通过Organizer找到.xcarchive文件(右键Show In Finder),用终端打开，可以看到目录下有三个文件(夹)

Info.plist Products dSYMs

进入 dSYMs/xxx.app.dSYM/Contents/Resources/DWARF 目录下的文件就是经过编译生成的二进制文件

要看CPU Type 有可能是armv7s

执行 atos -arch armv7/armv7s -o kddemo 0x589391可以看到

-[ChatBubbleView setupDirectMessageDetailsView] (in kddemo) (ChatBubbleView.m:149)

以此具体追踪问题
