应用程序可以通过多种方式捕获崩溃。在大多数类型中，IDE 提供的信息已经足够了。 (Xcode & iOS/OS X 开发) 但是有一些崩溃报告为我们提供了崩溃的线程及其堆栈跟踪(像往常一样)，但其中没有一帧指向来 self 们应用程序的任何调用!那里涉及本地库。
谁能分享他/她自己修复此类错误的经验以及现有的崩溃报告？
非常感谢!
更新:
我熟悉以下文档:Crash Report (TN2123) , 翻看了 function calling conventions ，开始Mac OS X Debugging Magic (TN2124) 。
但还没有成功。
UPD2，堆栈跟踪:

我注意到异常代码中的地址等于cr2寄存器中的地址，但与技术说明中所写的rip中的地址不同。
最佳答案
您可以使用 lldb 或 gdb 从 Xcode 的 调试控制台调试代码。在崩溃时，这些命令可能有助于在运行时获取有关对象状态的信息，以继续解决问题的根本原因。有关您可以使用的命令列表，请参阅 http://lldb.llvm.org/lldb-gdb.html

您还可以启用Zombie 以获取与崩溃相关的更多信息
NSZombie 是一个 Cocoa 技巧，可以将任何要被释放 的对象变成一个 NSZombie 实例。无论如何你都会崩溃，但是不是 Xcode 只是提示你试图访问错误的内存地址，你会得到一些更好的东西，像这样:
2011-02-25 01:27:57.063 WordPress[10496:207] *** -[CFString isEqualToString:]: message sent to deallocated instance 0xcf1b0c0
不多，但至少你知道有罪的对象是一个字符串。

关于ios - Objective C，在堆栈跟踪中不涉及我的应用程序时处理崩溃报告，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30593927/
