symbolicatecrash with XCode 4.2 not symbolicating system symbols
提问by Mike Fullerton
This is a very weird problem. I think I must be doing something wrong, but I don't know what it is. I've been using symbolicatecrash for several years with no problems. The issue I'm seeing is that symbolicatecrash is not showing symbols for the system libraries, but it IS showing symbols for my application. I've tried everything I can think of to resolve this with no luck.
这是一个非常奇怪的问题。我想我一定是做错了什么，但我不知道那是什么。我已经使用symbolicatecrash 好几年了，没有任何问题。我看到的问题是symbolicatecrash 没有显示系统库的符号，但它显示了我的应用程序的符号。我已经尝试了所有我能想到的方法来解决这个问题，但没有运气。
Note that I'm getting the same results on three different machines, 2 Lion, 1 Snow Leopard.
请注意，我在三台不同的机器上得到了相同的结果，2 台 Lion，1 台雪豹。
Example command line: /Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash /Users/mike/Downloads/mycrash-iPad.crash
示例命令行：/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash /Users/mike/Downloads/mycrash-iPad.crash
Note also that I get the same results when I drag the file into the logs section of the XCode 4.2 logs organizer window and wait for XCode to symbolicate the file.
另请注意，当我将文件拖到 XCode 4.2 日志管理器窗口的日志部分并等待 XCode 对文件进行符号化时，我得到了相同的结果。
Here's an example of a crash in my code with the partially symbolicated symbols:
这是我的代码中带有部分符号化符号的崩溃示例：

I've run the symbolicate crash command with -v and it's finding the app.dSym files okay, it just doesn't seem to be finding the library symfiles which seems to be the opposite problem most people are having. Facepalm.
我已经用 -v 运行了符号崩溃命令，它找到了 app.dSym 文件，但似乎没有找到库符号文件，这似乎是大多数人遇到的相反问题。面掌。
For example, here's the output from a -v run for the CoreFoundation lib:
例如，这是 CoreFoundation 库的 -v 运行的输出：

I really am at a loss to figure out what to try next.
我真的不知道下一步该尝试什么。
Does anyone have any ideas? I'm fresh out. Your help will be much appreciated!

More info, now I'm getting an error in the symbolicatecrash output.

The following solved the problem for me:
以下为我解决了这个问题：
- Delete the folder ~/Library/Developer/Xcode/iOS DeviceSupport/5.0.1 (9A405)
- Reattach your iOS device and it will automatically import the correct symbols.
- 删除文件夹 ~/Library/Developer/Xcode/iOS DeviceSupport/5.0.1 (9A405)
- 重新连接您的 iOS 设备，它会自动导入正确的符号。
After that the crash reports could be symbolicated correctly. (to re-symbolicate a crash report, open the Organizer, click on 'Reveal in Finder' and delete the symbolicated version)
之后，崩溃报告可以正确符号化。（要重新符号化崩溃报告，请打开管理器，单击“在 Finder 中显示”并删除符号化版本）

It looks like this is an acknowledged bug with Xcode 4.2 and iOS 5:
看起来这是 Xcode 4.2 和 iOS 5 的公认错误：

A new Xcode beta was released for Lion yesterday, does that work for you? I can't try it myself because it's not available for Snow Leopard yet.
昨天为 Lion 发布了新的 Xcode 测试版，这对您有用吗？我无法自己尝试，因为它尚不可用于 Snow Leopard。
