Xcode報錯: 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)
工程中導入CoreTelephony.framework 庫即可
