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

While some Google APIs work with iOS GCM is for Android only. The only way to send push notifications to iOS devices is through the Apple push notification system. Google would have to support this.

You can always us something like Urban Airship if you want to push to multiple platforms.
