Presenting the Activity View Controller
How you present the controller varies by device. Show it modally on members of the iPhone family and in a popover on tablets. The UIBarButtonSystemItemAction icon provides the perfect way to populate bar buttons linking to this controller.
Best of all, almost no work is required on your end. After users select an activity, the controller handles all further interaction, such as presenting a mail or Twitter composition sheet, adding a picture to the onboard library, or assigning it to a contact.
