This method involves syncing your device with iTunes. After syncing, crash reports will be copied to a specific location on your hard drive. This method is also documented at https://developer.apple.com/library/ios/#qa/qa1747/_index.html.
- Sync your device with iTunes on your desktop.
- After syncing, look for crash logs in the correct directory. See below for a list of directories for each operating system.
Mac OS X:
C:\Documents and Settings\<USERNAME>\Application Data\Apple Computer\Logs\CrashReporter\MobileDevice\<DEVICE_NAME>
Windows Vista or later
(NOTE FOR MAC USERS: ~/Library is hidden by default on Mac OS X. To easily get this folder, open the Finder application, then hold the "option" key while clicking on the "Go" menu. You should see a menu item for "Library." Click on that, then continue navigating to Logs, CrashReporter, etc.)
- In this directory, look for files starting with "ITmanager.net".
