一、细说百度地图的路径规划

路径规划主要有这么几种

1.公交路径规划

1.1 市内公交规划(暂时不在这里说)

1.2 跨市/省公交规划

// 导入头文件

#import

#pragma mark: - 公交路线

- (void)showBusSearch {

//线路检索节点信息

BMKPlanNode *start = [[BMKPlanNode alloc] init];

start.pt = self.userLocation.location.coordinate;

start.cityName = @"南宁";

BMKPlanNode *end = [[BMKPlanNode alloc] init];

// 108.296699,22.842406

CLLocationCoordinate2D endCoordinate = CLLocationCoordinate2DMake(22.842406, 108.296699);

end.pt = endCoordinate;

end.cityName = @"南宁";

BMKMassTransitRoutePlanOption *drivingRouteSearchOption = [[BMKMassTransitRoutePlanOption alloc] init];

drivingRouteSearchOption.from = start;

drivingRouteSearchOption.to = end;

BOOL flag = [_routesearch massTransitSearch:drivingRouteSearchOption];

if (flag) {

NSLog(@"%s - 设置成功！",__func__);

}else {

debugLog(@"设置失败");

}

/**

*返回公共交通路线检索结果(new)回调方法

*@param searcher 搜索对象

*@param result 搜索结果，类型为BMKMassTransitRouteResult

*@param error 错误号，@see BMKSearchErrorCode

- (void)onGetMassTransitRouteResult:(BMKRouteSearch*)searcher result:(BMKMassTransitRouteResult*)result errorCode:(BMKSearchErrorCode)error {

debugLog(@"公交方案-%@",result.routes);

if (error == BMK_SEARCH_NO_ERROR) {

for (int i = 0; i < result.routes.count; i++ ) {

BMKMassTransitRouteLine *massTransitRouteLine = result.routes[i];

// 保存换乘说明

NSMutableArray *instructions = [NSMutableArray array];

// 换乘的交通工具

NSMutableArray *stepTypes = [NSMutableArray array];

// 价格信息

debugLog(@"价格-%f",massTransitRouteLine.price);

debugLog(@"时间分钟-%d",massTransitRouteLine.duration.minutes);

debugLog(@"起点-%@",massTransitRouteLine.starting.title);

debugLog(@"终点-%@",massTransitRouteLine.terminal.title);

debugLog(@"路段方案%@",massTransitRouteLine.steps);

// 所有路段的信息

for ( int j = 0; j < massTransitRouteLine.steps.count; j++) {

BMKMassTransitStep *step = massTransitRouteLine.steps[j];

debugLog(@"%@",step.steps);

for ( int k = 0; k< step.steps.count; k++) {

BMKMassTransitSubStep *subStep = step.steps[k];

debugLog(@"换乘说明-%@",subStep.instructions);

[instructions addObject:subStep.instructions];

debugLog(@"路段类型-%u",subStep.stepType);

if(subStep.stepType != 5) { // 5为步行

if (subStep.vehicleInfo.name) {

[stepTypes addObject:subStep.vehicleInfo.name];

}

// 当路段为公交路段或地铁路段时，可以获取交通工具信息

debugLog(@"交通工具信息-%@",subStep.vehicleInfo.name);

}

2.驾车路径规划

#pragma mark 驾车路线

-(void)showDriveSearch {

//线路检索节点信息

BMKPlanNode *start = [[BMKPlanNode alloc] init];

start.pt = self.userLocation.location.coordinate;

start.cityName = @"南宁";

BMKPlanNode *end = [[BMKPlanNode alloc] init];

CLLocationCoordinate2D endCoordinate = CLLocationCoordinate2DMake(22.842406, 108.296699);

end.pt = endCoordinate;

end.cityName = @"南宁";

BMKDrivingRoutePlanOption *drivingRouteSearchOption = [[BMKDrivingRoutePlanOption alloc] init];

drivingRouteSearchOption.from = start;

drivingRouteSearchOption.to = end;

BOOL flag = [_routesearch drivingSearch:drivingRouteSearchOption];

if (flag) {

NSLog(@"%s - 设置成功！",__func__);

}else {

debugLog(@"设置失败");

}

#pragma mark 返回驾乘搜索结果

- (void)onGetDrivingRouteResult:(BMKRouteSearch*)searcher result:(BMKDrivingRouteResult*)result errorCode:(BMKSearchErrorCode)error {

if (error == BMK_SEARCH_NO_ERROR) {

for (int i = 0; i < result.routes.count; i++) {

NSMutableArray *instruction = [NSMutableArray array];

NSMutableArray *waypoints = [NSMutableArray array];

//表示一条驾车路线

BMKDrivingRouteLine *plan = result.routes[i];

for (int k = 0; k < plan.wayPoints.count; k++) {

BMKPlanNode *node = plan.wayPoints[k];

[waypoints addObject:node.name];

}

for (int j = 0; j < plan.steps.count; j++) {

//表示驾车路线中的一个路段

BMKDrivingStep* transitStep = [plan.steps objectAtIndex:j];

[instruction addObject:transitStep.instruction];

}

3.步行路径规划

#pragma mark: - 步行

- (void)showWalkSearch {

//线路检索节点信息

BMKPlanNode *start = [[BMKPlanNode alloc] init];

start.pt = self.userLocation.location.coordinate;

start.cityName = @"南宁";

BMKPlanNode *end = [[BMKPlanNode alloc] init];

CLLocationCoordinate2D endCoordinate = CLLocationCoordinate2DMake(22.842406, 108.296699);

end.pt = endCoordinate;

end.cityName = @"南宁";

BMKWalkingRoutePlanOption *drivingRouteSearchOption = [[BMKWalkingRoutePlanOption alloc] init];

drivingRouteSearchOption.from = start;

drivingRouteSearchOption.to = end;

BOOL flag = [_routesearch walkingSearch:drivingRouteSearchOption];

if (flag) {

NSLog(@"%s - 设置成功！",__func__);

}else {

debugLog(@"设置失败");

}

/**

*返回步行搜索结果

*@param searcher 搜索对象

*@param result 搜索结果，类型为BMKWalkingRouteResult

*@param error 错误号，@see BMKSearchErrorCode

- (void)onGetWalkingRouteResult:(BMKRouteSearch*)searcher result:(BMKWalkingRouteResult*)result errorCode:(BMKSearchErrorCode)error {

debugLog(@"步行方案--%@",result.routes);

if (error == BMK_SEARCH_NO_ERROR) {

for (int i = 0; i < result.routes.count; i++) {

NSMutableArray *instructions = [NSMutableArray array];

BMKWalkingRouteLine *walkingRouteLine = result.routes[i];

//debugLog(@"途径 ---%@", walkingRouteLine.wayPointPoiList);

debugLog(@"路线长度 -- %d", walkingRouteLine.distance);

debugLog(@"需要花费的时间 %d",walkingRouteLine.duration.minutes);

for (int j = 0; j < walkingRouteLine.steps.count; j++) {

BMKWalkingStep *step = walkingRouteLine.steps[j];

debugLog(@"入口信息 -- %@",step.entraceInstruction);

debugLog(@"出口信息 -- %@",step.exitInstruction);

debugLog(@"指示信息 -- %@",step.instruction);

[instructions addObject:step.instruction];

}

4.骑车路径规划(暂时不总结)

5.根据路径规划划线

- (void)showCarRoutePlan {

// 计算路线方案中的路段数目

int size = (int)[self.drivingRouteLine.steps count];

BMKDrivingRouteLine *plan = self.drivingRouteLine;

int planPointCounts = 0;

for (int i = 0; i < size; i++) {

//表示驾车路线中的一个路段

BMKDrivingStep* transitStep = [plan.steps objectAtIndex:i];

if(i==0){

RouteAnnotation* item = [[RouteAnnotation alloc]init];

item.coordinate = plan.starting.location;

item.title = @"起点";

item.type = 0;

[_mapView addAnnotation:item]; // 添加起点标注

}else if(i==size-1){

RouteAnnotation* item = [[RouteAnnotation alloc]init];

二、使用本机的地图导航

通常自己的手机都会安装有百度地图、高德地图、腾讯等等

1.实现步骤

1.1 添加应用白名单

baidumap

iosamap

comgooglemaps

qqmap

1.2 info.plist添加对应的url schemes

百度地图： baidumap://

腾讯地图： qqmap://

谷歌地图： comgooglemaps://

高德地图： iosamap://

1.3 使用的第三方框架

pod 'LCActionSheet' // 弹窗选择

pod 'JZLocationConverter' // 经纬度转换(主要解决百度地图和谷歌地图用的不是同一种标准的问题)

1.4 具体实现代码

// 引入头文件

#import

#pragma mark - 导航方法

- (NSArray *)getInstalledMapApp

{

NSArray *locationArray = [self.poiMD.address_x_y componentsSeparatedByString:@","];

// lat lng

CLLocationCoordinate2D endLocation = CLLocationCoordinate2DMake([locationArray.lastObject floatValue], [locationArray.firstObject floatValue]);

NSMutableArray *maps = [NSMutableArray array];

//苹果地图

NSMutableDictionary *iosMapDic = [NSMutableDictionary dictionary];

iosMapDic[@"title"] = @"苹果地图";

[maps addObject:iosMapDic];

//百度地图

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {

NSMutableDictionary *baiduMapDic = [NSMutableDictionary dictionary];

baiduMapDic[@"url"] = urlString;

}

//高德地图

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {

}

//腾讯地图

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]) {

qqMapDic[@"title"] = @"腾讯地图";

NSString *urlString = [[NSString stringWithFormat:@"qqmap://map/routeplan?from=我的位置&type=drive&tocoord=%f,%f&to=终点&coord_type=1&policy=0",endLocation.latitude, endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

qqMapDic[@"url"] = urlString;

[maps addObject:qqMapDic];

}

return maps;

}

- (void)showLCActionSheet {

NSArray *maps = [self getInstalledMapApp];

NSMutableArray *mapsA = [NSMutableArray array];

for (NSDictionary *dict in maps) {

[mapsA addObject:dict[@"title"]];

}

LCActionSheet *actionSheet = [LCActionSheet sheetWithTitle:@"请选择" cancelButtonTitle:@"取消" clicked:^(LCActionSheet * _Nonnull actionSheet, NSUInteger buttonIndex) {

if (buttonIndex == 0) { // 当前选择了取消

return ;

}

return;

}
