Rotate MKAnnotation image not title - ios

Question

I am trying to rotate an image for a MKAnnotation and while I succeed to do so, the title of it is also rotating. Is there a way to keep the title straight? Any help would be really appreciated!
Here is my code:
In viewDidLoad():
let middlePoint = CustomPointAnnotation()
middlePoint.coordinate = self.coordinates
middlePoint.imageName = "routemiddle"
middlePoint.title = "\(hourDetailedRoute):\(minuteDetailedRoute)"
middlePoint.courseDegrees = self.vehicleChangeCourse
self.mapa.addAnnotation(middlePoint)
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if !(annotation is CustomPointAnnotation) {
return nil
}
let reuseId = "annotation"
var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId)
if anView == nil {
anView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
anView!.canShowCallout = true
}
else {
anView!.annotation = annotation
}
let cpa = annotation as! CustomPointAnnotation
anView!.image = UIImage(named:cpa.imageName)
anView!.transform = CGAffineTransformRotate(self.mapa.transform, CGFloat(degreesToRadians(cpa.courseDegrees)))
return anView
}
class CustomPointAnnotation: MKPointAnnotation {
var imageName: String!
var courseDegrees = 0.0
}

I have figured it out! I just needed to rotate only the image instead of rotating the whole view.
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if !(annotation is CustomPointAnnotation) {
return nil
}
let reuseId = "annotation"
var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId)
if anView == nil {
anView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
anView!.canShowCallout = true
}
else {
anView!.annotation = annotation
}
let cpa = annotation as! CustomPointAnnotation
var imagePin = UIImage(named:cpa.imageName)
imagePin = imagePin?.rotateImage(cpa.courseDegrees)
anView!.image = imagePin
return anView
}
