iOS support for Google Cloud Messaging

Question

I saw in google\'s developer console that GCM allows to generate a API key for iOS. I searched in the web for any kind of documentation about how to implement Push Notifications

Answer 1

YES

I tried it and it works great. Follow this https://developers.google.com/cloud-messaging/ios/start

This is how it works.

You create app entry at google console. Upload development and production certificated in creation wizard.(You have to upload both) and follow the steps in docs.

Logic works as follows

1. We request device token from apns as usual.
2. Then we send that token to gcm service with provided api.
3. Then gcm sends back a another token.
4. We send that token to app server.
5. App server can send notifications using that token.

Cool Features.

GCM for iOS has some cool features as

• Subscribe to notification based on a particular topic. Ignore others.

• Send Notification to other devices within the app.

If you want to try google sample app. UPDATE: it's Google with a capital G now. Just

pod try Google

There you will get an example in ObjC , swift and even mac app that can send notification.

Update.

Google is moving to Firebase cloud messageing from GCM.
