let textview = uitextview(frame:cgrect(x:10,y:10,width:100,height:100));
        //设置边框粗细
        textview.layer.borderwidth = 1;
        //边框颜色
        textview.layer.bordercolor = uicolor.gray.cgcolor;
        self.view .addsubview(textview);

        //是否可编辑
        textview.iseditable = false;
        //内容是否可选
        textview.isselectable = false;
        //属性font字体,字体颜色,textalignment:对齐方式

        //给文字中电话和网址自动加上链接
        textview.datadetectortypes = []//都不加链接
        textview.datadetectortypes = .phonenumber // 只有电话好吗
        textview.datadetectortypes = .link // 网址
        textview.datadetectortypes = .all //全加上

        let mail = uimenuitem(title:"邮件",action:#selector(viewcontroller.onmail))
