更改MKMapView用户位置注释
更改MKMapView用户位置注释
提问于 2016-04-28 06:55:35
我正在尝试将MKMapView上的用户默认位置注释从蓝色更改为名为geo的自定义图像。当我设置断点时，将其设置为geo就是命中线，但是这两个点(用户默认和乘客点都是默认的红色针点注释)是我设置错了吗，还是有特定的图像规定？
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if annotation.isKindOfClass(PassengerLocation) == false {
//User location
let userIdentifier = "UserLocation"
var annotationView = mapView.dequeueReusableAnnotationViewWithIdentifier(userIdentifier)
if annotationView == nil {
annotationView = MKPinAnnotationView(annotation:annotation, reuseIdentifier:userIdentifier)
}
annotationView!.annotation = annotation
annotationView!.canShowCallout = true
// THIS IS NOT WORKING, DEFAULT RED PIN POINT STILL SHOWING
annotationView!.image = UIImage(named: "geo")
return annotationView
}
let identifier = "PassengerLocation"
if let annotationView = mapView.dequeueReusableAnnotationViewWithIdentifier(identifier) {
annotationView.annotation = annotation
return annotationView
} else {
let annotationView = MKPinAnnotationView(annotation:annotation, reuseIdentifier:identifier)
annotationView.enabled = true
annotationView.canShowCallout = true
let btn = UIButton(type: .DetailDisclosure)
annotationView.rightCalloutAccessoryView = btn
return annotationView
}

这是可行的：
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if annotation.isEqual(mapView.userLocation) {
let annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "userLocation")
annotationView.image = UIImage(named: "geo")
return annotationView
}

这对我很有效
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
// want to show a custom image if the annotation is the user's location.
guard !annotation.isKindOfClass(MKUserLocation) else {
let annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "userLocation")
annotationView.image = UIImage(named: "icon_coordinates_self")
return annotationView
//return nil
}
let annotationIdentifier = "AnnotationIdentifier"
var annotationView: MKAnnotationView?
if let dequeuedAnnotationView = mapView.dequeueReusableAnnotationViewWithIdentifier(annotationIdentifier) {
annotationView = dequeuedAnnotationView
annotationView?.annotation = annotation
}
else {
let av = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier)
av.rightCalloutAccessoryView = UIButton(type: .DetailDisclosure)
annotationView = av
}
if let annotationView = annotationView {
// Configure your annotation view here
annotationView.canShowCallout = true
annotationView.image = UIImage(named: "Annotation_map")
}
return annotationView

如果要自定义镜像，请使用常规MKAnnotationView。用大头针，你所能做的就是改变颜色。
