为什么我的崩溃报告没有象征意义？ [英] Why are my crash reports not symbolicated?
问题描述
我正在使用Xcode 4.3.1。崩溃发生在我的设备上，所以我连接它并打开管理器，转到我的设备日志，找到崩溃报告，这里是它的内容：
I'm using Xcode 4.3.1. The crash happened on my device, so I connect it and open up Organizer, go to my device logs, find the crash report, and here's what it reads:
Exception Type: EXC_CRASH (SIGABRT)

我以为Xcode会自动为我设置崩溃报告？为什么我没有获得任何行号或方法？为什么我的异常代码为0x00000000？
I thought Xcode handles symbolicating the crash reports for me automatically? Why am I not getting any line numbers or methods? And why are my exception codes 0x00000000?
我试过此处找到的方法，但是当我键入任何内存地址时，输出就是相同的内存地址。这是我可以从崩溃日志中获取的最多信息，还是这里有问题？
I tried the method found here, but when I type in any of the memory addresses, the output is just that same memory address. Is this the most information I can get out of the crash logs, or is something wrong here?
推荐答案
表示崩溃报告你需要那个精确构建的dSYM包。我猜这是一个未归档的调试版本，因此下次构建应用程序时dSYM也会被覆盖。这就是组织者无法完全表示崩溃报告的原因。
To symbolicate the crash report you need the dSYM package of that exact build. I guess this was a debug build that wasn't archived, so the dSYM also got overwritten the next time you build the app. This is why the organizer couldn't fully symbolicate the crash report.
您提到的方法只有在二进制文件没有剥离符号时才有效，即使这样也不会报告行号！因此，不要将其用于app二进制文件，而是将其与dSYM一起使用。也许你很幸运，新的dSYM仍然有一些有用的信息。
The method you mentioned only works if the binary does not have symbols stripped, and even then it would not report the line numbers! So instead of using it against the app binary, rather use it with the dSYM. Maybe you are lucky and the new dSYM still has some helpful information.
atos -arch armv7 -o'appname.app.dSYM'0x0015b4a7
崩溃本身可以将NSDictionary值设置为例如没有钥匙。
The crash itself could to be setting a NSDictionary value to e.g. a nil key.
