\n– Sync your iPhone to iTunes.
\n– Find the crash logs on your computer.\u00a0 Here is where they\u2019re located;<\/p>\n
- \n
- Mac OS X\u00a0<\/strong>:\u00a0
~\/Library\/Logs\/CrashReporter\/MobileDevice\/<DEVICE_NAME><\/code><\/li>\n- Windows XP<\/strong>:\u00a0
C:\\Documents and Settings\\<USERNAME>\\Application Data\\Apple computer\\Logs\\CrashReporter\/<DEVICE_NAME><\/code><\/li>\n- Windows Vista\\Windows 7:<\/strong><\/strong>:\u00a0
C:\\Users\\<USERNAME>\\AppData\\Roaming\\Apple computer\\Logs\\CrashReporter\/MobileDevice\/<DEVICE_NAME><\/code><\/li>\n<\/ul>\nThe log file names start with application name and have the extension \u201ccrash\u201d; The logs themselves are just text files, so you can open them in your text editor and cut&paste, or (preferably) attach them to an email to sent to developers;<\/p>\n
A typical crash report looks like this (if you open it in text editor)<\/p>\n

<\/a><\/p>\nHere <application name> <\/em> is the name of your application that crashed;<\/p>\n
Steps to symbolicate crash Report; (Developer End)<\/strong><\/p>\n
Symbolication is a process of decoding the crash report to find out the exact class name and method name that creates problem;<\/p>\n
You can notice in above image that there were different thread that were running parallel and the 2nd line tells us which thread\u00a0crashed; After decoding the crash report , you will go through that thread entries to find out your classes\/method;<\/p>\n
There is a script available in your mac machine for symbolication process; You can find that script at<\/p>\n
\/Developer\/Platforms\/iPhoneOS.platform\/Developer\/Library\/Xcode\/Plug-ins\/iPhoneRemoteDevice.xcodeplugin\/Contents\/Resources\/symbolicatecrash \/usr\/local\/bin\/<\/em><\/strong><\/p>\n
If you unable to find it, I have upload it at following url; unzip it and put at your preferable location;<\/p>\n
http:\/\/dl.dropbox.com\/u\/18976202\/symbolicatecrash.zip<\/a><\/p>\n
Note: IT IS VERY IMPORTANT THAT YOU SAVE YOUR BINARY FILE (APP FILE) ALONG WITH dSYM FILE WHEN YOU SHIP YOUR APPLICATION; WITHOUT HAVING THESE FILES YOU ARE NOT ABLE TO DECODE THE CRASH REPORTS;<\/strong><\/p>\n
Its time to start symbolication;<\/strong><\/p>\n
– Copy your crash report, .app file and\u00a0.dSYM file along with downloaded scrip (Put everything in one directory)
\n– Open your terminal and move to the directory where you copy download script;
\n– execute following commad<\/p>\n.\/symbolicatecrash -A -v <crashReportName> <dSYM file name><\/strong><\/p>\n
for example if your application name is myGame<\/em>, then your binary file name would be myGame.app<\/em> and your dSYM file would be myGame.app.dSYM.<\/em><\/p>\n
The format of crash report name is as follow
\napplicationName_yyyy-mm-dd-hhmmss_deviceName.crash<\/em><\/strong><\/p>\nWhere yyyy_mm_dd<\/em> is date formate .i.e. 2011-05-10<\/em> and hhmmss <\/em>is time formate i.e.\u00a0085655.
\nThis timestamps describes when a particular application crashed at user’s device;
\ndeviceName <\/em>is a name user chose for his\/her device;<\/p>\nSo you will execute this command to symbolicate the crash report;<\/p>\n
.\/symbolicatecrash -A -v myGame_2011-04-26-085655_Ans-iPhone.crash myGame.app.dSYM
\n<\/strong>I’m sure you have now clear idea about different parts of this command;<\/p>\nThe outcome of crash report will replace binary address of your methods and classes names with actual methods and classes names where the application crashed; It will also tell you the exact line number where you got problem;<\/p>\n
