+With the new Content Extension feature found in iOS 10, dynamic content can now be displayed as part of a notification without opening an app.
+
+# Map
+Will show a map with a red tipped pin at the coordinates given.
+The map will be centered at the coordinates given.
+
+```yaml
+service: notify.iOSApp
+data:
+  message: Something happened at home!
+  data:
+    push:
+      category: map
+    action_data:
+      latitude: 40.785091
+      longitude: -73.968285
+```
+

+
+# Camera Stream
+
+The notification thumbnail will be a still image from the camera.
+The notification content is a real time MJPEG stream of a camera (assuming the camera supports it).
+
+You can use the attachment parameters `content-type` and `hide-thumbnail` with camera.
+
+You can view an example [here](https://www.youtube.com/watch?v=LmYwpxPKW0g).
+
+```yaml
+service: notify.iOSApp
+data:
+  message: Motion detected in the Living Room
+  data:
+    push:
+      category: camera
+    entity_id: camera.demo_camera
+```

+
+# Combining with actionable notifications
+
+As you can see the `category` key is used to tell the device what kind of content extension to use. You can use the same category identifiers in your own custom [actions](http://localhost:4000/ecosystem/ios/notifications/actions/) to add actions to the content extension.
