通过点击我的地图视图控制器中地图注释的信息按钮,我已经研究了这个主题近三天,试图找出如何呈现我的详细视图控制器。基本上,我可以获得要显示的注释,但是当我单击注释时,没有任何反应。我想让它呈现我的详细视图控制器,就像在我的表视图控制器中单击相同项目时一样,它直接进入其各自的详细视图。
任何帮助都会非常多,非常感谢! This is the image of the map annotation I currently have
下面是我的MapViewController的代码。我觉得我的prepareForSegue或annotationView函数中有错误或缺少某些东西。
extension MapViewController {
// 1
@objc(mapView:viewForAnnotation:) func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if let annotation = annotation as? Annotations {
let reuseID = "pin"
var view: MKPinAnnotationView
if let dequeuedView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseID)
as? MKPinAnnotationView { // 2
dequeuedView.annotation = annotation
view = dequeuedView
} else {
// 3
view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseID)
view.canShowCallout = true
view.isUserInteractionEnabled = true
view.calloutOffset = CGPoint(x: -5, y: 5)
view.rightCalloutAccessoryView = UIButton.init(type: .detailDisclosure) as UIButton
}
return view
}
return nil
}
func mapView(mapView: MKMapView, annotationView view: MKAnnotationView!, calloutAccessoryControlTapped control: UIControl!) {
if control == view.rightCalloutAccessoryView {
print(view.annotation?.title)
performSegue(withIdentifier: "moreDetail", sender: self)
}
}
func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "moreDetail") {
// pass data to next view
let destViewController:PancakeHouseViewController = segue.destination as! PancakeHouseViewController
destViewController.viaSegue = sender as! MKAnnotationView
}
}
}
我还在我的详细视图控制器(PancakeHouseViewController)中包含了一个变量...我不知道它是否应该在那里。
var viaSegue = MKAnnotationView()
答案 0 :(得分:0)
我认为问题可能出在calloutAccessoryControlTapped
的方法签名中。它应该是:
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl)
