Answer 1

The same solution for Swift 3 using extensions :

A. Add extension -

extension UITextView {
    func hyperLink(originalText: String, hyperLink: String, urlString: String) {
        let style = NSMutableParagraphStyle()
        style.alignment = .center
        let attributedOriginalText = NSMutableAttributedString(string: originalText)
        let linkRange = attributedOriginalText.mutableString.range(of: hyperLink)
        let fullRange = NSMakeRange(0, attributedOriginalText.length)
        attributedOriginalText.addAttribute(NSLinkAttributeName, value: urlString, range: linkRange)
        attributedOriginalText.addAttribute(NSParagraphStyleAttributeName, value: style, range: fullRange)
        attributedOriginalText.addAttribute(NSFontAttributeName, value: UIFont.systemFont(ofSize: 10), range: fullRange)
        self.linkTextAttributes = [
            NSForegroundColorAttributeName: UIConfig.primaryColour,
            NSUnderlineStyleAttributeName: NSUnderlineStyle.styleSingle.rawValue,
        ]
        self.attributedText = attributedOriginalText
    }
}

B. Add link url - let linkUrl = "https://www.my_website.com"

C. Implement UITextViewDelegate in your ViewController like this -

 class MyViewController: UIViewController, UITextViewDelegate { 
 }

D. Add delegate method to handle tap events -

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
    if (URL.absoluteString == linkUrl) {
        UIApplication.shared.openURL(URL)
    }
    return false
    }
}

E. And finally, things to make sure for your UITextView under attribute inspector -

1. Behaviour - Editable is turned OFF & Selectable is turned ON.
2. Data Detectors - Link is turned ON.

Usage -

textView.hyperLink(originalText: "To find out more please visit our website", hyperLink: "website", urlString: linkUrl)

Cheers & happy coding!
