Google has updated its Google+ sharebox with the sole aim of making it easier for users to share.Here are two major updates:
1) Better auto-complete. Now when users start adding recipients, auto-complete will suggest Gmail contacts, device contacts, and people on Google+. And of course: users can also just type in an email address.
2) Suggested recipients. Users often share with certain people more than others (like family, for example), so the new “Suggestions” experience highlights these frequent and/or recent contacts at the top of the sharebox.
While, Auto-complete now suggests Gmail contacts, device contacts, or anyone with a Google+ profile.
Suggested recipients now appear at the top of the Google+ sharebox.
You can either add the Google+ sharebox to your iOS app or you can upgrade to iOS SDK.
