触发UITextView中的超链接文本单击和普通文本单击

Question

嗨，我正在尝试为UITextView中的超链接单击和普通文本单击触发单独的单击事件。

如何在UITextView中分隔超链接文本单击和普通文本单击。希望你理解我的问题。

这是我尝试过的。

 override func viewDidLoad() {
    super.viewDidLoad()
    let atributedHtmlText = """
        Hey I dont have hyper link text so trigger func A(). Click <a href="http://www.google.com">I have hyper link so trigger func b here</a> for more information.
        """
    testTV.setAttributedHtmlText(atributedHtmlText)

    let tap = UITapGestureRecognizer(target: self, action: #selector(ViewController.tapFunction))
    testTV.isUserInteractionEnabled = true
    testTV.addGestureRecognizer(tap)
    testTV.delegate = self
 }

 @objc func tapFunction(sender:UITapGestureRecognizer) {
    print("tap working")
 }

 extension ViewController: UITextViewDelegate {
    func textView(_ textView: UITextView, shouldInteractWith URL: URL,
              in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
      print("URL Text Tapped ", URL)
      return false
}

}

定义属性字符串，然后通过定义要点按以打开链接的范围来向其中添加属性。并且不要忘记添加textView的委托方法，并且还要加载YourTextView.delegate =载入中的self。

class ViewController: UIViewController, UITextViewDelegate {
@IBOutlet var textView: UITextView!

override func viewDidLoad() {
    textView.delegate = self.
    let attributedString = NSMutableAttributedString(string: "want to search something on Google! Click Here")
    attributedString.addAttribute(.link, value: "www.google.com", range: NSRange(location: 36, length: 10))

    textView.attributedText = attributedString
}

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    UIApplication.shared.open(URL)
    return false
}

}
