library not found for -lWeChatSD

library not found for -lWeChatSDK

**遇到错误的原因：项目上传到SVN并打了分支，想着以后规范一点，不要一直在主干上改来改去（虽然是自己一个人管理的）
上传后check out到本地发现这种错误。
1. library not found for -lSocialQQ （第一次错误）
经过尝试重新pod install后解决（）
2. library not found for -lssl （第二次错误）
经过尝试把包含ssl的文件夹整个替换一遍解决
3. library not found for -lWeChatSDK （第三次错误）
同样替换包含WeChatSDK的文件夹

可以看到和融云有关，项目中用cocoapods集成了融云，1.先在podfile中删除融云，2.重新pod 'RongCloudIM/IMKit','~> 2.9.16' ; 3.pod install 解决
5. ld: 5 duplicate symbols for architecture x86_64
这个原因是在解决上面4个问题的过程中在Link Binary With Libraries中加入了融云的fromwork,属于重复添加，删除掉就好了，参考解决duplicate symbols for architecture x86_64编译错误问题
6. ld: library not found for -lopencore-amrnb
项目中搜索opencore-amrnb，看到：

opencore-amrnb.png
猜测和cocoapods有关（不太明白这是什么opencore-amrnb），于是编辑podfile文件，先删除所有第三方，再重新pod install解决

终于搞定了

后面估计还会有问题。。。
