arcgis js api4.3添加天地图

4.0以前的版本里面，TileInfo里面有rows、cols属性，但是4.0以后的版本里面没有这两个属性了，添加天地图的时候感觉是缺少属性了，请问一下该怎么处理？或者4.3版本里面怎么添加天地图？
代码：
<script>
var map;
require([
"esri/Map",
"esri/views/MapView",
"esri/layers/WebTileLayer",
"esri/geometry/Point",
"esri/layers/support/TileInfo",
"dojo/domReady!"
], function(
Map,MapView,WebTileLayer,Point, TileInfo
) {
// parser.parse();

var point = new Point({
x: 116.39,
y: 39.91,
spatialReference: {
"wkid": 4326
}
});
//定义地图
var map = new Map({
basemap: "satellite"
// logo:false
});

var view = new MapView({
container: "map",
map: map,

//定位到北京
zoom:14,
center:point
});

//定义瓦片结构
var tileInfo = new TileInfo({
// "rows" : 256,
// "cols" : 256,
// "compressionQuality" : 0,
