我正在尝试将自定义图像添加到我的mapView，但到目前为止还没有任何运气。加载地图时，我不断收到SIGABRT错误。这是我的代码：
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if annotation.isKindOfClass(NiteOwlAnnotations) {
let reuseId = "test"
var annoView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId)
if annoView == nil {
annoView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
annoView?.image = UIImage(named: "bar-map-icon")
annoView?.canShowCallout = true
} else {
annoView?.annotation = annotation
}
return annoView
/* let annoView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "Default")
// change color of pins.
annoView.pinTintColor = UIColor.blackColor()
annoView.animatesDrop = false
annoView.image = UIImage(named: "bar-map-icon")
annoView.backgroundColor = UIColor.clearColor()
annoView.canShowCallout = true
return annoView
*/
} else if annotation.isKindOfClass(MKUserLocation) {
return nil
}
return nil
}// end func
// --------------------------------------------- -----------------
func createAnnotationForLocation(location: CLLocation) {
let niteOwl = NiteOwlAnnotations(coordinate: location.coordinate)
map.addAnnotation(niteOwl)
}
我已经找到了更多相关信息，但仍然没有运气：
