copied!<p>I saw your issue <a href="https://code.google.com/p/gmaps-api-issues/issues/detail?id=5107&q=visibleRegion&colspec=ID%20Type%20Status%20Introduced%20Fixed%20Summary%20Stars%20ApiType%20Internal" rel="noreferrer">here</a>. Hope that they fix this issue in next update.</p> <p>But now we can take the real visible region like this:</p> <pre><code> CGPoint topLeftPoint = CGPointMake(0, 0); CLLocationCoordinate2D topLeftLocation = [_mapView.projection coordinateForPoint: topLeftPoint]; CGPoint bottomRightPoint = CGPointMake(_mapView.frame.size.width, _mapView.frame.size.height); CLLocationCoordinate2D bottomRightLocation = [_mapView.projection coordinateForPoint: bottomRightPoint]; CGPoint topRightPoint = CGPointMake(_mapView.frame.size.width, 0); CLLocationCoordinate2D topRightLocation = [_mapView.projection coordinateForPoint: topRightPoint]; CGPoint bottomLeftPoint = CGPointMake(0, _mapView.frame.size.height); CLLocationCoordinate2D bottomLeftLocation = [_mapView.projection coordinateForPoint: bottomLeftPoint]; GMSVisibleRegion realVisibleRegion; realVisibleRegion.farLeft = topLeftLocation; realVisibleRegion.farRight = topRightLocation; realVisibleRegion.nearLeft = bottomLeftLocation; realVisibleRegion.nearRight = bottomRightLocation; [self drawPolylineWithGMSVisibleRegion:realVisibleRegion color:[UIColor redColor] width:10.0f forMap:mapView]; </code></pre> <p>Drawing polyline method:</p> <pre><code>- (void)drawPolylineWithGMSVisibleRegion:(GMSVisibleRegion)visibleRegion color:(UIColor*)color width:(double)width forMap:(GMSMapView*)mapView{ GMSPolylineOptions *rectangle = [GMSPolylineOptions options]; rectangle.color = color; rectangle.width = width; GMSMutablePath *path = [GMSMutablePath path]; [path addCoordinate:visibleRegion.nearRight]; [path addCoordinate:visibleRegion.nearLeft]; [path addCoordinate:visibleRegion.farLeft]; [path addCoordinate:visibleRegion.farRight]; [path addCoordinate:visibleRegion.nearRight]; rectangle.path = path; [mapView addPolylineWithOptions:rectangle]; } </code></pre> <p>It works even for map with non-default bearing and angle.</p>
