I am trying to implement push notification in iPhone. I have already done it some months ago. That time, after installing the aps_development.cer certificate, I exported it from keychain as a .p12 file. Then created the .pem certificate with that .p12 file using terminal. This .pem certificate is used in server for push implementation.
But now, when I am checking tutorials for the push implementation, I am seeing that both the .cer and .p12 file have to be converted into .pem. Then both .pem have to be combined using terminal.
Please confirm the steps needed.
