如何在点击时运行自定义功能的UITextView中添加超链接文本

import UIKit

class ViewController: UIViewController, UITextViewDelegate {
    @IBOutlet weak var textView: UITextView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        textView.delegate = self
        
        // 创建一个NSMutableAttributedString对象
        let attributedString = NSMutableAttributedString(string: "点击这里打开百度")
        
        // 设置超链接属性
        let linkAttributes: [NSAttributedString.Key: Any] = [
            .link: URL(string: "https://www.baidu.com")!,
            .foregroundColor: UIColor.blue,
            .underlineStyle: NSUnderlineStyle.single.rawValue
        ]
        
        // 将超链接属性应用到文本中的指定范围
        attributedString.setAttributes(linkAttributes, range: NSRange(location: 2, length: 4))
        
        // 将NSMutableAttributedString对象设置为UITextView的attributedText属性
        textView.attributedText = attributedString
        
        // 设置UITextView可交互，以便响应链接点击事件
        textView.isSelectable = true
        textView.isEditable = false
    }
    
    func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
        // 判断点击的文本是否为超链接文本
        if let link = textView.attributedText.attribute(.link, at: characterRange.location, effectiveRange: nil) as? URL {
            // 执行自定义功能的代码逻辑，例如打开一个网页
            UIApplication.shared.open(link)
            return false
        }
        
        return true
    }
}
