我有用Mac OS X 10.9.3 and Xcode 5.1.1
在我的应用程序中我必须使用MKMapView
,一切都工作正常,但在 iOS 6.1 中,我在控制台中显示了奇怪的错误,例如,
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)
就像作为这个问题。 https://stackoverflow.com/questions/16943146/strange-error-cant-render-polygon
我想了解此错误以及为什么在 iOS 6.1 中显示此错误以及如何解决它?
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];
}
