Question

我正在为iOS开发SDK，我在代码中添加了一些assert（）来帮助我捕获bug。它在使用模拟器时工作得很好，但是如果我在设备上构建我的应用程序（Debug-iphoneos），从我的mac上拔下它并将其留待测试，我从断言失败中获得的崩溃日志是不可能理解的。来自基本零断言失败的实际样本：

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

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

Answer 1

解决了这篇文章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
