title: Is there a way to control which activity types must be shown in activity view controller?
body: <p>I am getting an array of activity types from server side to be shown in my activity view controller. I only see a method to to exclude items. But no way to say I want to show only a specific set of apps on the activity view. It will be great if there is a method that will tell me what apps are populated  on activity view. That way I can compare and exclude the items I dont want.</p>
