Can't render polygon (can't reserve indicies: XX): featureID: X key: XXXX
cocoa-touch, ios, mkmapview, objective-c
Solution
I also had the same output in my console on iOS 6.1.
In my case the problem was that I tried to zoom out the map based on a coordinate which was (0.00000,0.00000), and it created strange rendering problems only in the first time that I opened the map. after I re-opened the map it worked correctly. But when the coordinate wasn't (0.00000,0.00000), it always worked.
Maybe you should check that the value of `theCoordinate` is what you want it to be.
Problem
I have use Mac OS X 10.9.3 and Xcode 5.1.1 In my app I have to use `MKMapView`, It's all are working fine but in iOS 6.1, I have stranger error display in console, such like, ``` Can't render polygon (can't reserve indicies: 1482): featureID: 0 key: 0.0.1 (512) Can't render polygon (can't reserve indicies: 570): featureID: 0 key: 0.0.1 (512) Can't render polygon (can't reserve indicies: 30): featureID: 0 key: 0.0.1 (512) Can't render polygon (can't reserve indicies: 390): featureID: 0 key: 0.0.1 (512) Can't render polygon (can't reserve indicies: 330): featureID: 0 key: 0.0.1 (512) Can't render polygon (can't reserve indicies: 18): featureID: 0 key: 0.0.1 (512) Can't render polygon (can't reserve indicies: 30): featureID: 0 key: 0.0.1 (512) Can't render polygon (can't reserve indicies: 18): featureID: 0 key: 0.0.1 (512) ``` Like as a This question. I want to know about this error and why this is displaying in iOS 6.1 and how can I solve it? My code is: ``` self.mapView = [[MKMapView alloc] init]; self.mapView.frame = CGRectMake(30, 30, 140, 105); [self.mapView setMapType:MKMapTypeStandard]; [self.mapView setZoomEnabled:YES]; [self.mapView setScrollEnabled:YES]; [self.mapView setDelegate:self]; self.mapView.layer.borderWidth = 1; self.mapView.layer.borderColor = [UIColor lightGrayColor].CGColor; [self.scrollView addSubview:self.mapView]; self.pointAnnotation = [[MKPointAnnotation alloc] init]; [self setMAPAnnotationAndCallout]; /// custom method for set annotation pin and callout -(void)setMAPAnnotationAndCallout { CLLocationCoordinate2D theCoordinate ; theCoordinate.latitude = [[self.dicOfMAP objectForKey:@"latitude"] doubleValue]; theCoordinate.longitude = [[self.dicOfMAP objectForKey:@"longitude"] doubleValue]; self.pointAnnotation.coordinate = theCoordinate; self.pointAnnotation.title = @"Title"; self.pointAnnotation.subtitle = @"SubTitle"; int region = 8000; MKCoordinateRegion adjustedRegion = [self.mapView regionThatFits:MKCoordinateRegionMakeWithDistance(theCoordinate, region, region)]; [self.mapView setRegion:adjustedRegion animated:YES]; } #pragma mark - #pragma mark - MKMapView Delegate Methods - (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views { MKAnnotationView *aV; for (aV in views) { CGRect endFrame = aV.frame; aV.frame = CGRectMake(aV.frame.origin.x, aV.frame.origin.y - 230.0, aV.frame.size.width, aV.frame.size.height); [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.70]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [aV setFrame:endFrame]; [UIView commitAnimations]; } } - (MKAnnotationView *)mapView:(MKMapView *)sender viewForAnnotation:(id < MKAnnotation >)annotation { static NSString *reuseId = @"StandardPin"; MKPinAnnotationView *aView = (MKPinAnnotationView *)[sender dequeueReusableAnnotationViewWithIdentifier:reuseId]; if (aView == nil) { aView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:reuseId]; aView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; aView.canShowCallout = YES; } aView.annotation = annotation; return aView; } - (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view { [mapView deselectAnnotation:view.annotation animated:YES]; } ```
