Objective c 如何在iOS的Mapbox中将属性添加到MGLAnnotation

如何添加自定义属性，如“作业”或“级别”等

---

当前内置的只允许标题、描述和位置。

您必须对

MGLAnnotation

进行子类化，并添加自定义属性，如下所示：

class MyAnnotation: NSObject, MGLAnnotation {

    var coordinate: CLLocationCoordinate2D
    var title: String?
    var subtitle: String?

    // Custom properties
    var job: Job?
    var level: Level?

    init(coordinate: CLLocationCoordinate2D, title: String?, subtitle: String?) {
        self.coordinate = coordinate
        self.title = title
        self.subtitle = subtitle
    }
}
