Facebook may be integrated into iOS, but it doesn't mean every developer wants to integrate Facebook into their app. In fact, some prefer Google+. For those developers, Google is now hosting a number of tutorials that teach developers how to get the most out of Google+ on iOS.
Last week, Google showed developers how to integrate Google+ Sign-In on iOS. Now the Google+ team is showing developers how to integrate interactive posts in Google+ on iOS.
Check out Google's documentation if you want to learn more about integrating interactive Google+ posts into iOS.
