崩溃日志 求分析

Question

1.

2.

这2个我该怎么定位,拿不到错误的地方

Answer 1

还好找到个测试机, 看看crash log, Xcode -> window -> Devices, 选择设备, View Devices logs. 可以看到该设备下App的错误日志. (好像跑题了!)
如何将手机中的错误日志导入到Mac电脑上

---

解读crash log: (以我本机为例)

1.进入Archives

$cd /Users/chris/Library/Developer/Xcode/Archives/

2.选择xcarchive, 并进入到dSYMs

$cd 2017-xx-xx/YourProject 2017-xx-xx .xcarchive/dSYMs

3.查看设备的UUID及错误日志路径

$dwarfdump --uuid YourProject.dSYM/

4.用lookup查看崩溃地址(我是瞎写的地址^_^!)

$dwarfdump --arch=armv7 --lookup 0x95277 /Users/yourMacName/Library/Developer/Xcode/Archives/2017-xx-xx/YourProject\ 2017-xx-xx.xcarchive/dSYMs/YourProject.app.dSYM/Contents/Resources/DWARF/YourProject

5.AT_decl_file是crash文件位置, AT_name是调用哪个方法出的错.
6.实测
