用于 MKA 注释视图的自定义视图 Xib 按钮点击

Question

我正在制作一个自定义的MKAnnotationView，我在xib内部有一个按钮，我想在其中获取何时在内部进行修饰。

尽管存在具有相同问题的问题，但它们都无法使用我的代码。我有以下内容。

class CustomCalloutView: MKAnnotationView {
     var didTapGoButton: (() -> Void)?
    // MARK: - Detect taps on callout
    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
        let rect = self.bounds;
        var isInside: Bool = rect.contains(point);
        if(!isInside)
        {
            for view in self.subviews
            {
                isInside = view.frame.contains(point);
                if isInside
                {
                    break;
                }
            }
        }
        return isInside;
    }
    override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
        let hitView = super.hitTest(point, with: event)
        if (hitView != nil)
        {
            self.superview?.bringSubview(toFront: self)
        }
        return hitView
    }
    @IBAction func viewEventDetails(_ sender: Any) {
        didTapGoButton?()
    }
 func configureCell(events: Events) {
  eventName.text = events.eventName
 }
}

视图控制器

class EventAnnotation : MKPointAnnotation {
    var myEvent:Events?
}

    func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
        guard let annotation = view.annotation else { return }
        if view.annotation!.isKind(of: MKUserLocation.self){
            return
        }
         if let eventAnnotation = view.annotation as? EventAnnotation {
                    let theEvent = eventAnnotation.myEvent
                    let customView = (Bundle.main.loadNibNamed("CustomCalloutView", owner: self, options: nil))?[0] as! CustomCalloutView;
                    let calloutViewFrame = customView.frame;
                    customView.frame = CGRect(x: -calloutViewFrame.size.width/2.23, y: -calloutViewFrame.size.height-7, width: 315, height: 298)
                    customView.configureCell(events: theEvent!)
                    customView.didTapGoButton = { [weak mapView ] in
                        print(theEvent?.eventName ?? "noname")
                    }
                    view.addSubview(customView)
                }
    }

    func mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView)
    {
        for childView:AnyObject in view.subviews{
            childView.removeFromSuperview();
        }
    }

因此，当我点击按钮时，没有打印任何内容！

知道我在代码中的错误在哪里吗？

Answer 1

我解决了它，这个想法是将自定义视图定位在pinAnnotationView图像的边界中，因为它的任何点击外侧都将被视为didSelect方法调用，所以玩框架直到检测到点击，它将在自定义视图或视图控制器中工作

    customView.frame = CGRect(x: -calloutViewFrame.size.width/2.23, y: calloutViewFrame.size.height, width: 315, height: 298)

这是一个演示来说明情况
