ios - 为 Debug-iphoneos 构建时如何调试断言

Question

我正在为 iOS 开发一个 SDK，我在代码中添加了一些 assert() 来帮助我捕获错误。使用模拟器时它工作得很好，但如果我在设备上构建我的应用程序(调试-iphoneos)，将其从我的 Mac 上拔下并留作测试，我从断言失败中获得的崩溃日志将无法理解。来自基本 nil 断言失败的真实示例:

Exception Type:  EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x00000000e7ffdefe
Triggered by Thread:  0

Filtered syslog:
None found

我有机会从崩溃日志中获取更多信息吗？我试过atos -arch armv7 -o MyApp.app/MyApp 0x24f000没有任何成功(返回0x24f000)

Answer 1

通过这篇文章解决了Atos does not symbolicate system frameworks/libraries properly

这里我必须从 .app 中提取我的框架并执行

xcrun atos -arch armv7 -o  MyFramework.framework/MyFramework -l 0x24f000 0x002ddfec
