百度地图3.1.0路线规划

首先按照百度地图引入SDK 官网上都有教程 这里就不多说了

引入相关的头文件 看百度demo里面 下面的是百度demo里面的文件 可以去那里拉
(这里自己简单整理一下 方便自己查看)
<pre>

import <MapKit/MapKit.h>

import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相关所有的头文件

import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地图功能所有的头文件

import <BaiduMapAPI_Search/BMKSearchComponent.h>//引入检索功能所有的头文件

import <BaiduMapAPI_Cloud/BMKCloudSearchComponent.h>//引入云检索功能所有的头文件

import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的头文件

import <BaiduMapAPI_Utils/BMKUtilsComponent.h>//引入计算工具所有的头文件

import <BaiduMapAPI_Radar/BMKRadarComponent.h>//引入周边雷达功能所有的头文件

//只引入所需的单个头文件

import "RouteAnnotation.h"

import "UIImage+Rotate.h"

</pre>

声明变量和协议

<pre>
@interface StorePathViewController ()<BMKMapViewDelegate,BMKRouteSearchDelegate,BMKLocationServiceDelegate,BMKGeoCodeSearchDelegate>

/** 地图视图 /
//@property (nonatomic, strong) BMKMapView
mapView;
@property (weak, nonatomic) IBOutlet BMKMapView mapView;
/
* 搜索 /
@property (nonatomic, strong) BMKRouteSearch
routesearch;//路线查找
@property (nonatomic, strong) BMKLocationService *locService;//定位

@end
</pre>

按照百度地图文档进行设置代理个释放

<pre>

  • (void)viewWillAppear:(BOOL)animated
    {
    // [super viewWillAppear:animated];
    [self.mapView viewWillAppear];
    self.mapView.delegate = self;
    self.routesearch.delegate = self;
    self.locService.delegate =self;
    }
  • (void)viewWillDisappear:(BOOL)animated
    {
    [self.mapView viewWillDisappear];
    self.mapView.delegate = nil;// 此处记得不用的时候需要置nil,否则影响内存的释放
    self.routesearch.delegate = nil;
    self.locService.delegate = nil;
    }
    </pre>

懒加载

<pre>
//搜索路线

  • (BMKRouteSearch *)routesearch{
    if (_routesearch == nil) {
    _routesearch = [[BMKRouteSearch alloc] init];
    }
    return _routesearch;
    }
    //定位

  • (BMKLocationService*)locService {
    if (_locService == nil) {
    _locService = [[BMKLocationService alloc] init];

    }
    return _locService;

}
</pre>

定位开始

<pre>

  • (void)viewDidLoad {
    [super viewDidLoad];
    [self.view addSubview:self.mapView];
    [_mapView setZoomEnabled:YES];
    [_mapView setZoomLevel:13];//级别,3-19
    _mapView.showMapScaleBar = YES;//比例尺
    _mapView.showsUserLocation=YES;//显示当前设备的位置
    _mapView.showMapScaleBar = YES;

    _mapView.userTrackingMode = BMKUserTrackingModeFollow;//定位跟随模式

    [self.locService startUserLocationService];
    [self storeLocationStars];
    }
    </pre>

获取当前位置

<pre>
-(void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation {
[_mapView updateLocationData:userLocation];

CLLocationCoordinate2D coordinate = userLocation.location.coordinate;
startlocation = coordinate;

}
</pre>

对目的地进行标注

<pre>

  • (void)storeLocationStars {
    if (_mainListModel.latitude && _mainListModel.longitude) {
    BMKPointAnnotation *point1 = [[BMKPointAnnotation alloc]init];

      point1.coordinate = CLLocationCoordinate2DMake([_mainListModel.latitude doubleValue], [_mainListModel.longitude doubleValue]);
      endLocation = point1.coordinate;
      point1.title = _mainListModel.name;
      
      [_mapView addAnnotation:point1];
    

    }

}
</pre>

开始位置和目的地位置加入检索信息

pragma mark - 开始和终点位置

<pre>

  • (BMKPlanNode *)startPt {

    BMKPlanNode* start = [[BMKPlanNode alloc]init];
    start.pt = startlocation;
    return start;

}

  • (BMKPlanNode )endPt {
    BMKPlanNode
    end = [[BMKPlanNode alloc]init];
    end.pt = endLocation;
    return end;
    }
    </pre>

公交路线开始检索

<pre>
-(IBAction)onClickBusSearch
{

 BMKMassTransitRoutePlanOption *MassTransitRouteSearchOption = [[BMKMassTransitRoutePlanOption alloc]init];
MassTransitRouteSearchOption.from = [self startPt];
MassTransitRouteSearchOption.to = [self endPt];
BOOL flag = [_routesearch massTransitSearch:MassTransitRouteSearchOption];
[SVProgressHUD showWithStatus:SearchPathMsg];

if(flag)
{
    NSLog(@"bus检索发送成功");
}
else
{
    NSLog(@"bus检索发送失败");
}

}
</pre>

驾车路线开始检索

<pre>

pragma mark 驾车搜索

-(IBAction)onClickDriveSearch
{
//[self.mapView removeFromSuperview];

/// 驾车查询基础信息类
BMKDrivingRoutePlanOption *drivingRouteSearchOption = [[BMKDrivingRoutePlanOption alloc]init];
drivingRouteSearchOption.from = [self startPt];
drivingRouteSearchOption.to = [self endPt];
BOOL flag = [_routesearch drivingSearch:drivingRouteSearchOption];
if(flag)
{
    NSLog(@"car检索发送成功");
}
else
{
    NSLog(@"car检索发送失败");
}

[SVProgressHUD showWithStatus:SearchPathMsg];

}
</pre>

步行路线开始检索

<pre>

pragma mark 步行搜索

-(IBAction)onClickWalkSearch
{

/// 步行查询基础信息类
BMKWalkingRoutePlanOption *walkingRouteSearchOption = [[BMKWalkingRoutePlanOption alloc]init];
walkingRouteSearchOption.from = [self startPt];
walkingRouteSearchOption.to = [self endPt];
BOOL flag = [_routesearch walkingSearch:walkingRouteSearchOption];
[SVProgressHUD showWithStatus:SearchPathMsg];

if(flag)
{
    NSLog(@"walk检索发送成功");
}
else
{
    NSLog(@"walk检索发送失败");
}

}</pre>
