我试图编译ercia sadun的示例代码 here ,但出现此错误:

…即使在我添加了systemconfiguration.framework之后,它也报告了相同的错误。为什么要这样做,我怎样才能让它工作?

您添加了哪个systemconfiguration.framework?第一行写得很清楚

警告:在 /Users/interdev/iphone source code/Web Browser/Classes/SystemConfiguration.framework/SystemConfiguration ,文件中缺少所需的体系结构i386

但是您应该在 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks .

框架应该通过项目右键单击菜单中的“添加现有框架…”来添加。
