SCNetworkReachability编译错误

我试图编译Ercia Sadun的示例代码here，但这个错误想出了：SCNetworkReachability编译错误

......即使在我加入systemConfiguration.framework，它报道了同样的错误。它为什么这样做，我该如何使它工作？

您添加了哪个SystemConfiguration.framework？第一行明确提出

警告：/Users/interdev/iphone source code/Web Browser/Classes/SystemConfiguration.framework/SystemConfiguration，在文件

缺少必需i386硬件架构，但你应该添加SDK之一，在/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks。

该框架应该通过项目右键菜单中的“Add Existing Framework ...”添加。

@user如果你正在编译模拟器，路径应该是'/ Dev/Pl/''** ** iPhoneSimulator.platform''/开发/软件开发工具包/''** ** iPhoneSimulator3.1.sdk''/系统/ LIB/FR/SysConf.fr'。选择SysConf框架，查看信息，然后选择“相对于当前SDK”。 – kennytm 2010-03-09 13:36:09

我试着添加你说的框架，但是当我通过点击'Getinfo'来检查时，它仍然指向 /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.sdk/System/Library/Frameworks /SystemConfiguration.framework 我检查了Erica Sadun的项目，它现在运行良好。但如果我将他们的源代码添加到我的项目中，错误仍然存在。 – arachide 2010-03-09 15:05:09
