是否可以强制MapKit在不聚类的情况下显示所有注释? [英] Is it possible to force MapKit to show all annotations without clustering?

问题描述

我有两个都符合MKAnnotation的类，我想知道，有没有一种方法可以强制MapKit在用户缩小并显示所有注释时不将注释聚类?

I have two classes that both conform to MKAnnotation, and I was wondering, is there a way to force MapKit to not cluster the annotation when a user zooms out and display all annotations?

推荐答案

将MKAnnotation的clusteringIdentifier设置为nil.

Set MKAnnotation's clusteringIdentifier to nil.

例如

class BikeView: MKMarkerAnnotationView {

    override init(annotation: MKAnnotation?, reuseIdentifier: String?) {
        super.init(annotation: annotation, reuseIdentifier: reuseIdentifier)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    override var annotation: MKAnnotation? {
        willSet {
            if let bike = newValue as? Bike {
                clusteringIdentifier = nil
            }
        }
    }
}
