【整理】Cocoa中的Segue

scenes are connected by segue objects, which represent a transition between two view controllers.

A Segue Manages the Transition Between Two Scenes

You can set the type of transition (for example, modal or push) on a segue. Additionally, you can subclass a segue object to implement a custom transition.

You can pass data between scenes with the method prepareForSegue:sender:, which is invoked on the view controller when a segue is triggered. This method allows you to customize the setup of the next view controller before it appears on the screen. Transitions usually occur as the result of some event, such as a button being tapped, but you can programmatically force a transition by calling performSegueWithIdentifier:sender: on the view controller.
