在swift中使URL链接具有属性并可单击，以及可编辑的文本视图

let textView = UITextView(frame: CGRect(x: 0, y: 0, width: 300, height: 200))
textView.isEditable = true

let text = "点击这里访问我们的网站: https://www.example.com"
let attributedText = NSMutableAttributedString(string: text)

// 找到URL的范围
if let urlRange = text.range(of: "https://www.example.com") {
    let nsURLRange = NSRange(urlRange, in: text)
    
    // 设置URL的属性
    attributedText.addAttribute(.link, value: "https://www.example.com", range: nsURLRange)
    attributedText.addAttribute(.foregroundColor, value: UIColor.blue, range: nsURLRange)
    attributedText.addAttribute(.underlineStyle, value: NSUnderlineStyle.single.rawValue, range: nsURLRange)
}

// 将富文本字符串设置给textView
textView.attributedText = attributedText

textView.dataDetectorTypes = .link

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    // 在这里处理链接点击事件
    UIApplication.shared.open(URL, options: [:], completionHandler: nil)
    return false // 返回false表示不使用默认行为
}

textView.delegate = self
