不能选择MKViewAnnotation两次?

尝试使用此方法 deselectAnnotation

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
     //do what you need here
     mapView.deselectAnnotation(view.annotation, animated: true)
}

希望这有帮助

这将允许显示 callout

internal func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {

    view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(mapPinTapGestureRecognizer)))
}

@objc private func mapPinTapGestureRecognizer(gestureRecognizer: UITapGestureRecognizer) {

    // Will get called on the second time the pin is selected.
    // And then, after that, it will be called every time.
}

当注释不再被选中时,不要忘记删除识别器。

internal func mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView) {

    // Remove the gesture recognizer when the annotation is no longer selected.
}
