Question

在我的应用程序中，我有一张地图的表格视图。当我快速滚动或导航视图控制器时，应用程序崩溃与segmentationFault 11.我在Nib中创建了mapview。这是cellforRowAtIndexPath中的代码部分，

    MKCoordinateRegion region ={ {0.0, 0.0 }, { 0.0, 0.0 } };
    CLLocationCoordinate2D  locationCoord=CLLocationCoordinate2DMake(item.locationLatitude,item.locationLongitude);

     region.center=locationCoord;
     MKCoordinateSpan span;
     span.latitudeDelta = 0.02;
     span.longitudeDelta = 0.02;
     region.span=span;
     XMapAnnotation *annotation = [[XMapAnnotation alloc] init];
     annotation.coordinate = locationCoord;
     annotation.title=@"xyz";
     [cell.mapView setRegion:region animated:NO];
     [cell.mapView addAnnotation:annotation];

在控制台中收到此错误： - [VKTileKeyList containsKey：]：发送到解除分配的实例0x193c78b0的消息。
