如何在表情符号中添加NSLinkAttributeName？

// 导入必要的框架
import UIKit

// 创建一个NSMutableAttributedString对象
let attributedString = NSMutableAttributedString()

// 添加表情符号
let emojiAttachment = NSTextAttachment()
emojiAttachment.image = UIImage(named: "smiley") // 表情符号的图片
let emojiString = NSAttributedString(attachment: emojiAttachment)
attributedString.append(emojiString)

// 添加其他文本
let otherText = "这是一段带有表情符号的文本"
let otherAttributedString = NSAttributedString(string: otherText)
attributedString.append(otherAttributedString)

// 添加链接文本
let linkText = "点击这里"
let linkAttributedString = NSAttributedString(string: linkText, attributes: [NSAttributedString.Key.link: URL(string: "https://www.example.com")!])
attributedString.append(linkAttributedString)

// 将NSMutableAttributedString应用于文本视图或标签中
let label = UILabel()
label.attributedText = attributedString
