无法呈现多边形（无法保留指示：XX）：featureID：X key：XXXX
我已经使用Mac OS X 10.9.3和Xcode 5.1.1
在我的应用程序，我必须使用MKMapView ，这一切都工作正常，但在iOS 6.1中，我有更奇怪的错误显示在控制台，
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)
就像这个问题一样。
我想知道这个错误，为什么这是显示在iOS 6.1中，我该如何解决？
我的代码是：
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]; }
我在iOS 6.1的控制台上也有相同的输出。
在我的情况下，问题是我试图缩小基于（0.00000,0.00000）的坐标的地图，它只是在我第一次打开地图时，创build了奇怪的渲染问题。 我重新打开地图后正常工作。 但是当坐标不是（0.00000,0.00000）时，它一直工作。
也许你应该检查theCoordinate的价值是你想要的。
