UIButton label not showing

Question

I have the following code

let width = UIScreen.mainScreen().bounds.width    
let linkLabel = UILabel(frame: CGRect(x: 8, y: contentHeight, width: 100, height: labelHeight))
    let linkButton = UIButton(frame: CGRect(x: 108, y: contentHeight, width: width - 108, height: labelHeight))
    mainScrollView.addSubview(linkLabel)
    mainScrollView.addSubview(linkButton)
    linkLabel.text = "Link:"
    linkButton.addTarget(self, action: #selector(linkButtonPressed), forControlEvents: .TouchUpInside)
    linkButton.setTitle("http://example.com", forState: .Normal)
    linkButton.layer.borderWidth = 1.0

    mainScrollView.contentSize = CGSize(width: view.frame.width, height: contentHeight)

And when view loads i see the following picture (Note that button is black rectangle):

So title is not visible but when i click on the button i can fetch its title property

func linkButtonPressed(sender: UIButton) {
    print("button title = \(sender.titleLabel?.text)")
}

And i get the button title = Optional("http://example.com") but anyway button title is not visible. Any suggestions?

Try making it bigger (taller) first - it might be too small to display the text. — sschale, May 30 '16 at 08:46
How much is the "width" variable? Seems thats only a few pixels. — derdida, May 30 '16 at 08:47
check your button width is perfectly fit with scrollview width — Anbu.Karthik, May 30 '16 at 08:55
@Anbu.Karthik mainScrollView width is equal to main view width — Andrey M., May 30 '16 at 09:06
Have you tried `linkButton.setTitleColor(color: UIColor.blackColor(), forState: .Normal)` ? — orxelm, May 30 '16 at 09:07

Your button title is display but in white color.Give any color to button title it is there.There is no problem in your code.

linkButton.setTitle("http://example.com", forState: .Normal)
linkButton.setTitleColor(UIColor.redColor(), forState: UIControlState.Normal)

You skipped one step. You should add title color :-

linkButton.setTitleColor(UIColor.blackColor(), forState: .Normal)
