如何更改Annotation標註窗口的高度Swift

Question

如何在Swift中更改Map上Annotation標註窗口的大小。我試圖在右側和左側視圖的每個組件上製作更大的CGSize，但沒有任何成功。最終視圖的高度仍然相同。

這裏是我的代碼：

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? { 

    print("delegate called") 

    if !(annotation is CustomPointAnnotation) { 
     return nil 
    } 

    let reuseId = "test" 

    var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) 
    if anView == nil { 
     anView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId) 


     selectedUstanova = (annotation as! CustomPointAnnotation).ustanova 


     anView!.canShowCallout = true 
    } 
    else { 
     anView!.annotation = annotation 
    } 

    //Set annotation-specific properties **AFTER** 
    //the view is dequeued or created... 

    let cpa = annotation as! CustomPointAnnotation 
    anView!.image = UIImage(named:cpa.imageName) 
    return anView 
} 
func mapView(mapView: MKMapView, didSelectAnnotationView view: MKAnnotationView) 
{ 
    let button : UIButton = UIButton(type: UIButtonType.Custom) as UIButton 
    let image = UIImage(named: "telephone") 
    button.layer.cornerRadius = 10 
    button.layer.backgroundColor = UIColor.whiteColor().CGColor 
    button.layer.masksToBounds = true 
    button.setBackgroundImage(image, forState: UIControlState.Normal) 
    button.frame = CGRectMake(0, 0, 35, 200) 
    button.addTarget(self, action: "buttonClicked:", forControlEvents: UIControlEvents.TouchUpInside) 


    let labelTitle : UILabel = UILabel(frame: CGRectMake(20,0,150,50)) 
    labelTitle.text = selectedUstanova!.ime 
    let labelSubTitle : UILabel = UILabel(frame: CGRectMake(20,50,150,100)) 
    var ustanovaOpis = "" 
    if selectedUstanova!.opis != nil{ 
     ustanovaOpis+=selectedUstanova!.opis!+"\n" 
    } 
    if selectedUstanova!.telefon != nil{ 
     ustanovaOpis+=selectedUstanova!.telefon! 
    } 
    labelSubTitle.text = ustanovaOpis 
    let leftCAV : UIView = UIView(frame: CGRectMake(0,0,250,250)); 
    let leftCAV2: UIView = UIView(frame: CGRectMake(0,0,250,250)); 
    let imageB = UIImage(named: "bigbutton") 
    let imageView : UIImageView = UIImageView(frame: CGRectMake(0,0,300,300)) 
    imageView.image = imageB; 
    leftCAV.addSubview(imageView) 
    leftCAV.addSubview(labelTitle) 
    leftCAV.addSubview(labelSubTitle) 
    view.leftCalloutAccessoryView = leftCAV; 
    view.rightCalloutAccessoryView = leftCAV2; 
} 

有沒有做更大的查看我試圖改變左右標註附屬視圖，但沒有成功迄今規模的機會。

如果您只是想更改註釋標註的高度，這裏是簡單的方法。而我只是把身高提高到200個單位。

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? { 
    if annotation is MKUserLocation { 
     return nil 
    } 
    let reuseID = "pin" 
    var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseID) as? MKPinAnnotationView 
    if pinView == nil { 
     pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseID) 
     pinView!.canShowCallout = true 
     pinView!.animatesDrop = true 
     pinView!.pinTintColor = UIColor.blackColor() 
    } 
    pinView!.detailCalloutAccessoryView = self.configureDetailView(pinView!) 
    return pinView 
} 

func configureDetailView(annotationView: MKAnnotationView) -> UIView { 
    let snapshotView = UIView() 
    let views = ["snapshotView": snapshotView] 
    snapshotView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[snapshotView(200)]", options: [], metrics: nil, views: views)) 
    //do your work 
    return snapshotView 
}
