MKMapView的Swift自定义标注

我正在为mapview实现自定义标注视图.我得到了这个输出

对于我正在使用的注释视图

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
}

并弹出标注视图

func mapView(mapView: MKMapView!,didSelectAnnotationView view: MKAnnotationView!){
    var viewC:UIView=UIView(frame: CGRectMake(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)


}

解决方法

我得到了解决方案它的变化非常小.在viewForAnnotation中隐藏基本标注如下,

anView!.canShowCallout = false
