我们需要使用 Sina Weibo SDK 的某些特定版本，因此创建了一个 Pod 来管理版本。

崩溃：-[NSConcreteMutableData wbsdk_base64EncodedString]： unrecognized selector

解决方案有二：1、添加-ObjC或-all_load配置；2、如果由于-ObjC或-all_load引起较多冲突，可以尝试使用 -force_load $(PODS_ROOT)/SinaWeiboSDKV/libWeiboSDK/libWeiboSDK.a

SinaWeibo HTTPS Error：[] nw_coretls_read_one_record tls_handshake_process: [-9801] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9801)
