我的需求是
1、显示地图
2、在地图上增加覆盖物
3、地图距离底部边距有90rpx
主要使用到原生组件map和cover-view

实现效果：

代码我是使用的mpvue开发。源码如下：

<template><div class="map-clock"><map id="map" longitude="113.324520" latitude="23.099994" scale="14" :markers="markers" :polyline="polyline" show-location></map><cover-view class="controls"><cover-view>地图控件</cover-view></cover-view><footer class="ac-footer"><div class="aui-footer-btn aui-order-price"><span class="aui-order-price-text"><span>打卡次数 </span><span class="de-price">500</span></span></div><a href="javascript:;" class="aui-footer-btn">坐标打卡</a></footer></div>
</template>

<script>
export default {data() {return {markers: [{iconPath: "../../static/images/map/marker.png",id: 0,latitude: 23.099994,longitude: 113.324520,width: 50,height: 50}],polyline: [{points: [{longitude: 113.3245211,latitude: 23.10229}, {longitude: 113.324520,latitude: 23.21229}],color: "#FF0000DD",width: 2,dottedLine: true}]}},
}
</script>

<style lang="less" scoped>
.map-clock {width: 100%;height: calc(100vh - 90rpx);position: relative;#map {width: 100%;height: 100%;}// 底部按钮.ac-footer {width: 100%;position: relative;z-index: 102;display: flex;align-items: center;padding: 0;background-color: rgba(255, 255, 255, 0.96);box-shadow: 0 -2px 15px #dedede;height: 90rpx;.aui-footer-btn {flex: 1;display: flex;flex-direction: column;justify-content: center;align-items: center;color: #fff;background: #4499ff;height: 100%;font-size: 14px;font-weight: bold;.de-price {font-size: 18px;font-weight: bold;}}.aui-order-price {background: #fff;color: #4499ff;position: relative;}}
}
.controls {position: absolute;top: 30rpx;left: 30rpx;height: 50px;background: #4499ff;width: 100rpx;height: 100rpx;border-radius: 10rpx;box-shadow: 0 -2px 15px #dedede;font-size: 12px;
}
</style>
