如何在Mapbox上更改rightCalloutAccessory的色调？

Question

有没有办法更改注释rightCalloutAccessory的色调颜色，而不更改mapView的色调？

例如，我想将地图色调颜色设置为白色，以便用户当前位置和右下角的信息图标为白色，但我想要注释{{1}成为蓝色。

Answer 1

您需要mapView:rightCalloutAccessoryViewForAnnotation:，可以这样使用：

- (UIView *)mapView:(__unused MGLMapView *)mapView rightCalloutAccessoryViewForAnnotation:(__unused id<MGLAnnotation>)annotation
{
    UIButton *rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeInfoLight];
    rightCalloutAccessoryView.tintColor = [UIColor blueColor];

    return rightCalloutAccessoryView;
}

Answer 2

我认为您想要更改注释视图的色调颜色。您可以通过调用MKMapViewDelegate协议的功能来执行此操作：

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
    var annotationView = mapView.dequeueReusableAnnotationViewWithIdentifier("annotationView") as? MKPinAnnotationView

    if annotationView == nil {
        annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "annotationView")
    }

    annotationView?.canShowCallout = true
    annotationView?.rightCalloutAccessoryView = UIButton(type: UIButtonType.DetailDisclosure)
    annotationView?.rightCalloutAccessoryView?.tintColor = UIColor.whiteColor()

    return annotationView
}
