 6 and the base sdk is iOS 5.

推荐答案

初始化期间无法成功更新网络信息。每次在没有SIM卡的设备（iPod touch或没有3G的iPad）中初始化CTTelephonyNetworkInfo时，都会显示日志。

The "Could not successfully update network info during initialization." log is shown every time you initialize the CTTelephonyNetworkInfo in a device without SIM card, (iPod touch or iPad without 3G).

如果它非常烦人，你只需初始化一次并对该实例进行网络检查。

If it's very annoying, you can just initialize it once and do your network checks against that instance.
