升级xcode9之后，pod update然后运行遇到以下问题： /xxxx/Pods/UMengSocial/Umeng_SDK_Social_iOS_ARM64_5.0/UMSocial_Sdk_5.0/SocialSDKXib/UMSCommentDetailController.xib: warning: Internationalization is not available when compiling for targets before iOS 6.0 Command /bin/sh failed with exit code 1
解决方案： 找到pods-> UMengSocial->Resources-所以的xib改成你自己项目支持的最低的ios系统版本
