Tint color of button does not change to match background color.

Thanks for the answer! (funFactButton tintColor = randomColor did not work.)

import UIKit

class ViewController: UIViewController { @IBOutlet weak var funFactLabel: UILabel! @IBOutlet weak var funFactButton: UIView!

let factBook = FactBook()
let colorWheel = ColorWheel()

override func viewDidLoad() {
    super.viewDidLoad()
    funFactLabel.text = factBook.randomFact()

    // Do any additional setup after loading the view, typically from a nib
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

    // Dispose of any resources that can be recreated.
}

@IBAction func showFunFact() {
    var randomColor = colorWheel.randomColor()
    view.backgroundColor = randomColor
    funFactButton.tintColor = randomColor
    funFactLabel.text = factBook.randomFact()

}

}

Hi Max

Thanks for posting your code for me. The problem looks to be that you have:

UIViewController { 
    @IBOutlet weak var funFactLabel: UILabel! 
    @IBOutlet weak var funFactButton: UIView!

Instead of

class ViewController: UIViewController {
    @IBOutlet weak var funFactLabel: UILabel!
    @IBOutlet weak var funFactButton: UIButton!

The only difference between the two is, if you noticed, that funFactButton should be of type UIButton as opposed to UIView.

Interface Builder is a little fiddly so what I think might have happened is when you have correctly Option-Clicked on the button and then dragged it in to your code I believe it has actually pulled across your view instead.

Would you be able to try deleting:

    @IBOutlet weak var funFactButton: UIView!

From your code and then going back in to interface builder. Once there double click on the edge of the button so that the rest of the view fades out slightly, this way you'll know that any actions you do will be related to the button rather than the view itself. Once you have the button selected simply do as you did before and Option-Click and drag in to your code in the same place as before. So long as you name the new IBOutlet the same as before and as long as it then shows up as UIButton such as:

    @IBOutlet weak var funFactButton: UIView!

Then you should be good to go.

Any problems just let me know.

Thanks Nick Yup I had the same issue! I wonder how that happened? Anyway I just reconnected it and bingo.

I guess it would not have worked if we just changed the name manually to UIButton!? It's code so why wouldn't it work?

I've got the same problem here.
