+If you need to perform a task between the moment the user taps a button and the moment you'll be able to change the presented item, you can call `displayActivityIndicator()` method on the item manager to hide the current card and display an activity indicator.
+
+This is especially useful if you need to fetch data from a server (in-app purchase price, subscription status, ...) or save data (e.g. Core Data).
+
+Once your task is finished, call one of the methods described in [Changing the Presented Item](#changing-the-presented-item).
+
+**Example**:
+
+~~~swift
+page.actionHandler = { (item: PageBulletinItem) in
+    item.manager?.displayActivityIndicator()
+    // do your task
+    // ...
+    // when your task is finished, transition to the appropriate bulletin item
+    item.displayNextItem()
+}

 ## Automatic Dismissal
 
 If you set the `isDismissable` property to `true`, the user will be able to dismiss the bulletin by tapping outside of the card.
