openlayers包与supermap的iclient-ol包的版本匹配，来自TileLayer的source的state属性的值为true，但网页报错Uncaught (in promise) TypeError: source.getState is not a function

请问是否是因为 SuperMap 自定义的图层源可能未完全实现 OpenLayers 的 Source 标准接口？

若不是，可能是什么原因？

您用的原生OpenLayers加载iServer的服务？试试下面的代码：

var map = new ol.Map({ target: 'map', layers: [ new ol.layer.Tile({ source: new ol.source.XYZ({ url: 'https://iserver.supermap.io/iserver/services/map-world/rest/maps/World/zxyTileImage.png?z={z}&x={x}&y={y}&width=256&height=256', }) }) ], view: new ol.View({ center: [0, 0], zoom: 2 }) });
