ios 百度地图（开启百度地图之旅 3 划线 导航 大头针常用方法）

上篇开启百度之旅 2

一 补充大头针和气泡常用的方法

1.1 初始化大头针给大头针标题

pointAnnotation = [[BMKPointAnnotation alloc] init];;

pointAnnotation.title = @“今天天气不错“;

1.2 点击大头针方法

- (void)mapView:(BMKMapView *)mapView didSelectAnnotationView:(BMKAnnotationView *)view {
    
      NSLog(@"点击大头针");
}

1.3 点击气泡方法

- (void)mapView:(BMKMapView *)mapView annotationViewForBubble:(BMKPointAnnotation *)view{
    NSLog(@"点击气泡");
}

二 定位到当前位置 地图画线（公交划线为例）

2.1代理

2.2 导入头文件

#import //只引入所需的单个头文件

#######import
#######import
#######import //引入定位功能所有的头文件
#######import "UIImage+Rotate.h"(在百度地图Demo中找到拖到自己的工程中)
#######import "RouteAnnotation.h"(在百度地图Demo中找到拖到自己的工程中)

2.3 设置

//需要注意把.m文件改成.mm文件
#define MYBUNDLE_NAME @ "mapapi.bundle"
#define MYBUNDLE_PATH [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: MYBUNDLE_NAME]
#define MYBUNDLE [NSBundle bundleWithPath: MYBUNDLE_PATH]
#define BMKSPAN 0.02

2.4

{
     int _type; ///<0:起点 1：终点 2：公交 3：地铁 4:驾乘 5:途经点
     int _degree;
     BMKRouteSearch* _routesearch;
     BMKLocationService* _locService;
}
@property (nonatomic) int type;
@property (nonatomic) int degree;
@property (strong, nonatomic) IBOutlet BMKMapView *mapView;
@property (nonatomic,assign) CLLocationCoordinate2D coor;

2.4

  //适配ios7
    if( ([[[UIDevice currentDevice] systemVersion] doubleValue]>=7.0))
    {
        self.navigationController.navigationBar.translucent = NO;
    }
    _mapView = [[BMKMapView alloc]initWithFrame:CGRectMake(0, 0, WIDTH,HEIGHT)];
    _mapView.delegate = self;
   //初始化BMKRouteSearch
    _routesearch = [[BMKRouteSearch alloc] init];
   
    //初始化BMKLocationService(定位)
    _locService = [[BMKLocationService alloc]init];
    _locService.delegate = self;
    //启动LocationService
    [_locService startUserLocationService];
    _mapView.showsUserLocation = YES;//显示定位图层
    _mapView.showsUserLocation = NO;
    _mapView.userTrackingMode = BMKUserTrackingModeNone;
    _mapView.showsUserLocation = YES;
    [self.view addSubview:_mapView];
 

2.5

-(void)viewWillAppear:(BOOL)animated {
    [_mapView viewWillAppear];
    _mapView.delegate = self; // 此处记得不用的时候需要置nil，否则影响内存的释放
    _routesearch.delegate = self; // 此处记得不用的时候需要置nil，否则影响内存的释放
}

-(void)viewWillDisappear:(BOOL)animated {
    [_mapView viewWillDisappear];
    _mapView.delegate = nil; // 不用时，置nil
    _routesearch.delegate = nil; // 不用时，置nil
}

- (void)dealloc {
    if (_routesearch != nil) {
        _routesearch = nil;
    }
    if (_mapView) {
        _mapView = nil;
    }
}

2.6以下是划线必备

#pragma mark - BMKMapViewDelegate

- (BMKAnnotationView *)mapView:(BMKMapView *)view viewForAnnotation:(id )annotation
{
    if ([annotation isKindOfClass:[RouteAnnotation class]]) {
        return [self getRouteAnnotationView:view viewForAnnotation:(RouteAnnotation*)annotation];
    }
    return nil;
}
//设置线的颜色
- (BMKOverlayView*)mapView:(BMKMapView *)map viewForOverlay:(id)overlay
{
    if ([overlay isKindOfClass:[BMKPolyline class]]) {
        BMKPolylineView* polylineView = [[BMKPolylineView alloc] initWithOverlay:overlay];
        polylineView.fillColor = [[UIColor alloc] initWithRed:0 green:1 blue:1 alpha:1];
        polylineView.strokeColor = [[UIColor alloc] initWithRed:0 green:0 blue:1 alpha:0.7];
        polylineView.lineWidth = 5.0;
        return polylineView;
    }
    return nil;
}

#pragma mark - BMKRouteSearchDelegate
/**
 *返回公交搜索结果（点击进去有其他的结果其他的方法）
 */
- (void)onGetTransitRouteResult:(BMKRouteSearch*)searcher result:(BMKTransitRouteResult*)result errorCode:(BMKSearchErrorCode)error
{
    NSArray* array = [NSArray arrayWithArray:_mapView.annotations];
    [_mapView removeAnnotations:array];
    array = [NSArray arrayWithArray:_mapView.overlays];
    [_mapView removeOverlays:array];
    if (error == BMK_SEARCH_NO_ERROR) {
        BMKTransitRouteLine* plan = (BMKTransitRouteLine*)[result.routes objectAtIndex:0];
        // 计算路线方案中的路段数目
        NSInteger size = [plan.steps count];
        int planPointCounts = 0;
        for (int i = 0; i < size; i++) {
            BMKTransitStep* 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];
                item.coordinate = plan.terminal.location;
                item.title = @"终点";
                item.type = 1;
                [_mapView addAnnotation:item]; // 添加起点标注
            }
            RouteAnnotation* item = [[RouteAnnotation alloc]init];
            item.coordinate = transitStep.entrace.location;
            item.title = transitStep.instruction;
            item.type = 3;
            [_mapView addAnnotation:item];
            
            //轨迹点总数累计
            planPointCounts += transitStep.pointsCount;
        }
        
        //轨迹点
        BMKMapPoint * temppoints =  new BMKMapPoint[planPointCounts];
        int i = 0;
        for (int j = 0; j < size; j++) {
            BMKTransitStep* transitStep = [plan.steps objectAtIndex:j];
            int k=0;
            for(k=0;k rbX) {
            rbX = pt.x;
        }
        if (pt.y > ltY) {
            ltY = pt.y;
        }
        if (pt.y < rbY) {
            rbY = pt.y;
        }
    }
    _mapView.zoomLevel = _mapView.zoomLevel - 0.3;
}

2.7 开始画线

//定位


/**
 *用户位置更新后，会调用此函数
 *@param userLocation 新的用户位置
 */
- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation
{   [_locService stopUserLocationService];
    NSLog(@"didUpdateUserLocation lat %f,long %f",userLocation.location.coordinate.latitude,userLocation.location.coordinate.longitude);
    
    CLLocation *location=[[CLLocation alloc]initWithLatitude:userLocation.location.coordinate.latitude longitude:userLocation.location.coordinate.longitude];
    //获得一个合适的区域
    CLLocationCoordinate2D center = CLLocationCoordinate2DMake(location.coordinate.latitude,location.coordinate.longitude);
    BMKCoordinateSpan span;
    
    span.latitudeDelta=BMKSPAN;
    
    span.longitudeDelta=BMKSPAN;
    
    BMKCoordinateRegion fitsRegion;
    
    fitsRegion.center=center;////限制地图显示范围
    
    fitsRegion.span=span;////限制地图显示范围
    #pragma mark -划线
    [self.mapView setRegion:fitsRegion animated:YES];
    BMKPlanNode* start = [[BMKPlanNode alloc]init];
    CLLocationCoordinate2D coor1;
    coor1.latitude = userLocation.location.coordinate.latitude;
    coor1.longitude = userLocation.location.coordinate.longitude;;
    start.pt = coor1;
    start.name = @"起点";
    start.cityName = @"郑州";
    _coor = coor1;
    
    BMKPlanNode* end = [[BMKPlanNode alloc]init];
    CLLocationCoordinate2D coor2;
    coor2.latitude = 34.721647;
    coor2.longitude = 113.710344;
    end.pt = coor2;
    end.cityName = @"郑州";
    end.name =@"终点";
    BMKTransitRoutePlanOption *transitRouteSearchOption = [[BMKTransitRoutePlanOption alloc]init];
    transitRouteSearchOption.city= @"郑州";
    transitRouteSearchOption.from = start;
    transitRouteSearchOption.to = end;
    BOOL flag = [_routesearch transitSearch:transitRouteSearchOption];
    
    if(flag)
    {
        NSLog(@"bus检索发送成功");
    }
    else
    {
        NSLog(@"bus检索发送失败");
    }
    
    [_mapView updateLocationData:userLocation];
}

三 导航（调用百度客户端，没有客户端调取网页版）

3.1导航配置

//plish文件添加
 LSApplicationQueriesSchemes
    
        baidumap
    

3.2导入头文件

#######import

3.3

   BMKOpenTransitRouteOption *opt = [[BMKOpenTransitRouteOption alloc] init];
    //    opt.appName = @"SDK调起Demo";
    opt.appScheme = @"baidumapsdk://mapsdk.baidu.com";
    //初始化起点节点
    BMKPlanNode* start = [[BMKPlanNode alloc]init];
    //指定起点经纬度
    CLLocationCoordinate2D coor1;
    coor1.latitude = _coor.latitude;
    coor1.longitude = _coor.longitude;
    //指定起点名称
    start.name = @"当前位置";
    start.pt = coor1;
    //指定起点
    opt.startPoint = start;
    
    //初始化终点节点
    BMKPlanNode* end = [[BMKPlanNode alloc]init];
    CLLocationCoordinate2D coor2;
    coor2.latitude = 34.721647;
    coor2.longitude = 113.710344;
    end.pt = coor2;
    //指定终点名称
    end.name =@"终点";
    opt.endPoint = end;
    
    BMKOpenErrorCode code = [BMKOpenRoute openBaiduMapTransitRoute:opt];
    NSLog(@"%d", code);
