class DisclamerView: UIView {
     //@objc weak var vc:UIViewController?
     //自定义协议
    @IBInspectable var diy_protocol:String = "diyprotocol"
    //超链接地址
    @IBInspectable var disclamerURLStr:String = " "
    //条款、免责声明描述文字
    @IBInspectable var infoStr = str_disclaimer
    //链接地址描述
    @IBInspectable var linkStr = ""
    //展示文字的大小（用于判断展示区域大小）
    @IBInspectable var font = UIFont.systemFont(ofSize: 13)
    
    lazy var infoTextView:UITextView = {
        let tv = UITextView()
        tv.delegate = self
        tv.isEditable = false
        tv.backgroundColor = UIColor.clear
        tv.isScrollEnabled = false
        //设置页边距上边距10，左右边距各10，底边距0  上，右，下，左
        tv.textContainerInset = UIEdgeInsetsMake(10, 0, 0, -5);
        self.addSubview(tv)
        return tv
    }()
    
    override func awakeFromNib() {
        super.awakeFromNib()
        self.backgroundColor = UIColor.groupTableViewBackground
    }
    
    override func draw(_ rect: CGRect) {
        // Drawing code
        let attri = NSMutableAttributedString(attributedString: NSAttributedString(string: infoStr + linkStr,
                                                                                   attributes:[NSAttributedStringKey.foregroundColor : UIColor.darkGray,
                                                                                               NSAttributedStringKey.font : font]))
        if linkStr != ""{
            attri.addAttributes([NSAttributedStringKey.link:(diy_protocol+"://")],
                                range: ((attri.string) as NSString).range(of: linkStr))
        }
        infoTextView.attributedText = attri
        //左右两天预留5个像素
        infoTextView.frame = CGRect(x: 5, y: 0, width: rect.width - 5*2, height: rect.height)
    }
}

extension DisclamerView:UITextViewDelegate{
    //textView里带有超链接的监听代理
    func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
        //判断超链接协议
        if let sch = URL.scheme,sch == diy_protocol {
            //let ndvc = SFNewsDetailVC(nibName: "SFNewsDetailVC", bundle: nil)
           // ndvc.requstURL = disclamerURLStr;
            //if let vc = vc as? UINavigationController{
            //    vc.pushViewController(ndvc, animated: true)
           // }else{
            //    ndvc.isPresent = true
            //    vc?.present(ndvc, animated: true, completion: nil)
           /// }
            return true
        }
        return false
    }
}

XIB使用：

self.disclamerView.linkStr = @"点击查看详情";
 // CGFloat dh = [STools getDisclaimerStrContentHeightWithDSize:CGSizeMake(SWIDTH - 5*2, 10000) dFont:self.disclamerView.font] + 18;
    self.h_disclamerView.constant = dh;

纯代码使用

    lazy var disclamerView:DisclamerView = {
        let dv = DisclamerView()
        dv.backgroundColor = color_background
        let dh = STools.getDisclaimerStrContentHeight(dFont: dv.font) + 18
        dv.frame = CGRect(x: 0, y: 0,width: swidth, height: dh)
        dv.vc = self
        return dv
    }()

   self.tableView.tableFooterView = disclamerView
