我要顯示圖像MKMapView而不是小別針。有人可以在這里放置一些有用的代碼，或告訴它怎么做嗎？謝謝！編輯-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation {MKPinAnnotationView *pinView = nil; if(annotation != mapView.userLocation) { static NSString *defaultPinID = @"com.invasivecode.pin"; pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID]; if ( pinView == nil ) pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID]; pinView.pinColor = MKPinAnnotationColorGreen; pinView.canShowCallout = YES; pinView.animatesDrop = YES; pinView.image = [UIImage imageNamed:@"pinks.jpg"]; //as suggested by Squatch} else { [mapView.userLocation setTitle:@"I am here"];}return pinView;}我希望我的圖片pinks.jpg會顯示在地圖上，固定位置而不是默認的大頭針視圖（搖滾大頭針形）。但是我仍然得到該引腳的默認圖像。

這是Swift 3的答案。如果可能，它將使注釋視圖出隊，否則將創建新視圖：
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
// Don't want to show a custom image if the annotation is the user's location.
guard !(annotation is MKUserLocation) else {
return nil
}
// Better to make this class property
let annotationIdentifier = "AnnotationIdentifier"
var annotationView: MKAnnotationView?
if let dequeuedAnnotationView = mapView.dequeueReusableAnnotationView(withIdentifier: annotationIdentifier) {
annotationView = dequeuedAnnotationView
annotationView?.annotation = annotation
}
else {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier)
annotationView?.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)
}
if let annotationView = annotationView {
// Configure your annotation view here
annotationView.canShowCallout = true
annotationView.image = UIImage(named: "yourImage")
}
return annotationView
}
Swift 2.2：
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
// Don't want to show a custom image if the annotation is the user's location.
guard !annotation.isKindOfClass(MKUserLocation) else {
return nil
}
// Better to make this class property
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: "yourImage")
}
return annotationView
}

我同意安娜的答案，我想展示一下swift3的外觀。這個答案與其他許多選項一樣，比如調整圖像大小，從array和ect中獲取圖像列表。
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if let annotation = annotation as? PetrolStation {
let identifier = "pinAnnotation"
var view: MKAnnotationView
if let dequeuedView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)
as? MKPinAnnotationView { // 2
dequeuedView.annotation = annotation
view = dequeuedView
} else {
// 3
view = MKAnnotationView(annotation: annotation, reuseIdentifier: identifier)
view.canShowCallout = true
//here We put a coordinates where we like to show bubble with text information up on the pin image
view.calloutOffset = CGPoint(x: -7, y: 7)
//Here this is a array of images
let pinImage = PetrolItem[activePlace].imgPetrol?[activePlace]
//Here we set the resize of the image
let size = CGSize(width: 30, height: 30)
UIGraphicsBeginImageContext(size)
pinImage?.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))
let resizeImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
view.image = resizeImage
//Here we like to put into bubble window a singe for detail Informations
view.rightCalloutAccessoryView = UIButton(type: .detailDisclosure) as UIView
//Here we make change of standard pin image with our image
view.image = resizeImage
}
return view
}
return nil
}
