总结一下百度地图 定位 大头针 和划线和城市检索的功能

- (void)viewDidLoad {
    [super viewDidLoad];
   
   
    //初始化BMKLocationService
    _locService = [[BMKLocationService alloc]init];
    _locService.delegate = self;
    //启动LocationService

    [_locService startUserLocationService];

}

 

在delegate中更新位置和对应方向

#pragma mark--BMKLocationServiceDelegate 定位当前位置
- (void)didUpdateUserHeading:(BMKUserLocation *)userLocation
{
    NSLog(@"heading is %@",userLocation.heading);
}
//处理位置坐标更新
- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation
{
    NSLog(@"didUpdateUserLocation lat %f,long %f",userLocation.location.coordinate.latitude,userLocation.location.coordinate.longitude);
    _handleView.mapView.showsUserLocation = YES;//显示定位图层
    [_handleView.mapView updateLocationData:userLocation];
   
    CGFloat longitude = userLocation.location.coordinate.longitude;
    CGFloat latitude = userLocation.location.coordinate.latitude;
   
    BMKPointAnnotation* item = [[BMKPointAnnotation alloc]init];
    item.coordinate = CLLocationCoordinate2DMake(latitude, longitude);
   
    [self.handleView.mapView removeAnnotations:self.handleView.mapView.annotations];
   
    [PublicTools doItInAsynMainThread:^{
       
        [self.handleView.mapView addAnnotation:item];
       
        [self.handleView.mapView setCenterCoordinate:CLLocationCoordinate2DMake(latitude, longitude) animated:YES];
        [_locService stopUserLocationService];
    }];

   

}

 

添加大头针

- (void)bmk {
   
    CGFloat longitude = [self.handleView.model.longitude floatValue];
    CGFloat latitude = [self.handleView.model.latitude floatValue];
   
    BMKPointAnnotation* item = [[BMKPointAnnotation alloc]init];
    item.coordinate = CLLocationCoordinate2DMake(latitude, longitude);
   
    [self.handleView.mapView removeAnnotations:self.handleView.mapView.annotations];
   
    [PublicTools doItInAsynMainThread:^{
       
        [self.handleView.mapView addAnnotation:item];
       

        [self.handleView.mapView setCenterCoordinate:CLLocationCoordinate2DMake(latitude, longitude) animated:YES];

 

自定义大头针

/ 根据anntation生成对应的View
- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation
{
    NSString *AnnotationViewID = [NSString stringWithFormat:@"renameMark%d",i];
   
    newAnnotation = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];
    // 设置颜色
    ((BMKPinAnnotationView*)newAnnotation).pinColor = BMKPinAnnotationColorPurple;
    // 从天上掉下效果
    ((BMKPinAnnotationView*)newAnnotation).animatesDrop = YES;
    // 设置可拖拽
    ((BMKPinAnnotationView*)newAnnotation).draggable = YES;
    //设置大头针图标
    ((BMKPinAnnotationView*)newAnnotation).image = [UIImage imageNamed:@"zhaohuoche"];
   
    UIView *popView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 60)];
    //设置弹出气泡图片
    UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"wenzi"]];
    image.frame = CGRectMake(0, 0, 100, 60);
    [popView addSubview:image];
    //自定义显示的内容
    UILabel *driverName = [[UILabel alloc]initWithFrame:CGRectMake(0, 3, 100, 20)];
    driverName.text = @"张XX师傅";
    driverName.backgroundColor = [UIColor clearColor];
    driverName.font = [UIFont systemFontOfSize:14];
    driverName.textColor = [UIColor whiteColor];
    driverName.textAlignment = NSTextAlignmentCenter;
    [popView addSubview:driverName];
   
    UILabel *carName = [[UILabel alloc]initWithFrame:CGRectMake(0, 25, 100, 20)];
    carName.text = @"京A123456";
    carName.backgroundColor = [UIColor clearColor];
    carName.font = [UIFont systemFontOfSize:14];
    carName.textColor = [UIColor whiteColor];
    carName.textAlignment = NSTextAlignmentCenter;
    [popView addSubview:carName];
    BMKActionPaopaoView *pView = [[BMKActionPaopaoView alloc]initWithCustomView:popView];
    pView.frame = CGRectMake(0, 0, 100, 60);
    ((BMKPinAnnotationView*)newAnnotation).paopaoView = nil;
    ((BMKPinAnnotationView*)newAnnotation).paopaoView = pView;
    i++;
    return newAnnotation;
   

}

 

百度地图画线

//描点画线
    if (self.lastCoor.latitude) {
    CLLocationCoordinate2D coors[2] = {0};
    coors[0].latitude = self.lastCoor.latitude;
    coors[0].longitude = self.lastCoor.longitude;
    coors[1].latitude = touchMapCoordinate.latitude;
    coors[1].longitude = touchMapCoordinate.longitude;
    BMKPolyline *polyline = [BMKPolyline polylineWithCoordinates:coors count:2];
    [self.handleView.mapView addOverlay:polyline];
   
    }

    self.lastCoor = touchMapCoordinate;

    }];

 

在delegate中画线

// 在地图上画线

- (BMKOverlayView *)mapView:(BMKMapView *)mapView viewForOverlay:(id <BMKOverlay>)overlay

   if ([overlay isKindOfClass:[BMKPolyline class]]) {
        BMKPolylineView *overlayView = [[BMKPolylineView alloc] initWithOverlay:overlay];
        overlayView.strokeColor = [[UIColor redColor] colorWithAlphaComponent:1];
        overlayView.lineWidth = 3.0;
        return overlayView;
    }

 

    return nil;

}
