Swift MKPointAnnotation自定义图像 [英] Swift MKPointAnnotation custom Image

问题描述

我尝试快速为我的MKPointAnnotation创建一个自定义的徽章"，但是由于MKPointAnnotation没有像image这样的任何属性，它失败了

I try to create a custom "badget" for my MKPointAnnotation in swift, but it fails as MKPointAnnotation does not have any property like image

 var information = MKPointAnnotation()
    information.coordinate = location 
    information.title = "Test Title!"
    information.subtitle = "Subtitle"
    information.image = UIImage(named: "dot.png") //this is the line whats wrong
    Map.addAnnotation(information)

有人找到了这样的快速解决方案吗?

Anyone figured out a swift like solution for that?

推荐答案

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {

    if !(annotation is MKPointAnnotation) {
        return nil
    }

    var annotationView = mapView.dequeueReusableAnnotationViewWithIdentifier("demo")
    if annotationView == nil {
        annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "demo")
        annotationView!.canShowCallout = true
    }
    else {
        annotationView!.annotation = annotation
    }

    annotationView!.image = UIImage(named: "image")

    return annotationView

}
