NSString *contentStr = model.content;
contentStr = [contentStr stringByReplacingOccurrencesOfString:@"width" withString:@"wid"];
// 去除样式
NSString *htmlContent =[NSString stringWithFormat:@"<style type=\"text/css\">\n"
                        "table{font-size: 14px !important;color: #666 !important;line-height:20px !important;}"
                        "#div123{font-size:14px !important;line-height:20px !important;color:#666 !important;font-family: \"Microsoft Yahei\", \"微软雅黑\";}\n"
                        "    </style>\n<div id=div123>%@</div> <script type=\"text/javascript\">\n"
                        "\t\tvar ele =document.getElementById('div123').getElementsByTagName('*');\n"
                        "\t\tfor(var i=0;i<ele.length;i++){\n"
                        "\t\t\tif (typeof ele[i].getAttribute('style') == \"string\") {\n"
                        "\t                        var str = ele[i].getAttribute('style');\n"
