要想使用自定义的链接颜色，需要在设置attributedText属性之前，把linkTextAttributes置为空。

showTextView.linkTextAttributes = [:]
showTextView.attributedText = show

实现协议：

extension PrivacyViewController: UITextViewDelegate {func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {// 跳到隐私协议if URL.scheme == "protocol" {guardlet host = AppConfig.config?.htmlHosts?.randomElement(),let url = NSURL(string: host + "/mobile/agreement.html") as URL? else {return false}dismiss(animated: true){}let vc = AppWebViewController()vc.url = urlAppDelegate.shared.navigation.push(vc)}return false}
}
