How do I get the Pin to change it's image? - swift

Question

I have the problem, that my Annotation is still a pin! I want the Button and the picture, for the information displayed about the User and it works. But it doesn't change the look of the pin on the Map!
This is my annotationView:
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
// 1
let identifier = "pinAnnotation"
// 2
if annotation.isKindOfClass(pinAnnotation.self) {
// 3
var annotationView = mapView.dequeueReusableAnnotationViewWithIdentifier(identifier)
if annotationView == nil {
//4
annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
annotationView!.canShowCallout = true
// 5
let btn = UIButton(type: .InfoDark)
annotationView!.rightCalloutAccessoryView = btn
resultImgArray[0].getDataInBackgroundWithBlock {
(imageData: NSData?, error: NSError?) -> Void in
if error == nil {
let imageView = UIImageView(frame:CGRectMake(0,0,45,45))
imageView.image = UIImage(data: imageData!)
annotationView!.leftCalloutAccessoryView = imageView
}
}
} else {
// 6
annotationView!.annotation = annotation
}
return annotationView
}
return nil
}
This is my pinAnnotationView.swift as MKAnnotationView:
import UIKit
import MapKit
import CoreLocation
class pinAnnotationView: MKAnnotationView {
override init(frame :CGRect) {
super.init(frame: frame)
}
override init(annotation: MKAnnotation?, reuseIdentifier: String?) {
super.init(annotation: annotation, reuseIdentifier: reuseIdentifier)
var frame = self.frame
frame.size = CGSizeMake(80, 80)
self.frame = frame
self.backgroundColor = UIColor.clearColor()
self.centerOffset = CGPointMake(-5, -5)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func drawRect(rect: CGRect) {
// Drawing code
UIImage(named: "carlogo.png")?.drawInRect(CGRectMake(30, 30, 30, 30))
}
}
Here is the image

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if annotation.isMember(of: MKUserLocation.self) {
return nil
}
let identifier = "someID"
var dequeuedAnnotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)
if dequeuedAnnotationView == nil{
dequeuedAnnotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: identifier)
configureDetailView(annotationView: dequeuedAnnotationView!)
}
return dequeuedAnnotationView
}
func configureDetailView(annotationView: MKAnnotationView) {
var frame = self.frame
frame.size = CGSizeMake(80, 80)
self.frame = frame
self.backgroundColor = UIColor.clearColor()
self.centerOffset = CGPointMake(-5, -5)
annotationView.image = UIImage(named:"yourImage")
}
And use annotationView.detailCalloutAccessoryView = "yourView" in this case will be frame.
I hope works for you
