我正在爲mapview實現自定義標註視圖。我得到這個輸出MKMapView的Swift自定義標註
對於註解視圖我使用
func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
let reuseId = "mapPin"
var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? CustomCalloutView
if anView == nil {
anView=CustomCalloutView(annotation: annotation,reuseIdentifier:reuseId)
anView!.image = UIImage(named:"mappin.png")
let button : UIButton = UIButton.buttonWithType(UIButtonType.DetailDisclosure) as! UIButton
button.addTarget(self, action: "buttonClicked:", forControlEvents: UIControlEvents.TouchUpInside)
anView!.rightCalloutAccessoryView=button
//anView!.addSubview(viewC)
mapViewControl.addAnnotation(annotation)
}
else {
anView!.annotation = annotation
}
return anView
}
,並彈出標註視圖
func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKAnnotationView!){
var viewC:UIView=UIView(frame: CGRectMake(0, 0, 50, 50))
viewC.backgroundColor = UIColor.blackColor()
view.addSubview(viewC)
viewC.center = CGPointMake(viewC.bounds.size.width*0.1, -viewC.bounds.size.height*0.5)
}
爲什麼有downvote? – Poonam
我沒有downvote,但也許這是因爲你沒有說明問題是什麼。順便說一下:在viewForAnnotation中,你爲什麼要調用addAnnotation - 這沒有任何意義。另外,使用calloutAccessoryControlTapped委託方法代替rightCalloutAccessoryView的addTarget。 – Anna
下一次更直接與您的問題。但這實際上是一個很好的實現:) – Michael
