首先按照百度地圖引入SDK 官網上都有教程 這里就不多說了
引入相關的頭文件 看百度demo里面 下面的是百度demo里面的文件 可以去那里拉
（這里自己簡單整理一下 方便自己查看）
<pre>
import <MapKit/MapKit.h>
import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相關所有的頭文件
import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地圖功能所有的頭文件
import <BaiduMapAPI_Search/BMKSearchComponent.h>//引入檢索功能所有的頭文件
import <BaiduMapAPI_Cloud/BMKCloudSearchComponent.h>//引入云檢索功能所有的頭文件
import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的頭文件
import <BaiduMapAPI_Utils/BMKUtilsComponent.h>//引入計算工具所有的頭文件
import <BaiduMapAPI_Radar/BMKRadarComponent.h>//引入周邊雷達功能所有的頭文件
//只引入所需的單個頭文件
import "RouteAnnotation.h"
import "UIImage+Rotate.h"
</pre>
聲明變量和協(xié)議
<pre>
@interface StorePathViewController ()<BMKMapViewDelegate,BMKRouteSearchDelegate,BMKLocationServiceDelegate,BMKGeoCodeSearchDelegate>
/** 地圖視圖 /
//@property (nonatomic, strong) BMKMapView mapView;
@property (weak, nonatomic) IBOutlet BMKMapView mapView;
/* 搜索 /
@property (nonatomic, strong) BMKRouteSearch routesearch;//路線查找
@property (nonatomic, strong) BMKLocationService *locService;//定位
@end
</pre>
按照百度地圖文檔進行設置代理個釋放
<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;// 此處記得不用的時候需要置nil，否則影響內存的釋放
self.routesearch.delegate = nil;
self.locService.delegate = nil;
}
</pre>
懶加載
<pre>
//搜索路線
(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>
定位開始
<pre>
-
(void)viewDidLoad {
[super viewDidLoad];
[self.view addSubview:self.mapView];
[_mapView setZoomEnabled:YES];
[_mapView setZoomLevel:13];//級別，3-19
_mapView.showMapScaleBar = YES;//比例尺
_mapView.showsUserLocation=YES;//顯示當前設備的位置
_mapView.showMapScaleBar = YES;_mapView.userTrackingMode = BMKUserTrackingModeFollow;//定位跟隨模式
[self.locService startUserLocationService];
[self storeLocationStars];
}
</pre>
獲取當前位置
<pre>
-(void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation {
[_mapView updateLocationData:userLocation];
CLLocationCoordinate2D coordinate = userLocation.location.coordinate;
startlocation = coordinate;
}
</pre>
對目的地進行標注
<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>
開始位置和目的地位置加入檢索信息
pragma mark - 開始和終點位置
<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>
公交路線開始檢索
<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檢索發(fā)送成功");
}
else
{
NSLog(@"bus檢索發(fā)送失敗");
}
}
</pre>
駕車路線開始檢索
<pre>
pragma mark 駕車搜索
-(IBAction)onClickDriveSearch
{
//[self.mapView removeFromSuperview];
/// 駕車查詢基礎信息類
BMKDrivingRoutePlanOption *drivingRouteSearchOption = [[BMKDrivingRoutePlanOption alloc]init];
drivingRouteSearchOption.from = [self startPt];
drivingRouteSearchOption.to = [self endPt];
BOOL flag = [_routesearch drivingSearch:drivingRouteSearchOption];
if(flag)
{
NSLog(@"car檢索發(fā)送成功");
}
else
{
NSLog(@"car檢索發(fā)送失敗");
}
[SVProgressHUD showWithStatus:SearchPathMsg];
}
</pre>
步行路線開始檢索
<pre>
pragma mark 步行搜索
-(IBAction)onClickWalkSearch
{
/// 步行查詢基礎信息類
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檢索發(fā)送成功");
}
else
{
NSLog(@"walk檢索發(fā)送失敗");
}
}</pre>
三種路線的計算 （直接拷貝過來的）
