ios - AnnotationView 在 calloutVIew 上重叠

我正在使用 MapKit 在 map 上显示数据。为此，我使用自定义 AnnotationView 和自定义 CalloutView。但问题是，当我让 AnnotationView 相互关闭时，AnnotationView 在 CalloutView 上重叠。这是问题的截图。

按钮也有问题，按钮的点击事件没有被调用。 calloutView 下方的 4 个按钮不会在点击时被调用。但是右上角代表编辑事件的按钮在点击时会被触发。

这是我的 CalloutView 代码。

@implementation CustomCalloutView

- (id)init {

        return self;
}
- (IBAction)btnEditActionUIButton *)sender {

    [self.delegate btnEditClicked];
}

- (IBAction)btnMailActionUIButton *)sender {

    [self.delegate btnMailClicked];
}

- (IBAction)btnMessageActionUIButton *)sender {

    [self.delegate btnMessageClicked];
}

- (IBAction)btnCallActionUIButton *)sender {

    [self.delegate btnCallClicked];

}

- (IBAction)btnStreetActionUIButton *)sender {

    [self.delegate btnStreetClicked];
}
- (IBAction)CalloutTapGestureClickedUITapGestureRecognizer*)sender {
    [self.delegate CalloutTApGesture:sender];
}
@end

请帮我解决这个问题...

这样做可以防止重叠(在顶部插入 callOut View )

 func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView)
 {

   print("clickedddddddd")

    if view.annotation is MKUserLocation
    {
        return
    }

        let customView = (Bundle.main.loadNibNamed("customSou", owner: self, options: nil))?[0] as! customSouOut;

        var calloutViewFrame = customView.frame;
        calloutViewFrame.origin = CGPoint(x:-calloutViewFrame.size.width/2 + 15,y: -calloutViewFrame.size.height);
        customView.frame = calloutViewFrame;


        view.addSubview(customView)


         // here you can fill any label or button with data according to it's pin 

         //

        for v in view.subviews
        {
            if v is customSouOut
            {
                continue
            }
            else
            {
                view.insertSubview(customView, aboveSubview: v)
            }
        }

    }

}

func mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView)
{
     print("oppspspspsps")

    if view.annotation is MKUserLocation
    {
        return
    }

     for v in view.subviews
    {
        if v is customSouOut 
        {
            v.removeFromSuperview()

            break
        }
    }
