map组件在部分机型上无法显示

<map       id="myMap"       style="width: 100%; height: 100%;"       latitude="{{latitude}}"       longitude="{{longitude}}"       markers="{{markers}}"       covers="{{covers}}"       controls="{{controls}}"       show-location     ></map>

Page({   data: {     CustomBar: app.globalData.CustomBar,     StatusBar: app.globalData.StatusBar,     top: app.globalData.CustomBar+40,     isShow: true,     currentTab: 0,     list: [],     latitude: 28.866000,     longitude: 105.401560,     markers: [{       id: 1,       latitude: 28.866000,       longitude: 105.401560,       name: '华阳街道'     }],     covers: [{       latitude: 28.866000,       longitude: 105.401560,       iconPath: '/images/location.png'     }, {       latitude: 28.866000,       longitude: 105.401560,         iconPath: '/images/location.png'     }],     controls: [{       id: 1,       position: {         left: 0,         top: 300 - 50,         width: 50,         height: 50       },       clickable: true     }]   },

测试用小米8，小米9都不能正常显示map组件。小米8有时候又会显示出来一次，关闭之后再点就显示不出来了。iphone7，iphone8和部分安卓手机均显示正常
