1、百度地图集成

<!DOCTYPE html>
<html>
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
	<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
	<style type="text/css">
	body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;font-family:"微软雅黑";}
	</style>
	<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script>
	<title>地图展示</title>
</head>
<body>
	<div id="allmap"></div>  
	
</body>
</html>
<script type="text/javascript">
	// 百度地图API功能
	var map = new BMap.Map("allmap");    // 创建Map实例
	map.centerAndZoom(new BMap.Point(116.404, 39.915), 11);  // 初始化地图,设置中心点坐标和地图级别
	map.addControl(new BMap.MapTypeControl());   //添加地图类型控件
	map.setCurrentCity("北京");          // 设置地图显示的城市 此项是必须设置的
	map.enableScrollWheelZoom(true);     //开启鼠标滚轮缩放
</script>

注意：

<div id="allmap"></div> //外层不可包裹其它元素（如div等），否则地图无法展示

2、android/ios 客户端上为地图覆盖物添加onclick方法

<!DOCTYPE html>
<html>
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
	<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
	<style type="text/css">
		body, html {width: 100%;height: 100%;margin:0;font-family:"微软雅黑";}
		#allmap{width:100%;height:500px;}
		p{margin-left:5px; font-size:14px;}
	</style>
	<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script>
	<title>添加自定义覆盖物</title>
</head>
<body>
	<div id="allmap"></div>
	<p>图示中为房产覆盖物，鼠标移到覆盖物上，自动显示房屋套数</p>
</body>
</html>
<script type="text/javascript">
	// 百度地图API功能
	var mp = new BMap.Map("allmap");
	mp.centerAndZoom(new BMap.Point(116.3964,39.9093), 15);
	mp.enableScrollWheelZoom();
	// 复杂的自定义覆盖物
    function ComplexCustomOverlay(point, text, mouseoverText){
      this._point = point;
      this._text = text;
      this._overText = mouseoverText;
    }
    ComplexCustomOverlay.prototype = new BMap.Overlay();
    ComplexCustomOverlay.prototype.initialize = function(map){
      this._map = map;
      var div = this._div = document.createElement("div");
      div.style.position = "absolute";
      div.style.zIndex = BMap.Overlay.getZIndex(this._point.lat);
      div.style.backgroundColor = "#EE5D5B";
      div.style.border = "1px solid #BC3B3A";
      div.style.color = "white";
      div.style.height = "18px";
      div.style.padding = "2px";
      div.style.lineHeight = "18px";
      div.style.whiteSpace = "nowrap";
      div.style.MozUserSelect = "none";
      div.style.fontSize = "12px"
      var span = this._span = document.createElement("span");
      div.appendChild(span);
      span.appendChild(document.createTextNode(this._text));      
      var that = this;

      var arrow = this._arrow = document.createElement("div");
      arrow.style.background = "url(http://map.baidu.com/fwmap/upload/r/map/fwmap/static/house/images/label.png) no-repeat";
      arrow.style.position = "absolute";
      arrow.style.width = "11px";
      arrow.style.height = "10px";
      arrow.style.top = "22px";
      arrow.style.left = "10px";
      arrow.style.overflow = "hidden";
      div.appendChild(arrow);
     
      div.onmouseover = function(){
        this.style.backgroundColor = "#6BADCA";
        this.style.borderColor = "#0000ff";
        this.getElementsByTagName("span")[0].innerHTML = that._overText;
        arrow.style.backgroundPosition = "0px -20px";
      }

      div.onmouseout = function(){
        this.style.backgroundColor = "#EE5D5B";
        this.style.borderColor = "#BC3B3A";
        this.getElementsByTagName("span")[0].innerHTML = that._text;
        arrow.style.backgroundPosition = "0px 0px";
      }
      
      // 浏览器onclcik方法
      div.onclick = function(){
       	 mp.setZoom(1);
      }
      // 客户端（android/ios）onclcik方法
      div.addEventListener("touchstart", function(){
                         mp.setZoom(1);
                  });
      
      mp.getPanes().labelPane.appendChild(div);
      
      return div;
    }
    ComplexCustomOverlay.prototype.draw = function(){
      var map = this._map;
      var pixel = map.pointToOverlayPixel(this._point);
      this._div.style.left = pixel.x - parseInt(this._arrow.style.left) + "px";
      this._div.style.top  = pixel.y - 30 + "px";
    }
    var txt = "银湖海岸城", mouseoverTxt = txt + " " + parseInt(Math.random() * 1000,10) + "套" ;
        
    var myCompOverlay = new ComplexCustomOverlay(new BMap.Point(116.407845,39.914101), "银湖海岸城",mouseoverTxt);

    mp.addOverlay(myCompOverlay);

</script>

3、ios客户端使用https时自动屏蔽http请求

此时需要引入百度地图api可用 https://api.map.baidu.com/api?v=2.0&ak=您的密钥&=1
