Experts!
Few days ago i was using previous version of xcode. That time my Distribution certificate worked fine. But now I am using xcode 4.3.2 I got new problem Code Sign error: No unexpired provisioning profiles found that contain any of the keychain's signing certificates.
Also i try all conditions from URL Code Sign error: No unexpired provisioning profiles found that contain any of the keychain's signing certificates
And this certificate is valid.. I it Checked by Key Chain Access. Please anyone send me the correct answer for my problem.
