如何使用RMShape显示路径？

我想做现场跟踪和绘制旅行线。

- (RMMapLayer *)mapView:(RMMapView *)mapView layerForAnnotation:(KRRMAnnotation *)annotation
{
    if (annotation.isUserLocationAnnotation)
        return nil;

    KRCalloutView *calloutView = [[[UINib nibWithNibName:@"KRRMCalloutView" bundle:nil] instantiateWithOwner:self options:nil] lastObject];
    calloutView.maxTitleLabelWidth = 250.0f;
    [calloutView setTitle:annotation.placeModel.title withAttributes:[KRStyleUtilities mapViewCalloutTextAttributes]];

    KRRMMarker *marker = [[KRRMMarker alloc]initWithUIImage:annotation.placeModel.pinImage andContentView:calloutView inMapView:mapView];
    marker.delegate = self.markerDelegateHandler;
    marker.cornerRadius = 10.0f;
    marker.correctCalloutPositionEnabled = YES;
    marker.canShowCallout = NO;

    return marker;
}

您可以删除并重新添加注释，强制重绘注释图层，也可以查看此修补程序，以便调用图层重绘：
