    }

}

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;

    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
