尝试添加在地址上显示标记的地图。因此，我首先使用“定位器”来获取地址的经度和纬度，然后创建地图和以地址坐标为中心的视图。然后，我绘制一个点和一个确定区域的多边形，以检查地址是否在该区域内。它工作正常，但在控制台中显示以下消息：“帧缓冲区不完整！”这是代码：

此消息的来源是什么？我必须使用图层吗？预先感谢。
这是一个webGL错误。 ESRI使用webGL在4.x上进行渲染。我无法重现该错误，因此我猜测它可能与生命周期有关，并且我的客户端执行得更快/更慢。
如果您可以确定webGL在范围内并设置断点，则可以尝试在控制台中执行glGetError（）。
我还将尝试通过从mapView .when回调函数中执行其他代码来确保完全初始化mapView。 webGL可能试图绑定到尚未实例化的内容。
可以调用MapView实例上的.when（）方法来执行仅在加载地图后才能运行的过程。
