我试图将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,它会将它设置为地理位置,但这两个点(用户默认和Passenger点都是默认的红色精确定位注释)我是否设置了错误,或者是否存在某些图像规定?更改MKMapView用户位置注释
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
}
}
