The concept and sole purpose of IBAction and IBOutlet is to provide Interface Builder with means to connect the xib with your code.

If you don't want to use Interface Builder with your code, you don't need IBAction or IBOutlet, you need them ONLY to use objects (buttons, textfields, etc.) that were instanciated in your xib from your classes.

With that said, mihirpmehta's answer is the correct way to programmatically add UI elements to your view and add actions to them.
