我无法在用户的当前位置放置“常规”引脚。我四处搜寻但找不到多少。现在,在用户的当前位置,我只有位置信标。如何将其更改为常规“引脚”?我尝试了nnotationView?.annotation = annotation但这似乎不起作用。
extension ViewController: MKMapViewDelegate {
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "AnnotationView")
if annotationView == nil {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "AnnotationView")
}
if let title = annotation.title, title == "Park Test" {
annotationView?.image = UIImage(named: "Park icon test")
}
else if annotation === mapView.userLocation {
return nil
}
annotationView?.canShowCallout = true
return annotationView
}
答案 0 :(得分:0)
我的代码使用注释。
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
let identifier = "MyCustomAnnotation"
if annotation is MKUserLocation { return nil }
var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier) as? MKPinAnnotationView
if annotationView == nil {
annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
annotationView?.canShowCallout = true
annotationView?.isEnabled = true
annotationView?.isDraggable = true
let btn = UIButton(type: .detailDisclosure)
annotationView?.rightCalloutAccessoryView = btn
} else {
annotationView?.annotation = annotation
}
return annotationView
}
通过添加此代码来调用委托。
var point = MKPointAnnotation()
self.point.coordinate = location.coordinate
self.point.title = ("Your title")
self.point.subtitle = (" your subs")
self.mapView.addAnnotation(self.point)
//selects the annotation
self.mapView.selectAnnotation(self.point, animated: true)
