Post the crash log. (the header and crashed thread, at least - don't need the long list of binaries)If it is symbolicated, it should contain the source file and line number if any of your code is involved in the crash. If it's not symbolicated, drag it into the Device Logs view in Xcode's Devices window when you have a device connected. Xcode should then symbolicate it.
