    let attributedString = NSMutableAttributedString(string: kTermsAndPolicy)

    // Set the 'click here' substring to be the link
    attributedString.setAttributes(linkAttributeTermsOfService, range: NSMakeRange(33, 16))

    attributedString.addAttribute(NSFontAttributeName, value: fontOfTerms, range: NSMakeRange(0, attributedString.length-1))

    self.termsTextView.delegate = self
    self.termsTextView.attributedText = attributedString

}

//For iOS 7...9
@available(iOS, deprecated: 10.0)
 func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
    return true
}

@available(iOS 10.0, *)
 func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    return true
 }

}

Answer 1

您必须在故事板中检查Selectable或在代码中进行：

textView.isSelectable = true

Answer 2

try this:

@available(iOS, deprecated: 10.0)
func textView(_ textView: UITextView, shouldInteractWith url: URL, in characterRange: NSRange) -> Bool {
    return true
}

//For iOS 10
@available(iOS 10.0, *)
func textView(_ textView: UITextView, shouldInteractWith url: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    return true
}
