How to get a blinking button?
I want a blinking button. Actually my button look like this:

    [redButton setImage:[UIImage imageNamed:@"Button1.png"] forState: UIControlStateNormal];
    [redButton setImage:[UIImage imageNamed:@"ButtonPressed.png"] forState: UIControlStateHighlighted];

Now I want to change the Buttonpicture in the normal State every second from Button1.png to Button2.png and back to Button1.png and so on... How can I do this?

Thanks for your help and sorry for my bad English.
