iOS驾车路线规划（带实时路况）demo

前述

• 工程是基于iOS 3D地图SDK实现的
• 高德官方网站申请key.
• 阅读驾车出行路线规划.
• 查阅参考手册.

使用方法

• 运行demo请先执行pod install --repo-update 安装依赖库，完成后打开.xcworkspace 文件
• 如有疑问请参阅自动部署.

核心类／接口

类	接口	说明
AMapSearchDelegate	- (void)onRouteSearchDone:(AMapRouteSearchBaseRequest *)request response:(AMapRouteSearchResponse *)response	路径规划查询完成回调
MAMapViewDelegate	- (MAOverlayRenderer *)mapView:(MAMapView *)mapView rendererForOverlay:(id)overlay	地图上覆盖物的渲染的回调，可以设置路径线路的宽度，颜色等
MAMapViewDelegate	- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id)annotation	地图上的起始点，终点，拐点的标注的回调，可以自定义图标展示等

核心难点

Objective-C

//在地图上显示当前选择的路径
- (void)presentCurrentRouteCourse{

    if (self.totalRouteNums <= 0) {
        return;
    }

    [self.naviRoute removeFromMapView];  //清空地图上已有的路线

    self.infoLabel.text = [NSString stringWithFormat:@"共%u条路线，当前显示第%u条",(unsigned)self.totalRouteNums,(unsigned)self.currentRouteIndex + 1];  //提示信息

    MANaviAnnotationType type = MANaviAnnotationTypeDrive; //驾车类型

    AMapGeoPoint *startPoint = [AMapGeoPoint locationWithLatitude:self.startAnnotation.coordinate.latitude longitude:self.startAnnotation.coordinate.longitude]; //起点

    AMapGeoPoint *endPoint = [AMapGeoPoint locationWithLatitude:self.destinationAnnotation.coordinate.latitude longitude:self.destinationAnnotation.coordinate.longitude];  //终点

    //根据已经规划的路径，起点，终点，规划类型，是否显示实时路况，生成显示方案
    self.naviRoute = [MANaviRoute naviRouteForPath:self.route.paths[self.currentRouteIndex] withNaviType:type showTraffic:self.showTrafficSwitch.on startPoint:startPoint endPoint:endPoint];

    [self.naviRoute addToMapView:self.mapView];  //显示到地图上

    UIEdgeInsets edgePaddingRect = UIEdgeInsetsMake(RoutePlanningPaddingEdge, RoutePlanningPaddingEdge, RoutePlanningPaddingEdge, RoutePlanningPaddingEdge); 

    //缩放地图使其适应polylines的展示
    [self.mapView setVisibleMapRect:[CommonUtility mapRectForOverlays:self.naviRoute.routePolylines]
                        edgePadding:edgePaddingRect
                           animated:YES];
}

Swift

//在地图上显示当前选择的路径
func presentCurrentRouteCourse() {
    if self.totalRouteNums <= 0 {
        return
    }
    self.naviRoute?.removeFromMapView() //清空地图上已有的路线

    self.infoLabel.text = "共\(UInt(self.totalRouteNums))条路线，当前显示第\(UInt(self.currentRouteIndex) + 1)条"  //提示信息

    let type = MANaviAnnotationType.drive //驾车类型

    let startPoint = AMapGeoPoint.location(withLatitude: CGFloat(self.startAnnotation.coordinate.latitude), longitude: CGFloat(self.startAnnotation.coordinate.longitude)) //起点

    let endPoint = AMapGeoPoint.location(withLatitude: CGFloat(self.destinationAnnotation.coordinate.latitude), longitude: CGFloat(self.destinationAnnotation.coordinate.longitude))  //终点

    //根据已经规划的路径，起点，终点，规划类型，是否显示实时路况，生成显示方案
    self.naviRoute = MANaviRoute(for: self.route.paths[self.currentRouteIndex], withNaviType: type, showTraffic: self.showTrafficSwitch.isOn, start: startPoint, end: endPoint)
    self.naviRoute?.add(to: self.mapView)

    //显示到地图上
    let edgePaddingRect = UIEdgeInsetsMake(RoutePlanningPaddingEdge, RoutePlanningPaddingEdge, RoutePlanningPaddingEdge, RoutePlanningPaddingEdge)
    //缩放地图使其适应polylines的展示
    self.mapView.setVisibleMapRect(CommonUtility.mapRect(forOverlays: self.naviRoute?.routePolylines), edgePadding: edgePaddingRect, animated: true)
}
