在尝试接入微信第三方时遇到了编译错误，包括未找到的符号如`CTTelephonyNetworkInfo`，需要导入`CoreTelephony.framework`。另外，也存在`operator delete[]`和`operator new[]`的符号问题，解决方法是导入`libc++.tbd`库。通过正确导入这两个框架，可以解决x86_64架构的链接错误。
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_CTTelephonyNetworkInfo", referenced from:
objc-class-ref in libWeChatSDK.a(MTAHelper.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
以上问题需要导入：：CoreTelephony.framework
Undefined symbols for architecture x86_64:
"operator delete[](void*)", referenced from:
+[WeChatApiUtil EncodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
+[WeChatApiUtil NsDataEncodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
+[WeChatApiUtil DecodeWithBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
+[WeChatApiUtil DecodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
"operator new[](unsigned long)", referenced from:
+[WeChatApiUtil EncodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
+[WeChatApiUtil NsDataEncodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
+[WeChatApiUtil DecodeWithBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
+[WeChatApiUtil DecodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
这个需要导入 libc++.tbd (xcode里面)
