ios - iOS - 无法获取标注中按钮的 DetailDisclosure

Question

我在 iOS 9 中使用 Swift。无论我选择什么按钮类型，除了 ContactAdd，只会呈现信息图标。我正在尝试在地图视图中获取标注右侧的 DetailDisclosure 图标。这是代码：

    let rightButton = UIButton(type: UIButtonType.DetailDisclosure);
    rightButton.addTarget(self, action: "buttonTapped:", forControlEvents: UIControlEvents.TouchUpInside)
    annotationView.rightCalloutAccessoryView = rightButton;

Answer 1

你创建了一个图钉吗？尝试将按钮添加.DetailDisclosure到pinView

var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? 
pinView!.rightCalloutAccessoryView = UIButton.buttonWithType(.DetailDisclosure) as UIButton

更新 这对我有用

let identifier = "pin"
var view: MKPinAnnotationView
view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
view.canShowCallout = true
view.calloutOffset = CGPoint(x: -5, y: 5)
view.rightCalloutAccessoryView = UIButton(type: .DetailDisclosure) as UIView

@user2893289
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView?
 {
    let annotationView = MKPinAnnotationView(annotation: noseyesAnnotation, reuseIdentifier: "pin")
    annotationView.pinTintColor = noseyesAnnotation.color
    annotationView.canShowCallout = true
    let rightButton = UIButton(type: UIButtonType.DetailDisclosure);
    annotationView.rightCalloutAccessoryView = rightButton;
    return annotationView
}
