XIB使用：

self.disclamerView.linkStr = @"點擊查看詳情"; // 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
