Hi All,

I am new iPhone developer and really looking for help on following issue I am stuck with. Any help would be appreciated.

I am trying to create overlay of set of rectangles to stack them on one another. I have required coordinates. I know how to create the polyline view and bound them by MapRect to make it visible on loadview.

Code:
// the data representing the route. 
MKPolyline* _route;
MKPolylineView* _routeView;

// Following lines create polyline for my coordinateArray, add into overlay, and make it visible on map
self.route = [MKPolyline polylineWithCoordinates:coordinateArray count:points.count];
[self.mapView addOverlay:self.route];
[self.mapView setVisibleMapRect:[self.route boundingMapRect]];
     

- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id <MKOverlay>)overlay
{          
    if ([overlay isKindOfClass:[MKPolyline class]])
    {
     self.routeView = [[[MKPolylineView alloc] initWithPolyline:self.route] autorelease];
     self.routeView.fillColor = [UIColor redColor];
     self.routeView.strokeColor = [UIColor redColor];
     self.routeView.lineWidth = 8;
     return self.routeView;
    }
    return nil;
}

Now I want to convert all my coordinates into set of rectangles and bound them by the outer rectangle. Could anyone please help me on this.

Thanks in advance.
