A set of methods used by an activity view controller to retrieve the data items to act on.

You can use this protocol in situations where you want to provide the data from one of your app’s existing objects instead of creating a separate
UIActivity object. When implementing this protocol, your object becomes the data provider, providing the view controller with access to the items.
Because the methods of this protocol are executed on your app’s main thread, you should avoid using this protocol in cases where the data objects might take a significant amount of time to create. When creating large data objects, consider using a
UIActivity object instead.
