Paths disappear at high zoom levels about route-me HOT 7 CLOSED

Hm, I never had issues with vanishing paths, and I use them a lot. Can you create a demo project that shows the issue?

from route-me.

FYI, it actually doesn't seem like a bug because the paths are between points that are far apart (100+ miles) and once you zoom in the associated annotations would be "hidden"... So, the behavior actually makes sense, but I need a way to show paths between two waypoints that are far apart at high zoom levels. So, any thoughts on how to create a static path between two points would be great!
Thanks!
p.s. I can whip up a working demo to try and flesh this functionality out if need be.

A small demo would be great, so that I have something to play with. Since our products are fairly complicated and use most of the route-me functionality, I might know some not-so-obvious solution to this problem.

BTW if you want an annotation to never be hidden, then you could also set the whole world as the bounding box for the annotation:

- (void)setBoundingBoxCoordinatesSouthWest:(CLLocationCoordinate2D)southWest northEast:(CLLocationCoordinate2D)northEast

Sounds good. I'll work on a demo later today and get it up. Also, your bounding box suggestion might be a perfect solution. I'm guessing if I drew a path between two far points and set the bounding box to be each point that would probably solve my disappearing route problem?

Ah, now I see your problem. This is actually badly documented, I have to admit. You have to set the path bounding box for the annotation and the map view will do the rest. In my code, it looks like this (in a RMMapView category):

- (void)addPolyline:(NSArray *)linePoints withLineColor:(UIColor *)lineColor
{
    if ([linePoints count] < 2) return;

    linePoints = [GeoUtils reduceNumberOfCoordinates:linePoints to:900];

    RMAnnotation *polylineAnnotation = [RMAnnotation annotationWithMapView:self coordinate:((CLLocation *)[linePoints firstObject]).coordinate andTitle:nil];
    polylineAnnotation.annotationType = @"polyline";
    polylineAnnotation.userInfo = [NSDictionary dictionaryWithObjectsAndKeys:linePoints,@"linePoints", lineColor,@"lineColor", nil];
    [polylineAnnotation setBoundingBoxFromLocations:linePoints];

    [self addAnnotation:polylineAnnotation];
}

linePoints is an array of CLLocations. So, setting the bounding box to the two endpoints should do the trick.

I think I should make this more evident...

Setting the bounding box worked perfectly, thank you! I'm going to try and implement the rest of the various items using annotations and see how that plays out before trying to implement static layers.

Thanks again!
