MapKit

Question

现在我正在用 Swift 做一些不错的事情 3，我希望：计算 2 个地方之间的路线。我正在使用 Xcode 模拟器。我可以开车、步行或乘公交车计算。

这是我的：

mapview.delegate = self
let request = MKDirectionsRequest()
request.source = MKMapItem(placemark: MKPlacemark(coordinate: CLLocationCoordinate2D(latitude: 40.203314, longitude: -8.410257), addressDictionary: nil))
    request.destination = MKMapItem(placemark: MKPlacemark(coordinate: CLLocationCoordinate2D(latitude: 40.112808, longitude: -8.498689), addressDictionary: nil))
    request.requestsAlternateRoutes = false
    //request.transportType = .automobile
    request.transportType = .transit

    let directions = MKDirections(request: request)

    directions.calculate { [unowned self] response, error in
        guard let unwrappedResponse = response else { return }

        for route in unwrappedResponse.routes {
            self.mapview.add(route.polyline)
            self.mapview.setVisibleMapRect(route.polyline.boundingMapRect, animated: true)
            print("Distance: \(route.distance/1000) m")
            print("ETA: \(route.expectedTravelTime/60) min")


            for step in route.steps {
                print(step.instructions)
            }


        }

    }

我已经设置了密码，无论是驾车还是步行，一切都适用。但是，中转选项没有任何作用。

这是为什么？

Answer 1

运输类型 .transit 没有方向，很遗憾，只有 ETA

MapKit - MKDirectionsRequest() 的传输类型不工作

MapKit - transit type for MKDirectionsRequest() not Working

swift

mkdirection
