地图框导航：“Route”类型的值没有成员“member”

Question

类型为“Route”的值没有成员“coordinates”

在学习简单的youtube教程时遇到了这个错误。试着画一条路线。有人知道我为什么会收到这个错误吗？是pods的问题吗？

这些都是安装好的。谢谢!

    pod 'Mapbox-iOS-SDK', '~> 5.6'
      pod 'MapboxCoreNavigation', :git => 'https://github.com/mapbox/mapbox-navigation-ios.git', :tag => 'v1.0.0-alpha.1'
      pod 'MapboxNavigation', :git => 'https://github.com/mapbox/mapbox-navigation-ios.git', :tag => 'v1.0.0-alpha.1'

所以我设法找到了示例应用程序和错误。

以下是示例应用程序中的代码，它给出的错误为

‘

’类型的coordinates值没有成员'coordinates‘@routes?.first?.coordinates

Directions.shared.calculate(routeOptions) { (waypoints, routes, error) in
        guard let routeCoordinates = routes?.first?.coordinates, error == nil else {
            print(error!.localizedDescription)
            return
        }

        //
        // ❗️IMPORTANT❗️
        // Use `Directions.calculateRoutes(matching:completionHandler:)` for navigating on a map matching response.
        //
        let matchOptions = NavigationMatchOptions(coordinates: routeCoordinates)

        // By default, each waypoint separates two legs, so the user stops at each waypoint.
        // We want the user to navigate from the first coordinate to the last coordinate without any stops in between.
        // You can specify more intermediate waypoints here if you’d like.
        for waypoint in matchOptions.waypoints.dropFirst().dropLast() {
            waypoint.separatesLegs = false
        }

        Directions.shared.calculateRoutes(matching: matchOptions) { (waypoints, routes, error) in
            guard let route = routes?.first, error == nil else { return }

            // Set the route
            self.navigationViewController?.route = route
        }
    }

它必须按如下方式重写。

        Directions.shared.calculate(routeOptions) { (waypoints, routes, error) in
        guard let firstRoute = routes?.first, let waypoints = waypoints, error == nil else {
            print(error!.localizedDescription)
            return
        }

        //
        // ❗️IMPORTANT❗️
        // Use `Directions.calculateRoutes(matching:completionHandler:)` for navigating on a map matching response.
        //

        let matchOptions = NavigationMatchOptions(waypoints: waypoints)

        // By default, each waypoint separates two legs, so the user stops at each waypoint.
        // We want the user to navigate from the first coordinate to the last coordinate without any stops in between.
        // You can specify more intermediate waypoints here if you’d like.
        for waypoint in matchOptions.waypoints.dropFirst().dropLast() {
            waypoint.separatesLegs = false
        }

        Directions.shared.calculateRoutes(matching: matchOptions) { (waypoints, routes, error) in
            guard let route = routes?.first, error == nil else { return }

            // Set the route
            self.navigationViewController?.route = route
        }
    }

请检查这是否解决了您的问题

安装在pod下方

pod 'Mapbox-iOS-SDK', '~> 5.2'  
pod 'MapboxNavigation', '~> 0.38.0'

然后写下下面的代码，它对我很有效

if(CLLocationManager.locationServicesEnabled()){

self.CurrentLat = self.locationManager.location?.coordinate.latitude

self.CurrentLong = self.locationManager.location?.coordinate.longitude

let origin = Waypoint(coordinate: CLLocationCoordinate2D(latitude: 
self.CurrentLat, longitude: self.CurrentLong), name: "Start Location")

let destination = Waypoint(coordinate: CLLocationCoordinate2D(latitude: yourDestinationLat, 
longitude:  yourDestinationLong), name: yourDestinationName)
// Set options
let options = NavigationRouteOptions(waypoints: [origin, destination])

// Request a route using MapboxDirections.swift
Directions.shared.calculate(options) { (waypoints, routes, error) in

guard let route = routes?.first else {
SVProgressHUD.showError(withStatus: "Unable to create a route. Please try 
again.")
   return
}

let viewController = NavigationViewController(for: route)
viewController.delegate = self
viewController.modalPresentationStyle = .fullScreen
self.present(viewController, animated: true, completion: nil)
SVProgressHUD.dismiss()
}
