Iboutlet output port is an instance variable declared using the keyword Iboutlet. The output declaration in the controller header file should look like this: The Iboutlet statement was added before the instance variable declaration, which indicates that the object was created in Interface Builder. Once you link an object to an exit, you can access it as you would any object you create. As far as the compiler is concerned, Iboutlet does not perform any action. Its only function is to tell interf
