How to delete a polyline in Mapbox iOS SDK?

I can do it in Google Maps by using 

polyline.map = nil

and 

mapView.clear()

but I cannot find any relevant methods.

Here is a category extension method for MGLMapView that I am using. Its just like Google Maps SDK, so its easier to use anywhere in your project.

- (void)clear {
    if (self.annotations.count > 0) {
        NSArray *annotations = self.annotations;
        [self removeAnnotations:annotations];
    }
}

You can use it like

[self.mapView clear];

You can call mapView.removeAnnotation(polyline)

Where mapView is your MGLMapView and polyline is a MGLPolyline.

You will probably need to keep track of your polylines, how you do that is up to you (array, dictionary, etc)

Here is the documentation for MGLMapView if you need it
