第一步:在任意目录创建一个目录,用来调试crash,我这里创建一个crash目录
第二步:将之前Archive的文件copy到crash目录里面
其中包括两个文件.app和.app.dSYM
如果找不到的话可以按照下面的步骤进行
先到Organizer
1,找到提交那个时刻的Archive文件,选中,show in Finder
2,然后到达这里,然后再选中红色区域,会出现3中所示的提示
3,ok显示包内容,然后自己找找吧,肯定会有的
copy就好了
第三步:将symbolicatecrash工具copy到crash目录
找不到这个文件可以去
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources
这里看看,应该就会有了。
第四步:将要调试的crash文件copy到crash目录
这个crash文件,这里是来自苹果官方的,其实有时候也是来自其他的用户的电脑上的。
第五步:通过命令进行测试
打开终端,转到crash目录
执行如下命令:
./symbolicatecrash ./2013-08-16-035933_DLiPad.crash ./appname.app.dSYM > symbol.crash cat ./symbol.crash
结果如下:

如果有多个crash文件的话,可以重复操作一遍就好了。
