Do this way:

Create a new method like this:

- (IBAction)anyBoxButton:(id)sender {
UIButton *anyButton = sender;
if(!checked)
{
[anyButton setImage:[UIImage imageNamed:@"unchecked_checkbox.png"] forState:UIControlStateNormal];
                checked = YES;
            }  else
            if (checked)
            {
            [anyButton setImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateNormal];
             checked = NO;
 }
}

Then in your xib add your action for buttons firstBoxButton and secondBoxButton to above created method. And it should work.
