篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了总结一下百度地图定位大头针和划线和城市检索的功能相关的知识，希望对你有一定的参考价值。

- (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;

}
