我正在尝试在我的项目中使用可达性。我添加了 Reachability.h 和 Reachability.m 文件。但是在构建项目之后 xCode 向我显示了奇怪的错误:
Undefined symbols for architecture i386:

+[Reachability reachabilityWithHostname:] in Reachability.o

-[Reachability isConnectionOnDemand] in Reachability.o
-[Reachability isInterventionRequired] in Reachability.o

我该如何解决这个问题？
最佳答案
可能您忘记将 SystemConfiguration.framework 添加到您的项目中。如果您不知道如何添加框架，请查看此 SO question .
