当我只点击注释视图和
this behavior it’s right时,我的calloutAccessoryControlTapped也被调用.但是如何检测用户是否在右侧的附件视图(在我的例子中是详细的公开按钮),而不仅仅是在视图中？
我添加了一个简单的检查,但它不工作.
import UIKit
import MapKit
extension MapVC: MKMapViewDelegate,CLLocationManagerDelegate
{
func mapView(mapView: MKMapView,annotationView view: MKAnnotationView,calloutAccessoryControlTapped control: UIControl)
{
if control == view.rightCalloutAccessoryView
{
... // enter here even if I tapped on the view annotation and not on button
}
}
}
解决方法
要实现它,您需要添加正确的配件视图的目标.您可以通过将代码片段中所示的按钮设置为rightCalloutAccessoryView来实现.
class MapViewController: UIViewController,MKMapViewDelegate {
func mapView(mapView: MKMapView,viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if annotation is Annotation {
let annotationView = AnnotationView(annotation: annotation,reuseIdentifier: "reuseIdentifier")
let rightButton = UIButton(type: .DetailDisclosure)
rightButton.addTarget(self,action: #selector(didClickDetailDisclosure(_:)),forControlEvents: .TouchUpInside)
annotationView.rightCalloutAccessoryView = rightButton
}
return nil
}
func didClickDetailDisclosure(button: UIButton) {
// TODO: Perform action when was clicked on right callout accessory view.
}
}
// Helper classes.
class Annotation: NSObject,MKAnnotation {
var coordinate: CLLocationCoordinate2D
var title: String?
var subtitle: String?
init(coordinate: CLLocationCoordinate2D,title: String,subtitle: String) {
self.coordinate = coordinate
self.title = title
self.subtitle = subtitle
}
}
class AnnotationView: MKAnnotationView {
}
