Have you already done Project → Clean… and Build again (or most probably you have Build Automatically checked)? Of course you did. So, just look for problems in your res directory. Remove the problem, clean again, and that’s it!
Dear Friends Monitor iOS users, for some devices the app was not working, for others it crashing under certain circumstances. Please wait just 1 day or maybe 2, the time for the App Store process to approve the updated version with all the fixes. Sorry for the problems.
