# point aggregation

When there are too many markers to be displayed on the map, the markers on the interface may be overlaid, incompletely displayed, and lead to poor overall performance. In response to such problems, the point aggregation capability is introduced.

The usage process is as follows:

MapContext.initMarkerCluster Initialize the configuration of the aggregation point (optional); MapContext.addMarkers specifies the markers involved in aggregation; When MapContext.on('markerClusterCreate', callback) is triggered, update the style of the cluster via MapContext.addMarkers (optional); MapContext.removeMarkers removes the markers participating in the aggregation;

Precautions

-In MiniApp and app-vue, the <map> component is a native component created by the engine. It has the highest level and cannot be controlled by z-index. To draw content on <map>, you can use the marker, controls and other attributes that come with the component, or you can use the <cover-view> component. App side can also use plus.nativeObj.view or subNVue to draw native content, Reference. In addition, there is no hierarchical problem with the nvue file on the App side. Starting from WeChat Basic Library 2.8.3, it supports the same layer rendering of map components, and there is no layer problem anymore.

  • The controls property of the WeChat MiniApp will be deprecated, Details.If the base library used supports same-layer rendering, you can use the <view> component directly, otherwise use the <cover-view> component
  • The map of the nvue file on the App side is more aligned with the MiniApp. The map in vue has the same function as plus.map, and is slightly different from the map of the MiniApp. **It is recommended to use nvue when using map on the App side. **
  • If local images are used on the app side, the resources need to be set to release mode before packaging. Add a new runmode node to app-plus in the manifest file, and set the value to liberate.
  • Do not use <map> components in scroll-view, swiper, picker-view, and movable-view in MiniApp involving hierarchical issues and in app-vue. -In MiniApp and app-vue, css animations are invalid for <map> components.
  • The latitude and longitude used by the map component are the coordinates of the National Bureau of Surveying. To call the uni.getLocation interface, you need to specify the type as gcj02.
  • The underlying engines of <map> components are different on different platforms: WeChat MiniApp are Tencent Maps; H5 is Tencent Maps or Google Maps or Gaode Maps; App, Alipay (Chinese mainland version) MiniApp are Gaode Maps; Baidu MiniApp and QuickApp are Baidu Maps. app-vue can also use Baidu map, configure it in the manifest, and take effect after packaging, but app-nvue only supports Gaode map. In addition, the APIs for selecting maps and viewing map locations only support Amap. If there is no special need on the App side, it is recommended to use Amap.
  • The default api of the map component refers to the WeChat MiniApp. If you need to use plus.map, you can get the native map object through $getAppMap, see details. Note that the map component of nvue is not a plus.map object, and $getAppMap cannot be used
  • The H5 terminal needs to be deployed on the https service to obtain location information, and the local preview (localhost) can still use the http protocol.
  • When using the Chrome browser on a PC device without a GPS module or without a GPS signal, the location information is obtained by connecting to the Google server, and domestic users may fail to obtain the location information.
  • To use the map component on the app side, you need to apply for SDK qualification from a third-party service provider such as AutoNavi or Baidu, and obtain an AppKey. When packaging, you need to check the corresponding module in the manifest file and fill in the Appkey in the SDK configuration. Note that the application package name must match the package name when packaging, and the certificate information must match**. There are detailed application guidelines on the manifest visualization interface.
  • The use of maps on the H5 side is related to positioning. It is necessary to configure the secret key (key) applied by third-party map service providers such as Tencent or Google in manifest.json. Amap requires additional configuration of securityJsCode or serviceHost, for details, refer to Amap Documentation.
  • ios nvue Color does not support ARGB hexadecimal, use rgba(r,g,b,a) instead
  • Pay attention to the conversion of the position coordinate system. There are global GPS standards, national standards, and Baidu private standards. If one standard is used for positioning and the map is another standard, there will be displacement deviations when displayed on the map. It is generally recommended to use the national standard gcj02 uniformly.
# FAQ

Q:应用中使用了 <map> 组件,打包为App时,提示缺少权限模块怎么办?

A:App端原生地图,依赖第三方的 SDK,因此打包移动应用时,需要在manifest中勾选相关的权限并填写 key 信息,详见

Q:国外应用想使用谷歌地图/google地图怎么办?

A: App 3.4+ 已支持 Google 地图, App 3.4 以下版本使用下面的方案

  1. 在web-view下调用谷歌的web地图
  2. 写一个原生插件封装谷歌原生地图,具体参考uni-app插件市场的原生插件开发教程。插件市场已有三方写好的地图插件
