为i386硬件架构未定义的符号：“_SCNetworkReachabilitySetCallback”

我用xcode4，在openglES项目我添加了一些代码，在应用程序内购买从教程： http://www.raywenderlich.com/2797/introduction-to-in-app-purchases 为i386硬件架构未定义的符号：“_SCNetworkReachabilitySetCallback”

我已经添加SystemConfiguration.framework但发生这样的错误：

如果我删除框架引用的错误是一样的。再次添加没有任何反应... in -Xlinker 2 -framework基础框架UIKit [...]我应该看到“-framework SystemConfiguration”对吗？为什么不在那里？有没有人有想法？

从以项目拉起框架>建立phases->链接二进制与图书馆成为首个框架，我有这个误差修改：

SystemConfiguration是存在的，错误仍然存在... 它会是什么？谢谢

找到了！我已经将SystemConfiguration.framework复制到我的项目文件夹（当我从xcode添加时检查框）。删除我的项目中的文件夹现在编译好了

我想指出我也有类似的问题。

我将一些文件复制到xcode中，并意外地选择了“ProjectTests”而不是项目。只需删除这些文件并将它们重新添加到项目中，确保选择了主项目（而不是单元测试）

从回购更新后，我遇到了同样的问题。

我工作的解决方案是从项目中删除所有类的引用并再次添加它们。问题在于有很大的可能性搞砸了回购同步。

你是怎么做到的？ – quantumpotato

我也有同样的问题。我直接添加了一些框架，拖放它们。

要解决这个问题，我删除了所有的人，并增加他们通过菜单目标>构建阶段，然后再通过链接二进制与图书馆添加了所有需要的框架。

之后，你的代码应该再次正常工作。

+1谢谢你，它的作品....！ – Dinesh

从构建阶段我的项目编译孔加入SystemConfiguration.framework后...

有一个有趣的...！

谢谢......对我有用！ –

这是最正确的答案 –

谢谢！这也适用于我！ – ChemDev

很简单。

scnetworkreachability回调被标记为这意味着一些图书馆或框架文件未定义的符号丢失

前缀SC意味着系统配置

点击项目名称选择摘要在右侧
cl ICK 链接的二进制文件和框架
点击再加上它，那么你可以看到一个钻下来的框架和libaries看藏品有没有什么所谓的 systemConfigurationframework
选择，然后按ok
现在构建和运行问题是解决

当我使用AFNetworking，收到这些错误进口3个框架

CFNetwork.framework 
Security.framework 
SystemConfiguration.framework

所有错误都将消失后..享受！

如上所述，导入以下3个框架后，它就可以工作！

CFNetwork.framework 
    Security.framework 
    SystemConfiguration.framework

非常感谢！
