The GPPSignIn class has a trySilentAuthentication method that attempts to automatically sign in the user. This call succeeds if the user has authorized your application in the past, they haven't revoked access to your application, and the app isn't requesting new scopes since they last signed in. If this call succeeds, it calls yourfinishedWithAuth:error: method when sign in is complete.
Add the [signIn trySilentAuthentication] call to the end of your viewDidLoad method.
