Hi again..
i got this code, and write, but is not working
what iswrong, please help !

BOTON isn't defined in your code. If it's in your .xib file, you'll still need the appropriate IBOutlet in your header file and to make the connection.

In your case, you could probably use [sender setBackgroundImage:AUXIMAGE forState:0] as well.

One other option; you could just set it up in Interfcace Builder - there's options to set the image for the button's various states. Just put the name of the image in the field in the inspector.

thanks... i will try
i will tell you tomorrow !
