How can I create a “hyperlink” with Swift?

Question

I\'m trying to make separate pieces of text UILabels clickable. What I\'m looking for is commonly known as a hyperlink in web development.

Answer 1

The One approach would be something like the following.
The assumptions are:

• self.urls is a string array containing the urls associated with each UILabel.
• Each UILabel tag has been set to the corresponding index in the array
• labelTapped: is set as the touchUpInside handler for the labels.

import Foundation
import UIKit

class urltest {

    var urls:[String]

    init() {
        self.urls=[String]()  // Load URLs into here
    }

    @IBAction func labelTapped(sender:UILabel!) {

        let urlIndex=sender.tag;
        if (urlIndex >= 0 && urlIndex < self.urls.count) {
           self.openUrl(self.urls[urlIndex]);
        }

    }

    func openUrl(url:String!) {

        let targetURL=NSURL.URLWithString(url)

        let application=UIApplication.sharedApplication()

        application.openURL(targetURL);

    }
}

Swift 3 I created a LinkUILabel class in github: https://github.com/jorgecsan/LinkUILabel With this you only need add the url inspectable as the shows the image: or assign the url variable programmatically:

linkUILabel.url = "www.example.com"

If you want to implement by your self also I found that solution!:)

using:

// This is the label
@IBOutlet weak var label: UILabel!

override func loadView() {
    super.loadView()

    // This is the key
    let tap = UITapGestureRecognizer(target: self, action: #selector(self.onClicLabel(sender:)))
    label.isUserInteractionEnabled = true
    label.addGestureRecognizer(tap)
}

// And that's the function :)
func onClicLabel(sender:UITapGestureRecognizer) {
    openUrl("http://www.google.com")
}


func openUrl(urlString:String!) {
    let url = URL(string: urlString)!
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    } else {
        UIApplication.shared.openURL(url)
    }
}

Hope it helps!:)

Hyperlink via UITextView

var termsConditionsTextView: UITextView = {
let view = UITextView()
 view.backgroundColor = .clear
 view.textAlignment = .left
 
 let firstTitleString = "By registering for THIS_APP I agree with the "
 let secondTitleString = "Terms & Conditions"
 let finishTitleString = firstTitleString + secondTitleString
 let attributedString = NSMutableAttributedString(string: finishTitleString)
 attributedString.addAttribute(.link, value: "https://stackoverflow.com", range: NSRange(location: firstTitleString.count, length: secondTitleString.count))
 
 view.attributedText = attributedString
 view.textContainerInset = .zero
 view.linkTextAttributes = [
     .foregroundColor: UIColor.blue,
     .underlineStyle: NSUnderlineStyle.single.isEmpty
 ]
 
 view.font = view.font = UIFont(name: "YOUR_FONT_NAME", size: 16)
 view.textColor = UIColor.black
 
 return view }()
