Answer 1

You can use the button tag property; so inside your IBAction method

 - (IBAction)buttonClicked:(UIButton *)sender { if (sender.tag == 1) { // perform your 1st functionality button.tag = 2; //To perform 2nd functionality } else if (sender.tag == 2) { // perform your Second functionality button.tag = 3; //To perform 3rd functionality } else if (sender.tag == 3) { // perform your 3rd functionality button.tag = 1; // To perform 1st functionality } } 

EDIT:

Answer 2

Just do it by tags. You will save a lot of memory and will work fine.

Answer 3

Or you can use these methods.

 - (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents; 

& use later

 - (void)removeTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents; 

This will solve your problem. I hope so.
