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'
