如何在
Swift中更改Map上的注释标注窗口的大小.我尝试在右视图和左视图的每个组件上创建一个更大的CGSize但没有任何成功最终视图的高度仍然是相同的.
这是我的代码：
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(0,35,200)
button.addTarget(self,action: "buttonClicked:",forControlEvents: UIControlEvents.TouchUpInside)
let labelTitle : UILabel = UILabel(frame: CGRectMake(20,150,50))
labelTitle.text = selectedUstanova!.ime
let labelSubTitle : UILabel = UILabel(frame: CGRectMake(20,50,100))
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(0,250,250));
let leftCAV2: UIView = UIView(frame: CGRectMake(0,250));
let imageB = UIImage(named: "bigbutton")
let imageView : UIImageView = UIImageView(frame: CGRectMake(0,300,300))
imageView.image = imageB;
leftCAV.addSubview(imageView)
leftCAV.addSubview(labelTitle)
leftCAV.addSubview(labelSubTitle)
view.leftCalloutAccessoryView = leftCAV;
view.rightCalloutAccessoryView = leftCAV2;
}
是否有机会使View更大我尝试改变左右标注配件视图的尺寸但到目前为止没有成功.
解决方法
如果您只对更改注释标注的高度感兴趣,这是一种简单的方法.我只是将高度提高到200个单位.
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
}
