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
