9、微信分享SDK 使用报错

1、错误：微信分享SDK 使用报错

Undefined symbols for architecture armv7:

  "_OBJC_CLASS_$_CTTelephonyNetworkInfo", referenced from:

      objc-class-ref in libWeChatSDK.a(MTAHelper.o)

ld: symbol(s) not found for architecture armv7

clang: error: linker command failed with exit code 1 (use -v to see invocation)

2、解决：导入 CoreTelephony.framework 试试
