UITextField, becomeFirstResponder, resignFirstResponder

When a UITextField object becomes first responder the keyboard magically appears. When it resigns first responder the keyboard magically slides away. What is causing this to happen? Is there something constantly watching in the background and makes the keyboard appear/disappear when it notices a text field becoming/losing first responder?

You should have a look at the Notifications section in the Cocoa Fundamentals Guide. There's anything you need to know about notifications there : from definition to use cases.
