我目前有一个UIMapView，其中有不同的注释，用于地图上用户的不同位置。单击注释时，我试图切换到相应的用户配置文件。这是我设置注释的代码：
let query = PFQuery(className: "location")
query.findObjectsInBackground { (objects, error) in
if let brandsLocation = objects {
for object in brandsLocation {
if let brandLocation = object as? PFObject {
let annotation = MKPointAnnotation()
let annotationPoint = object["geoPoint"] as! PFGeoPoint
annotation.coordinate = CLLocationCoordinate2DMake(annotationPoint.latitude, annotationPoint.longitude)
annotation.title = brandLocation["annotationTitle"] as? String
annotation.subtitle = brandLocation["annotationSubtitle"] as? String
self.map.addAnnotation(annotation)
}
}
}
}
这是我认为segue应该发生的地方，但是由于某些原因它没有做任何事情。
// When user taps on the disclosure button you can perform a segue
to navigate to another view controller
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView,
calloutAccessoryControlTapped control: UIControl) {
if control == view.rightCalloutAccessoryView{
performSegue(withIdentifier: "goToUserProfile", sender: view)
print(view.annotation?.title) // annotation's title
print(view.annotation?.subtitle) // annotation's subttitle
//Perform a segue here to navigate to another viewcontroller
// On tapping the disclosure button you will get here
}
}
// Here we add disclosure button inside annotation window
func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
print("viewForannotation")
if annotation is MKUserLocation {
//return nil
return nil
}
let reuseId = "pin"
var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView
if pinView == nil {
//println("Pinview was nil")
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
pinView!.canShowCallout = true
pinView!.animatesDrop = true
}
let button = UIButton(type: UIButtonType.detailDisclosure) as UIButton // button with info sign in it
pinView?.rightCalloutAccessoryView = button
return pinView
}
我想在单击或双击注释时发生segue，然后在发送特定用户名信息时对新视图控制器执行segue。我很确定我能够发送用户信息，但我只需要弄清楚如何使segue发生。任何帮助深表感谢！谢谢
更新问题可能是我的CalloutAccessory未显示。当我点击我的应用中的图钉时，请查看此屏幕截图：
