Undefined symbols for architecture i386:
"_OBJC_CLASS_$_Reachability", referenced from:
objc-class-ref in FirstViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我查看了 FirstViewController、reachability.h 和reachability.m——它的定义很明确!我什至添加了 SystemConfiguration.Framework,以及 Reachability.m 在编译列表中。
有任何想法吗?我快疯了!附图片。
