How change the current image's button on Click?

In my file .h :

-(IBAction)Boutton:(id)sender;

In my file .m :

-(IBAction)Boutton:(id)sender
{ 

    UIImage *btnImage1 = [UIImage imageNamed:@"x.png"];
    [sender setImage:btnImage1 forState:UIControlStateNormal];

}

With this code i can change the image of my clicked button (sender).

The question is, how can I change the images of开发者_开发百科 the others buttons (not the sender one) ?

For example if (sender.tag == 4) i would like To have something like :

-(IBAction)Boutton:(id)sender
{ 

    UIImage *btnImage1 = [UIImage imageNamed:@"x.png"];
    [sender setImage:btnImage1 forState:UIControlStateNormal];

    UIImage *btnImage2 = [UIImage imageNamed:@"Y.png"];

    [Boutton:(1) setImage:btnImage2 forState:UIControlStateNormal];
    [Boutton:(2) setImage:btnImage2 forState:UIControlStateNormal];
    [Boutton:(3) setImage:btnImage2 forState:UIControlStateNormal];

}

Simply link the other buttons to outlets of your UIViewController subclass. So that from -(IBAction)Boutton:(id)sender you can change their image by accessing them through their properties.

Use tag parameters of UIButton.

UIButton *btn = (UIButton *)sender;

if(btn.tag == 1)
{
...
}

choose the button and assign the image you want then from the utilities bar change the state config to Highlighted then assign the on click image
