由于 MKPointAnnotation 上无法识别的选择器而导致崩溃
Crash due to unrecognised selector on MKPointAnnotation
我已经为 MKMapView 完成了聚类。
class BaseMKPointAnnotation: MKPointAnnotation {
var index: Int!
}
class ClusteredAnnotationView: MKMarkerAnnotationView {
override init(annotation: MKAnnotation?, reuseIdentifier: String?) {
super.init(annotation: annotation, reuseIdentifier: reuseIdentifier)
// Enable clustering by just setting the clusteringIdentifier
clusteringIdentifier = "AnnotationView"
// clusteringIdentifier = nil
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func prepareForDisplay() {
super.prepareForDisplay()
displayPriority = .defaultHigh
glyphImage = Images.annotationIcon
}
}
extension MKMapView {
func animateToPoint(_ coordinate: CLLocationCoordinate2D, animated: Bool) {
let coordinateRegion = MKCoordinateRegion(center: coordinate, latitudinalMeters: 250.0, longitudinalMeters: 250.0)
self.setRegion(coordinateRegion, animated: animated)
}
}
所以我有我的 ViewController。它在集合视图调用 mapViewAnimateTo 时崩溃。虽然它不经常崩溃，但它确实会崩溃。
class ViewController: UIViewController {
// Method that will add annotations to the mapView.
private func addAnnotation(_ i: Int, _ coordinate: CLLocationCoordinate2D) {
let annotation = BaseMKPointAnnotation()
annotation.index = i // Index to differentiate the annotation.
annotation.coordinate = coordinate
mapView.addAnnotation(annotation)
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if annotation is MKUserLocation {
return nil
}
var annotationView = self.mapView.dequeueReusableAnnotationView(withIdentifier: "Pin")
if annotationView == nil {
annotationView = ClusteredAnnotationView(annotation: annotation, reuseIdentifier: "Pin")
} else {
annotationView?.annotation = annotation
}
return annotationView
}
// This method is called when horizontal collection view stops scrolling.
func mapViewAnimateTo(_ index: Int) {
// Gets the array of points
let point = presenter.getCollectedPoints(index).coordinates
// coordinate to animate.
let coordinate = CLLocationCoordinate2D(latitude: point[0].latitude, longitude: point[0].longitude)
// animates to the coordinate
/*********** Sometimes it crashes here. ***********/
mapView.animateToPoint(coordinate, animated: true)
for annotation in mapView.annotations {
if annotation.coordinate.latitude == coordinate.latitude && annotation.coordinate.longitude == coordinate.longitude {
// mark the annotation as selected.
/*********** Sometimes it crashes here. ***********/
mapView.selectAnnotation(annotation, animated: true)
}
}
}
}
它崩溃并出现以下报告，我该如何解决这个崩溃。在这里，我附上了崩溃的图像
