I am facing One problem with APNS. when I made One IPA file with my apple developer account push notification is working properly. But when I am giving that IPA to my client they are again resigning the app with their developer account. In this case push notification is not working. We have changed cert.pem and key.pem also as per their account. If I am making IPA using their credential push notification working properly but not working on resigned IPA. Please someone suggest why this is happening?
Thanks to everyone. I got my solution. Problem was from my server side. In development time while running app from xcode ,notification should be sent from sandbox server so set sandbox as true. After making IPA notification should come from production server so set production to true on server side.
