You might have the IBAction property of a second button, which you can access in your implementation (.m) file with self (e.g. self.secondButtonPropertyName), now you can write the code like below:

-(IBAction)bt1:(id)sender 
{               
   [self.btn2 setBackgroundImage:[UIImage imageNamed:@"vv.png"] forState:UIControlStateNormal];
}

suppose you have two buttons btn1 and btn2

Now after them allocatng memory, you can use below Button selector,

btn1 selector,

-(IBAction)btn1selector:(id)sender
{
[btn2 setbackgroundimage: [uiimage imagenamed:@"your image"]];

}

you can do same for the other button selector.

first you set your both button tag..like btn1 tag =1 and btn2 tag =2

- (IBAction)bt1:(id)sender {
           UIButton *btn = (UIButton*)[self.view viewWithTag:2];
           [btn setBackgroundImage:[UIImage imageNamed:@"vv.png"] forState:UIControlStateNormal];
        }

  - (IBAction)bt2:(id)sender {

       }
