How to change button image in swift?

Question

I am working on an app which has a button. The button has no text, image or background.

So what I want to do is to give it an image in the viewDidLoad function.

Answer 1

There's one simple solution:

@IBOutlet var tapButton: UIButton!{
didSet{
let image = UIImage(named: imageColor[randNum])
tapButton.setImage(image, forState: UIControlState.Normal)
}

Besides that, in the Attribute Inspector, Set Button type to 'Custom'

Answer 2

First I would put the image you wanted inside the Assets.xcassets folder. Just drag it in. Then you can call it whatever you want by double-clicking on it. Lets say that it is called "redTap".

For code you would put:

@IBOutlet var tapButton: UIButton!

override func viewDidLoad() {

    super.viewDidLoad()

    let redTapImage = UIImage(named: "redTap")
    tapButton.setImage(redTapImage, forState: UIControlState.Normal)
}
