UIButtons are subclass of UIControl. They use the sendActionsForControlEvents: method to send out events. You can call that method on the button (or control) to have the actions sent.

[theButton  sendActionsForControlEvents: UIControlEventTouchUpInside];

If user dont want to fire action on button,why do you show button,without showing button,u can do action.I think u need dynamic code (without interface builder),the code is

 [button1 addTarget:self action:@selector(action1:) forControlEvents:UIControlEventTouchUpInside];

 -(void) action1:(id)sender;

{ } hope this will help....
