[iOS]关于更新ShareSDK报Undefined symb

因项目要求更新SDK到最新版本，昨天跟新SDK到最新版本之后编译运行项目只有报错

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_PayResp", referenced from:
      objc-class-ref in PublicPayManager.o
  "_OBJC_CLASS_$_PayReq", referenced from:
      objc-class-ref in PublicPayManager.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

或者是

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_PayResp", referenced from:
      objc-class-ref in PublicPayManager.o
  "_OBJC_CLASS_$_PayReq", referenced from:
      objc-class-ref in PublicPayManager.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

之后查找了各种方法还是无法解决该问题，在这两种错之间徘徊，最后查找了原因是更新ShareSDK的问题。
因项目本身有微信支付和支付宝支付，自己已经单独集成了一个关于微信APP支付的SDK，而ShareSDK从4.0.4之后更新cocopods的Podfile 文件中的地址
ShareSDK cocopods集成 更换成了：

pod 'mob_sharesdk'
 
# UI模块(非必须，需要用到ShareSDK提供的分享菜单栏和分享编辑页面需要以下1行)
pod 'mob_sharesdk/ShareSDKUI'
 
# 平台SDK模块(对照一下平台，需要的加上。如果只需要QQ、微信、新浪微博，只需要以下3行)
pod 'mob_sharesdk/ShareSDKPlatforms/QQ'
pod 'mob_sharesdk/ShareSDKPlatforms/SinaWeibo'
pod 'mob_sharesdk/ShareSDKPlatforms/WeChat'   //（微信sdk不带支付的命令）
# pod 'mob_sharesdk/ShareSDKPlatforms/WeChatFull' //（微信sdk带支付的命令，和上面不带支付的不能共存，只能选择一个）
 
# ShareSDKPlatforms模块其他平台，按需添加
# 如果需要的平台没有对应的平台语句，有2种情况——1、不需要添加这个平台的语句，如Twitter就是这个情况。2、ShareSDK暂时不支持此平台。
pod 'mob_sharesdk/ShareSDKPlatforms/RenRen'
pod 'mob_sharesdk/ShareSDKPlatforms/AliPaySocial'
pod 'mob_sharesdk/ShareSDKPlatforms/Kakao'
pod 'mob_sharesdk/ShareSDKPlatforms/Yixin'
pod 'mob_sharesdk/ShareSDKPlatforms/Facebook'
pod 'mob_sharesdk/ShareSDKPlatforms/Copy'
pod 'mob_sharesdk/ShareSDKPlatforms/Evernote'
pod 'mob_sharesdk/ShareSDKPlatforms/GooglePlus'
pod 'mob_sharesdk/ShareSDKPlatforms/Instagram'
pod 'mob_sharesdk/ShareSDKPlatforms/Instapaper'
pod 'mob_sharesdk/ShareSDKPlatforms/Line'
pod 'mob_sharesdk/ShareSDKPlatforms/Mail'
pod 'mob_sharesdk/ShareSDKPlatforms/SMS'
pod 'mob_sharesdk/ShareSDKPlatforms/WhatsApp'
pod 'mob_sharesdk/ShareSDKPlatforms/MeiPai'
pod 'mob_sharesdk/ShareSDKPlatforms/DingTalk'
pod 'mob_sharesdk/ShareSDKPlatforms/YouTube'
pod 'mob_sharesdk/ShareSDKPlatforms/Twitter'
pod 'mob_sharesdk/ShareSDKPlatforms/Dropbox'
 
# 使用配置文件分享模块（非必需）
pod 'mob_sharesdk/ShareSDKConfigFile'
 
# 扩展模块（在调用可以弹出我们UI分享方法的时候是必需的）
pod 'mob_sharesdk/ShareSDKExtension'

关于微信的SDK他给了两个一个是带有支付的SDK一个是没有带有支付的SDK无论集成那个都和自己集成的微信支付的SDK有冲突，造成错误。后来问询了Mob的技术支持才知道要是用他们的微信分享的SDK，就不能再自己集成微信SDK，只能是删除自己集成的微信支付SDK了。

解决办法：更新ShareSDK4.0.4之后版本时，并且本身项目有微信支付；直接导入ShareSDK带有支付的微信SDK，删除自己本身项目集成的SDK。
