我正在检查一些 Xcode 崩溃日志，我想知道每行末尾的数字意味着：

它们是机器码偏移量

例如在这张图片中，

  • libsystem_kernel.dylib mach_msg的机器码从地址开始0x18474f054。
  • libsystem_kernel.dylib mach_msg + 68，如您所见，这是mach_msg_trap被调用的地方，而mach_msg_trap's addrss 是0x18474f21c，
  • libsystem_kernel.dylib mach_msg + 72是断点停止的地方，等于0x18474f054 + 0x72

在此处输入图像描述

您的崩溃日志没有符号化。如果你象征它，它应该给你更容易解释的信息。

这是一个讨论这个的文件：
