Answer 1

They are using container views to include child controllers defined somewhere else.

Its actually still a connection between 2 controllers. There is no independent view.

To create a parent-child container relationship at design time, add a container view object to your storyboard scene, as shown in Figure 5-3. A container view object is a placeholder object that represents the contents of a child view controller. Use that view to size and position the child's root view in relation to the other views in the container...

See Implementing a Container View Controller in the Apple docs, chapter Configuring a Container in Interface Builder.

Answer 2

Here container view is using. Container view controllers are a way to combine the content from multiple view controllers into a single user interface. Container view controllers are most often used to facilitate navigation and to create new user interface types based on existing content. please view this link for detail
