配置标记的海拔高度
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
您可以自定义添加到 3D 地图中的标记的海拔高度。
以下代码示例演示了如何使用 Marker 结构体配置标记的高度和高度模式，以拉伸标记并设置其高度。
Swift
@State var extrudedMarker: Marker = .init(
position: .init(
latitude: 37.78980534,
longitude: -122.3969349,
altitude: 50.0),
altitudeMode: .relativeToGround,
collisionBehavior: .required,
extruded: true,
drawsWhenOccluded: true,
sizePreserved: true,
zIndex: 0,
label: "Extruded marker"
)
