    NSLog(@"Anchor enabled: %@", anchorEnabled ? @"YES" : @"NO");

isVisible

- (BOOL) isVisible

Returns true if user location layer is visible.

Swift code snippet:

        let visible = userLocationLayer.isVisible()
        print("User location layer is visible: \‍(visible)")

    BOOL visible = [_userLocationLayer isVisible];
    NSLog(@"User location layer is visible: %@", visible ? @"YES" : @"NO");

resetAnchor

- (void) resetAnchor

Resets anchor to default (center).

Swift code snippet:

        userLocationLayer.resetAnchor()
        print("Anchor reset to default")

        let anchor = ScreenPoint(x: 100.0, y: 200.0)
        userLocationLayer.setAnchor(anchor)
        print("Set user location anchor to: (\‍(anchor.x), \‍(anchor.y))")

Objective C code snippet:

    NCScreenPoint *anchor = [[NCScreenPoint alloc] initWithX:100.0f y:200.0f];
    [_userLocationLayer setAnchor:anchor];
    NSLog(@"Set user location anchor to: (%.1f, %.1f)", anchor.x, anchor.y);
