当我按照教程：http://http:/https://www.sinch.com/tutorials/minichat-ios-messaging-app/#project%20setup并将Xcode更新为6.3.1时，我遇到链接器错误，我很难修复它。
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_SINOutgoingMessage", referenced from:
objc-class-ref in AppDelegate.o
"_OBJC_CLASS_$_Sinch", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我使用cocoapods安装Sinch并使用armv7，armv7s作为架构。
您的评论和建议非常感谢。
