Question

我使用 Mac OS X 10.9.3 和 Xcode 5.1.1

在我的应用中，我必须使用MKMapView，它们都运行良好，但在iOS 6.1中，我在控制台中显示陌生人错误，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)

喜欢This question.

我想知道这个错误以及为什么会在iOS 6.1中显示这个错误，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];
}

    for (aV in views)

        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 setAnimationCurve:UIViewAnimationCurveEaseInOut];
        [aV setFrame:endFrame];
        [UIView commitAnimations];
    }
}

        aView.canShowCallout = YES;
    }
    aView.annotation = annotation;

    return aView;
}

{
    [mapView deselectAnnotation:view.annotation animated:YES];
}

我在iOS 6.1的控制台中也有相同的输出。

在我的情况下，问题是我试图根据坐标（0.00000,0.00000）缩小地图，并且仅在我第一次打开地图时才创建奇怪的渲染问题。 / strong>重新打开地图后，它正常工作。但是当坐标不是（0.00000,0.00000）时，它总是有效。

也许您应该检查theCoordinate的值是否是您想要的值。

无法渲染多边形（无法保留标记：XX）：featureID：X键：XXXX
