1. stack trace 一般长这样:

  1. 需要用到的有提交该版本时的 dSYM 以及 atos

  2. 命令格式为 atos -arch <arch> -o app.dSYM/Contents/Resources/DWARF/app -l <load address> <stack address 1> <stack address 2> ...

  3. 其中 arch 可由 dwarfdump -u app.dSYM 得到。

  4. load address 为 stack address - shift,本例中为 0x000000010412db0c - 72460 = 0x10411c000,计算一次即可。

  5. 运行 3 中命令即可得到结果如:

SleepViewController.backTap(_:) (in Sky) (SleepViewController.swift:164)
implicit closure #1 in SleepViewController.didTapApply(withDuration:) (in Sky) (<compiler-generated>:0)
protocol witness for Message.traverse<A>(visitor:) in conformance SkyGetMusicFromFavoriteRequest (in Sky) + 8
