Application crash logs are transfered to your computer each time you do a sync with the device, in the iTunes. Thus, first step is to sync with iTunes:
AppData folder is hidden by default, , so you need to reveal it by typing the address in My Computer’s address bar.
Windows XP –
Location is here:
C:/Documents and Settings/<USERNAME>/Application Data/Apple computer/LogsCrashReporter/<DEVICE_NAME>
is your login username. Application Data folder is usually hidden by default, so you need to reveal it in the same way as in Vista — by typing in and pressing Enter.
When an application crashes on the
iPhone or iPod touch, a "crash report"
is stored on the device. Crash reports
describe the conditions under which
the application terminated, in most
cases including a complete stack trace
for each executing thread, and are
typically very useful for debugging
issues in the application.
When the user synchronizes their
device using iTunes, crash reports are
copied to a directory on the user's
computer. If the application was
distributed via the App Store and the
user has chosen to submit crash logs
to Apple, the crash log will be
uploaded and the developer can
download it via iTunes Connect. For
applications that have been
distributed using Ad Hoc or Enterprise
methods, getting crash reports
requires user cooperation.
Specifically, the user will need to
retrieve the crash report from the
directory where it was copied by
iTunes. Depending on the platform, the
directory is:
Mac OS X:
~/Library/Logs/CrashReporter/MobileDevice/
Windows XP: C:\Documents and
Settings\\Application
Data\Apple
Computer\Logs\CrashReporter\MobileDevice\
Windows Vista or 7:
C:\Users\\AppData\Roaming\Apple
Computer\Logs\CrashReporter\MobileDevice\
is the user's login name
for the computer. is the
name of the iPod touch or iPhone, for
example, "John's iPhone".
You are only interested in .crash
files. The crash report's file name
begins with the application name and
contains date/time information. In
addition, will appear at
the end of the file name, before the
extension.
You can use Test Flight sdk to get to know the crash report , and also other info related to crash like how did get crashed. Here is the link where you will know how to use::
Open Xcode. Go to the organizer window. Select one of your attached devices. Look for a tab named 'Device logs' on the right.
Once you have released your app to the public, you will get crash logs from users through iTunes Connect.
