使用Skobbler开始导航后，在c ++。字符串文件中的EXC_BAD_ACCESS

Question

在我更新了我的项目并介绍了Pods之后，我有这个奇怪的错误，只有当我想在路由上开始导航后才能成功计算它。

这是我收到错误的地方，我不知道它是如何实现的，因为我没有对我的代码进行任何重大更改，除了通过CocoaPods在我的项目中使用SKMaps而不是手动拖动它

老实说，我不知道这个文件到底是什么，我不知道为什么会出现这个错误。

这是我用来生成SKMap，创建路线，显示它的代码（直到这一部分，一切正常），但是当我想在计算出的路线上开始导航时，我收到错误

-(void)initMap
{
SKMapView *mapView = [[SKMapView alloc] initWithFrame:CGRectMake( 0.0f, 0.0f,  CGRectGetWidth(self.view.frame), CGRectGetHeight(self.view.frame) )];


[self.view addSubview:mapView];

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

SKRouteSettings* route = [[SKRouteSettings alloc]init];
route.startCoordinate=![CLLocationCoordinate2DMake][1](39.263671, -103.642420);
route.destinationCoordinate=CLLocationCoordinate2DMake(39.782730, -104.908250);
route.shouldBeRendered = YES; // If NO, the route will not be rendered.
route.numberOfRoutes = 1;
[[SKRoutingService sharedInstance] calculateRoute:route];
}
- (void)routingService:(SKRoutingService *)routingService didFinishRouteCalculationWithInfo:(SKRouteInformation*)routeInformation{
NSLog(@"Route is calculated.");
[routingService zoomToRouteWithInsets:UIEdgeInsetsZero]; // zoom to current route

SKNavigationSettings* navSettings = [SKNavigationSettings navigationSettings];
navSettings.navigationType=SKNavigationTypeSimulation;
navSettings.distanceFormat=SKDistanceFormatMilesFeet;
navSettings.zoomLevelConfigurations = nil;

[SKRoutingService sharedInstance].mapView.settings.displayMode = SKMapDisplayMode3D;
[[SKRoutingService sharedInstance]startNavigationWithSettings:navSettings]; //THIS IS THE LINE THAT TRIGGERS AN ERROR
}
- (void)routingServiceDidFailRouteCalculation:(SKRoutingService *)routingService{
NSLog(@"Route calculation failed.");
}

编辑：主要问题是我无法获得任何堆栈跟踪。这就是全部，我设置了断点来显示所有异常。 这是我收到错误时Xcode屏幕的屏幕截图，而且全部都是：
