objective-c - 理解 Objective-C 的 throw 调用栈

Question

一个用户刚刚向我提交了一个错误报告，说我的应用程序崩溃了。用户还附加了一个 throw 调用堆栈。

似乎导致问题的部分是:

       3   My App                0x000000010d005483 My App + 17539

有没有办法翻译那个地址和/或 + 17539到我的代码中的行号？

请记住，我无法在我的机器上重现该错误，因此我不能仅在 Debug模式下构建它。

看看这个Tech note来自苹果。

... This trace is similar to what you would see when stopping execution in the debugger, except that you are not given the method or function names, known as symbols. Instead, you have hexadecimal addresses and executable code - your application or system frameworks - to which they refer. You need to map these addresses to symbols. Unlike crash logs from Mac OS X, iPhone OS logs do not contain symbol information when they're written out. You have to symbolicate iPhone OS logs before you can analyze them.
