我正在尝试使 annotation.image 变圆。但我不知道怎么办。我将如何进行 UIImage 轮次。

 //Customize Annotation
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {

    let annotationIdentifier = "Identifier"

    var annotationView: MKAnnotationView! = mapView.dequeueReusableAnnotationView(withIdentifier: annotationIdentifier)

    if annotationView != nil {
        annotationView.annotation = annotation
    } else {
        annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier)


        annotationView.image = profileImage.image

        annotationView.canShowCallout = true
        annotationView.frame = CGRect(x: 0, y: 0, width: 25, height: 25)

        annotationView.autoresizesSubviews = true
        annotationView.rightCalloutAccessoryView = UIButton(type: UIButtonType.detailDisclosure) as UIView
    }


      return annotationView
}
