自定义iOS8标注泡沫(Swift)

1. Create custom MKAnnotationView or MAPinAnnotationView
2. Override setSELEcted and hitTest methods in your Annotation
3. Create your own callout view
4. Override hitTest and poinTinside in you callout view
5. Implement MapView delegate methods didSELEctAnnotationView,didDeSELEctAnnotationView

我已经结束了这些解决方案,允许我处理标注视图中的触摸,而不会丢失选择.

注解

class MapPin: MKAnnotationView {
    class var reusEIDentifier:string {
        return "mapPin"
    }

    private var calloutView:MapPinCallout?
    private var hitOutside:Bool = true

    var preventDeSELEction:Bool {
        return !hitOutside
    }


    convenience init(Annotation:MKAnnotation!) {
        self.init(Annotation: Annotation,reusEIDentifier: MapPin.reusEIDentifier)

        canShowCallout = false;
    }

    override func setSELEcted(SELEcted: Bool,animated: Bool) {
        let calloutViewAdded = calloutView?.superview != nil

        if (SELEcted || !SELEcted && hitOutsidE) {
            super.setSELEcted(SELEcted,animated: animated)
        }

        self.superview?.bringSubviewToFront(self)

        if (calloutView == nil) {
            calloutView = MapPinCallout()
        }

        if (self.SELEcted && !calloutViewAdded) {
            addSubview(calloutView!)
        }

        if (!self.SELEcted) {
            calloutView?.removeFromSuperview()
        }
    }

    override func hitTest(point: CGPoint,withEvent event: UIEvent?) -> UIView? {
        var hitView = super.hitTest(point,withEvent: event)

        if let callout = calloutView {
            if (hitView == nil && self.SELEcted) {
                hitView = callout.hitTest(point,withEvent: event)
            }
        }

        hitOutside = hitView == nil

        return hitView;
    }
}

标注视图

class MapPinCallout: UIView {
    override func hitTest(var point: CGPoint,withEvent event: UIEvent?) -> UIView? {
        let viewPoint = superview?.convertPoint(point,toView: self) ?? point

        let isInsideView = poinTinside(viewPoint,withEvent: event)

        var view = super.hitTest(viewPoint,withEvent: event)

        return view
    }

    override func poinTinside(point: CGPoint,withEvent event: UIEvent?) -> Bool {
        return CGRectContainsPoint(bounds,point)
    }
}

如果您需要其他东西,但按钮可以在标注中添加代码,以在hitTest返回视图之前处理特定视图中的触摸

if calloutState == .Expanded && CGRectContainsPoint(tableView.frame,viewPoint) {
    view = tableView.hitTest(convertPoint(viewPoint,toView: tableView),withEvent: event)
}

委托方法

func mapView(mapView: MKMapView!,didSELEctAnnotationView view: MKAnnotationView!) {
    if let mapPin = view as? MapPin {
        updatePinPosition(mapPin)
    }
}

func mapView(mapView: MKMapView!,didDeSELEctAnnotationView view: MKAnnotationView!) {
    if let mapPin = view as? MapPin {
        if mapPin.preventDeSELEction {
            mapView.SELEctAnnotation(view.Annotation,animated: falsE)
        }
    }
}

func updatePinPosition(pin:MapPin) {
    let defaultShift:CGFloat = 50
    let pinPosition = CGPointMake(pin.frame.midX,pin.frame.maxY)

    let y = pinPosition.y - defaultShift

    let controlPoint = CGPointMake(pinPosition.x,y)
    let controlPointCoordinate = mapView.convertPoint(controlPoint,toCoordinateFromView: mapView)

    mapView.setCenterCoordinate(controlPointCoordinate,animated: truE)
}
