Question

SKRoutingService在计算之后是否有任何已知错误未放大到路由？

我的案例场景是下一个：我在一个视图控制器中有一个场地列表。当用户点击其中任何一个时，另一个ViewController将打开并在其上，将使用以下代码创建SKMapView的新实例：

-(void)initMap
{
_map = [[SKMapView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, _mapView.frame.size.height)];

//UIView* userInteractionBlocker = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, _mapView.frame.size.height)];
//[_mapView addSubview:userInteractionBlocker];

_map.settings.rotationEnabled = YES;
_map.settings.displayMode = SKMapDisplayMode2D;

_map.mapScaleView.hidden = YES;
//[map centerOnCurrentPosition];
//[map animateToZoomLevel:25.0];

[SKRoutingService sharedInstance].mapView = _map;
[SKRoutingService sharedInstance].routingDelegate = self;

SKRouteSettings* route = [[SKRouteSettings alloc]init];

route.startCoordinate=CLLocationCoordinate2DMake([Constants shared].selectedExit.lat, [Constants shared].selectedExit.lon);
route.destinationCoordinate=CLLocationCoordinate2DMake([Constants shared].selectedVenue.lat, [Constants shared].selectedVenue.lon);

UIImage *venuePin;
switch (_venue.primary_category) {
    case 626:
        venuePin = [UIImage imageNamed:@"pinGasBlack"];
        break;
    case 623:
        venuePin = [UIImage imageNamed:@"pinHotelBlack"];
        break;
    case 593:
        venuePin = [UIImage imageNamed:@"pinFoodYellow"];
        break;
}
SKAnnotation* exit = [self createPinWithImage:[UIImage imageNamed:@"pinExitYellow"] atCoordinates:CLLocationCoordinate2DMake([Constants shared].selectedExit.lat, [Constants shared].selectedExit.lon) withIdentifier:@"pinExit" identifier:0];
SKAnnotation* venue = [self createPinWithImage:venuePin atCoordinates:CLLocationCoordinate2DMake([Constants shared].selectedVenue.lat, [Constants shared].selectedVenue.lon) withIdentifier:@"pinVenue" identifier:1];

[_map addAnnotation:exit withAnimationSettings:nil];
[_map addAnnotation:venue withAnimationSettings:nil];

[_mapView addSubview:_map];

[[SKRoutingService sharedInstance] calculateRoute:route];
}

- (void)routingService:(SKRoutingService *)routingService didFinishRouteCalculationWithInfo:(SKRouteInformation*)routeInformation{
[[SKRoutingService sharedInstance] zoomToRouteWithInsets:UIEdgeInsetsZero];

}

事情是，我第一次打开场地屏幕，计算路线并完美地缩放。

但是一旦我回去，选择另一个场地并进入ViewController，其中应该初始化另一个新地图并缩放到路线位置，它不会发生。会发生什么： - 地图已初始化 - 计算路线 - 地图注释完美放置

但它缩小到显示行星地球......所以完全缩小，即使我设置

[[SKRoutingService sharedInstance] zoomToRouteWithInsets:UIEdgeInsetsZero];

我检查过，路由计算后代码是可以访问的，但它根本不会缩放？

对此有任何解决方案吗？

这是一个错误：两次致电zoomToRouteWithInsets

SKRoutingService在计算后没有缩放到路由
