如何在UITextview swift中使用linkTextAttributes

let textView = UITextView()
textView.delegate = self

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    // 处理链接点击事件
    return true
}

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    // 设置链接的样式
    let linkAttributes: [NSAttributedString.Key: Any] = [
        .foregroundColor: UIColor.blue,
        .underlineStyle: NSUnderlineStyle.single.rawValue
    ]
    textView.linkTextAttributes = linkAttributes
    
    // 处理链接点击事件
    return true
}

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    // 设置链接的样式
    let linkAttributes: [NSAttributedString.Key: Any] = [
        .foregroundColor: UIColor.blue,
        .underlineStyle: NSUnderlineStyle.single.rawValue
    ]
    textView.linkTextAttributes = linkAttributes
    
    // 处理链接点击事件
    if URL.scheme == "custom" {
        // 执行自定义操作
        // 例如打开一个新的视图控制器
        let viewController = CustomViewController()
        self.navigationController?.pushViewController(viewController, animated: true)
        return false
    }
    
    return true
}
