来自Official Documentation :

When pushing a new interface controller, it is recommended that you pass a context object to the pushControllerWithName:context: method. A context object is your only way to communicate information to the new interface controller about what it should display. A context object can be an existing data object, or it can be a dictionary that you create dynamically and fill with relevant information.

If you prefer to use segues to initiate hierarchical navigation between interface controllers, WatchKit calls the contextForSegueWithIdentifier:inTable:rowIndex: or contextForSegueWithIdentifier: method based on whether the source of the segue was a table row or a button. Use those methods to provide the context object needed to initialize the new interface controller.
