How to interpret a crashlog with no references to a specific class

Today my app crashed and generated this crashlog. The crashlog does not mention any classes in my project and to开发者_如何学C me it seems almost impossible to tackle this issue.

Any ideas how to approach this problem? Thanks for your help!

There's a tool included in Apple's Developer's tools called symbolicatecrash. With it you can symbolicate crash reports, but note that you'll need the associated .dsym file of your build Check this post to see a tutorial using it.

This is how I ran the symbolitecrash binary.

Find the binary symbolitecrash

locate symbolitecrash

Optional: You may add a convenience link to /usr/bin

sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash /usr/bin/symbolicatecrash

Copy the crash log to the Debug-iphoneos folder and go to the project

cp ~/Desktop/TheCrash.crash ~/Myproject/build/Debug-iphoneos
cd ~/MyProject/build/Debug-iphoneos

Run the crash log symbolicater

symbolicatecrash TheCrash.crash MyProject.app.dSYM > ReportWithSymbols.crash

The result
