iOS-traffic-transfer

公交换乘:在地图页面上，固定起点和终点，规划出公交路线，通过详情，进行列表的详情展示.

前述

• 工程是基于iOS 3D地图SDK实现的
• 高德官方网站申请key.
• 阅读公交出行路线规划.
• 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.routeArray.count <= 0) {
        return;
    }

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

    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

    //根据已经规划的换乘方案，起点，终点，生成显示方案
    self.naviRoute = [MANaviRoute naviRouteForTransit:self.route.transits[self.currentRouteIndex] 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];
}


//根据transit的具体字段，显示信息
- (void)setUpViewsWithData {

    NSInteger hours = self.transit.duration / 3600;
    NSInteger minutes = (NSInteger)(self.transit.duration / 60) % 60;
    self.timeInfoLabel.text = [NSString stringWithFormat:@"%u小时%u分钟（%u公里）",(unsigned)hours,(unsigned)minutes,(unsigned)self.transit.distance / 1000];
    self.taxiCostInfoLabel.text = [NSString stringWithFormat:@"打车约%.0f元",self.route.taxiCost];

    self.routeDetailDataArray = @[].mutableCopy;
    [self.routeDetailDataArray addObject:@{RoutePathDetailStepInfoImageName : @"start",RoutePathDetailStepInfoText : @"开始出发"}]; // 图片的名字，具体步骤的文字信息

    for (AMapSegment *segment in self.transit.segments) {

        AMapBusLine *busline = [segment.buslines firstObject];  // 地铁或者公交线路
        AMapWalking *walking = segment.walking;  //搭乘地铁或者公交前的步行信息

        if (walking.distance) {
            NSString *walkInfo = [NSString stringWithFormat:@"步行%u米",(unsigned)walking.distance];
            [self.routeDetailDataArray addObject:@{RoutePathDetailStepInfoImageName : @"walkRoute",RoutePathDetailStepInfoText : walkInfo}];
        }

        if (busline.name) {
            NSString *busImageName = @"busRoute";
            if ([busline.type isEqualToString:@"地铁线路"]) { //区分公交和地铁
                busImageName = @"underGround";
            }

            //viaBusStops途径的公交车站的数组，如需具体站名，可解析。
            NSString *busInfoText = [NSString stringWithFormat:@"乘坐%@，在 %@ 上车，途经 %u 站，在 %@ 下车",busline.name,busline.departureStop.name,(unsigned)(busline.viaBusStops.count + 1),busline.arrivalStop.name];
            [self.routeDetailDataArray addObject:@{RoutePathDetailStepInfoImageName : busImageName,RoutePathDetailStepInfoText : busInfoText}];

        } else if (railway.uid) {
            [self.routeDetailDataArray addObject:@{RoutePathDetailStepInfoImageName : @"railwayRoute",RoutePathDetailStepInfoText : railway.name}];
        }
    }

    [self.routeDetailDataArray addObject:@{RoutePathDetailStepInfoImageName : @"end",RoutePathDetailStepInfoText : @"抵达终点"}];

}
