Question

I have stored 5 images in an mutable array and displayed them randomly on iPhone view by appending them in UIButton . now I want to change the image on a button on which I will click. but in my code only the last image changes not the image on which I called the action.

Answer 1

Here is the code for 3 buttons which highlights the clicked button

-(void) changeButtonImage:(id) sender{
    [button1 setBackgroundImage:[UIImage imageNamed:@"button1Image_off.png"] forState:UIControlStateNormal];
    [button2 setBackgroundImage:[UIImage imageNamed:@"button2Image_off.png"] forState:UIControlStateNormal];
    [button3 setBackgroundImage:[UIImage imageNamed:@"button3Image_off.png"] forState:UIControlStateNormal];

    UIButton *button = sender;

    if (button.tag == 0) {
        [button1 setBackgroundImage:[UIImage imageNamed:@"button1Image_on.png"] forState:UIControlStateNormal];
    }else if (button.tag == 1) {
        [button2 setBackgroundImage:[UIImage imageNamed:@"button2Image_on.png"] forState:UIControlStateNormal];
    }else if (button.tag == 2) {
        [button3 setBackgroundImage:[UIImage imageNamed:@"button3Image_on.png"] forState:UIControlStateNormal];
    }

}

hope this helps…
