Question

链接错误：

ld: duplicate symbol _OBJC_METACLASS_$_Reachability in /Users/jmf/Documents/iOS Development/jmf_Client/jmf/jmf/ww_libs/libmfcbroem_ios.a(Reachability.o) and /Users/tpf/Library/Developer/Xcode/DerivedData/jmf-erlknghfcpoomnfanzovahfacgpv/Build/Intermediates/jmf.build/Debug-iphoneos/jmf.build/Objects-normal/armv7/Reachability.o for architecture armv7

如果我只是删除h / m文件（以及相关的import指令），希望只使用libmfcbroem_ios.a中的Reachability ...链接器抛出这个：

Undefined symbols for architecture armv7:
  "_kReachabilityChangedNotification", referenced from:
      -[MKNetworkEngine initWithHostName:customHeaderFields:] in MKNetworkEngine.o
      -[MKNetworkEngine dealloc] in MKNetworkEngine.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

如何告诉链接器使用“a”文件中的Reachability？

（免责声明，我刚刚开始使用ObjC / iOS）

感谢您的帮助......
