CLLocationManager EXC_BAD_INSTRUCTION

Question

我在我的应用中使用logWithContext，并使用public class RequestIdFilter implements WebFilter { private Logger LOG = LoggerFactory.getLogger(RequestIdFilter.class); @Override public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) { HttpHeaders headers = exchange.getRequest().getHeaders(); return chain.filter(exchange) .doAfterSuccessOrError((r, t) -> logWithContext(headers, httpHeaders -> LOG.info("Some message with MDC set"))) .subscriberContext(Context.of(HttpHeaders.class, headers)); } static void logWithContext(HttpHeaders headers, Consumer<HttpHeaders> logAction) { try { headers.forEach((name, values) -> MDC.put(name, values.get(0))); logAction.accept(headers); } finally { headers.keySet().forEach(MDC::remove); } } } 正确设置了GoogleMaps，Info.plist中的所有内容

EXC_BAD_INSTRUCTION

即使我设置正确。这是下面的代码。

locationManager...didChangeAuthorization

这是我的locationManager代表

requestWhenInUseAuthorization

注意：似乎我两次要求locationManager.requestWhenInUseAuthorization() locationManager.startUpdatingLocation() let camera = GMSCameraPosition.camera(withTarget: (self.locationManager.location?.coordinate)!, zoom: zoomLevel) self.mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera) self.view = self.mapView self.initializeTheLocationManager() self.mapView.isMyLocationEnabled = true 。

Answer 1

这不起作用。

startUpdatingLocation 异步工作。您必须实现didUpdateLocations。

    locationManager.requestWhenInUseAuthorization()
    locationManager.startUpdatingLocation()
}

...

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let camera = GMSCameraPosition.camera(withTarget: (locations[0].coordinate, zoom: zoomLevel)
    self.locationManager.stopUpdatingLocation()
    self.mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
    self.view = self.mapView
    self.initializeTheLocationManager()
    self.mapView.isMyLocationEnabled = true
}
