iOS审核崩溃及设置IPv6,日志分析
当后台审核遇到崩溃被拒绝的时候:
1:查看拒绝原因
Guideline 2.1 - Performance
Your app crashed on iPad or iPhone running iOS 11.2.5 connected to an IPv6 network during our review.
We have attached detailed crash logs to help troubleshoot this issue.
Next Steps
To resolve this issue, please revise your app and test it on a device to ensure that it runs as expected.
2:下载崩溃日志
attachmentlog2018.crash
3:分析拒绝原因
在我们审核期间，您的应用在IPv6网络上运行iOS 11.2.5的iPad或iPhone上崩溃。
拒绝原因有两个地方: 崩溃 和 IPv6
关于崩溃,后面会分析日志
关于IPv6,有两种关键词的情况:
1:是IPv6 //意思是出现bug的时候网络是IPv6下,可能IPv4下也会
2:是IPv6only //意思是出现bug的时候网络只有IPv6下会
上面第一种情况需要同时测试APP性能和IPv6下运行情况
上面第二种情况优先测试IPv6下运行情况
4: 分析崩溃日志
设备:MacPro 和 iPhone
准备工作:
在电脑上创建文件夹crash
将崩溃日志文件attachmentlog2018.crash放到文件夹crash里
打开Xcode代码,Window -> Organizer
Organizer
找到对应的审核版本(根据版本号和build号),右键进入文件夹:

右键进入包内容:

将下面两个文件也copy到crash文件夹里:
app.dSYM
APP
打开Finder,前往文件夹:复制symbolicatecrash文件
/应用程序/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash
开始执行命令生成log文件:
cd /Users/niexiaobo/Downloads/Crach
./symbolicatecrash ./.crash ./.dSYM > crash20180308.log
如果报错了,执行下面命令:
export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer
再执行:
./symbolicatecrash ./.crash ./.dSYM > crash20180308.log
成功的话文件夹里有个crash20180308.log
[ 也许你可以选择: 比如使用QuincyKit, Crashlytics, Flurry等来进行管理 ]
打开文件crash20180308.log,分析log:
log开头是一段设备信息:

接着是:[UITableViewAccessibility _accessibilitySupplementaryHeaderViews],可能和tableview加载有关.
然后分析原因并处理.
5: 链接IPv6进行测试
大家可以网上搜索教程,在此我用MacPro笔记本和iPhone各一台测试
打开电脑的偏好设置
进入共享
共享
选择互联网共享按钮时,弹出提示框,开启共享,最后如下图:
互联网共享
把手机或者ipad设备设置飞行模式,再通过USB链接电脑,接着运行APP就可以了.
注意:
关于IPv6问题,有人是通过VPN把域名映射到美国,也可能是没有写域名,直接写了ip地址,等等
上面设置只是国内服务器,而审核人员是美国加州的外网IPv6下测试,需要链接vpn设置.
