我有自定义注释，它的 calloutbubble 有表格所在的视图，高度为 200。
但是在标注气泡中设置它不会影响标注气泡的大小
我怎么能做到这一点？
这是我的代码

-(MKAnnotationView *)mapView:(MKMapView *)mapView1 viewForAnnotation:(id<MKAnnotation>)annotation
{
     if([annotation isKindOfClass:[CustomAnnotation class]])
    {
        CustomAnnotation *location = (CustomAnnotation *)annotation;
        MKAnnotationView   *annotation_View = [mapView1 dequeueReusableAnnotationViewWithIdentifier:@"customAnnotation"];
        if (annotation_View == nil)
        {
            annotation_View = location.annotationView;
            if ([location.title isEqualToString:@"My Spot"])
            {
                annotation_View.image = [UIImage imageNamed:@"orange.png"];
            }
            else
            {
                annotation_View.image=[UIImage imageNamed:@"ocean.png"];
            }
        }
        else
        {
            annotation_View.annotation = annotation;
        }
        [self configureDetailView:annotation_View];
        return annotation_View;
    }
    return nil;
}

-(void)configureDetailView : (MKAnnotationView*)annotationView1
{
    self.AnnotationViewForDetail.frame = CGRectMake(0, 0, 100, 200);
    annotationView1.detailCalloutAccessoryView = self.AnnotationViewForDetail;
}

请参考这个答案。

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
    static NSString *identifier = @"MyAnnotationView";

if ([annotation isKindOfClass:[MKUserLocation class]]) {
    return nil;
}

MKPinAnnotationView *view = (id)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (view) {
    view.annotation = annotation;
} else {
    view = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
    view.canShowCallout = true;
    view.animatesDrop = true;
}
view.detailCalloutAccessoryView = [self detailViewForAnnotation:annotation];

return view;
}

- (UIView *)detailViewForAnnotation:(PlacemarkAnnotation *)annotation {
    UIView *view = [[UIView alloc] init];
    view.translatesAutoresizingMaskIntoConstraints = false;

    UILabel *label = [[UILabel alloc] init];
    label.text = annotation.placemark.name;
    label.font = [UIFont systemFontOfSize:20];
    label.translatesAutoresizingMaskIntoConstraints = false;
    label.numberOfLines = 0;
    [view addSubview:label];

    UIButton *button = [self yesButton];
    [view addSubview:button];

    NSDictionary *views = NSDictionaryOfVariableBindings(label, button);

    [view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[label]|" options:0 metrics:nil views:views]];
    [view addConstraint:[NSLayoutConstraint constraintWithItem:button attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:view attribute:NSLayoutAttributeCenterX multiplier:1 constant:0]];
    [view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[label]-[button]|" options:0 metrics:nil views:views]];

    return view;
}

- (UIButton *)yesButton {
    UIImage *image = [self yesButtonImage];

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    button.translatesAutoresizingMaskIntoConstraints = false; // use auto layout in this case
    [button setImage:image forState:UIControlStateNormal];
    [button addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventPrimaryActionTriggered];

    return button;
}
