GCM registration is not ready with auth credentials in ios9

Question

Hi i am using GCM for push notification, it is working fine in iOS8 but in iOS9 it is giving error \"GCM registration is not ready with auth creden

Answer 1

I had the same issue, after signing the app using a production certificate.

And the steps to make it work again are (this worked on 9.2 and 9.3 devices):

1. Put back kGGLInstanceIDAPNSServerTypeSandboxOption:@YES (production needs this to be NO)
2. Under "build settings/Code Signing/Code signing identity" use the iPhone Distribution linked the GCM project (com.xxxx.yyy) and for Provisioning Profile, change back from Automatic to iOS Team Provisioning Profile:com.xxxx.yyy

Build, run, and wait a few minutes. For one of the tests, it took 15 minutes to register.
