How to transmit data via @selector when a user button is clicked?

I am making a button using code. I have the following line of code to run the method when the button is clicked:

[imagesButton addTarget:self action:@selector(photoClicked:) forControlEvents:UIControlEventTouchDown ];

The problem is that I cannot pass data to the method via @selector; If the button had a background image named "background.png", how can I send the name of the background image to the method when the button is clicked? All this should be through code.

Thanks!

Well, if you are trying to change the property of a button by sending a message, your selector should have a sender parameter, which is a pointer to the object it calls, which is your button in this case, For example:

 - (void)photoClicked:(id)sender { UIImage bg = [sender currentBackgroundImage] }

there should be a way to comment on the answer, but I don't know what it is. In any case, the Gobot above me forgot to write (id) before the sender in the method declaration. Otherwise, the Gobot example is fine.
