Answer 1

Not really sure what you need, but if the button was created in code using the images from the array, you can use a simple pointer equality check:

for (UIImage *img in array)
    if (button.imageView.image == img)
        // whatever

Answer 2

set the button.tag to match the index in the array of images

[images objectAtIndex: button.tag]

will give you the image associated with the button
