How can I achieve this effect in an iOS App?

I am creating my first ever iOS app, which is based off the Crystal Ball app.How can I make it so that whenever a new random thing is displayed that there is also a different background image and a link to a webpage?

For the random background image part you would need to create an array of UIImages to use as the background and a randomImage method much like the randomPrediction method. You would need to add a UIImage to your storyboard and connect it as an outlet. then whenever the button is pressed/screen is tapped or whatever you would need to call the randomImage method you created that returns a random UIImage from the images array and set that as the background.
