How to add a hyperlink button on iOS Swift?

Question

I'm trying to make a clickable link over a button. I made this using some Internet help but it didn't work :

    @IBAction func linkClicked(sender: AnyObject) {
    openUrl("http://fr.envisite.net/t5exce")
}
func openUrl(url:String!) {

    let targetURL=NSURL(fileURLWithPath: url)

    let application=UIApplication.sharedApplication()

    application.openURL(targetURL);

}

It doesn't do anything, no error, just the button doesn't get me on Safari (I use the iOS simulator)

You're creating a file URL with a web url string. Use the NSURL String constructor instead.

@IBAction func linkClicked(sender: AnyObject) {
    openUrl("http://fr.envisite.net/t5exce")
}

func openUrl(urlStr:String!) {

     if let url = NSURL(string:urlStr) {
UIApplication.sharedApplication().openURL(url)
}

   }

Swift3

@IBAction func linkClicked(sender: Any) {
    openUrl(urlStr: "http://fr.envisite.net/t5exce")
}

func openUrl(urlStr: String!) {
    if let url = URL(string:urlStr), !url.absoluteString.isEmpty {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    }
}

Thank you, I don't see what's different but it works ^^ – Orionss Sep 08 '16 at 14:04
@Orionss - fileURLWithPath - we are using for local path , NSURL(string: - we are using server path or web url Path, – Anbu.Karthik Sep 08 '16 at 14:05
@Orionss - happy to hear, – Anbu.Karthik Sep 08 '16 at 14:05

In Swift 3 you should use `URL` instead of `NSURL` - that way, no need for `url as URL`. – Eric Aya Apr 10 '17 at 09:00
I am using a textview for my link, but unable to connect to this function: func linkClicked or make an action. What am I doing wrong? – LizG May 10 '17 at 22:47
@LizG - are you created the function in your current class – Anbu.Karthik May 11 '17 at 04:45
Yes. After viewDidLoad – LizG May 11 '17 at 04:58
@LizG - can you attach the project I will check – Anbu.Karthik May 11 '17 at 04:59
I am not near my mac atm but will as soon as i am. Thank you – LizG May 11 '17 at 05:00
