Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1
提问by Abhinav
I am getting following error when I am running my application on iPod touch (version 4.2.1). My app crashes after a point:
当我在 iPod touch（4.2.1 版）上运行我的应用程序时出现以下错误。我的应用程序在某一点后崩溃：
Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).
Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).
My XCODE version is 3.2.6 with IOS 4.3 and my deployment target version is 4.2.
我的 XCODE 版本是 3.2.6 和 IOS 4.3，我的部署目标版本是 4.2。
Any reason why this is so happening?
为什么会发生这种情况？

Sometimes I have similar problems, and what works for me is Cleanand Buildthe target again (without any changes in code!). Strange, but sometimes I had to do it more than once.
有时我会遇到类似的问题，对我有用的是清理并再次构建目标（无需更改代码！）。奇怪，但有时我不得不做不止一次。

Just delete that folder (/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1), connect your device again, go to the XCode Organizer and it will ask you to collect the symbols from the device. After a couple minutes it will be done collecting and processing the symbols off the device, and you should be good to go.
只需删除该文件夹 (/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1)，再次连接您的设备，转到 XCode Organizer，它会要求您从设备中收集符号。几分钟后，它将完成收集和处理设备上的符号，您应该可以开始了。

For some reason just got this in XCODE 4.2. Had to go to
出于某种原因，刚刚在 XCODE 4.2 中得到了这个。不得不去
TARGET / BUILD SETTINGS / ALL / SEARCH PATHS / Library Search Paths
目标/构建设置/所有/搜索路径/库搜索路径
And remove the line that somehow had similar entry in the line. Removed it and all is ok
并删除该行中以某种方式具有类似条目的行。删除它，一切正常
