iOS百度地图---地图覆盖物

 

1、添加标注

 

...

   CLLocationCoordinate2D coor;

    coor.latitude = 39.915;

    coor.longitude = 116.404;

    BMKPointAnnotation* annotation = [[BMKPointAnnotationalloc]init];

    annotation.coordinate = coor;

    annotation.title = @"这里是北京";

    [mapView addAnnotation:annotation];//这个行为会触发- (BMKAnnotationView*)mapView:                       (BMKMapView *)mapView viewForAnnotation:(id<BMKAnnotation>)annotation

 

    [self.view addSubview:mapView];

 

- (BMKAnnotationView*)mapView:(BMKMapView *)mapView viewForAnnotation:(id<BMKAnnotation>)annotation

{

    BMKPinAnnotationView *animationView = [[BMKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:@"animation"];

    animationView.pinColor = BMKPinAnnotationColorGreen;

    animationView.animatesDrop = YES;

    return animationView;

 

}

 

2、删除标注

 

if (annotation != nil) {  

    [_mapView removeAnnotation:annotation];

｝

 

3、添加折线

 

   。。。。。

   CLLocationCoordinate2D coors[2] = {0};

    coors[0].latitude = 39.315;

    coors[0].longitude = 116.304;

    coors[1].latitude = 39.515;

    coors[1].longitude = 116.504;

    BMKPolyline* polyline = [BMKPolyline polylineWithCoordinates:coors count:2];

 

    [mapView addOverlay:polyline]; //触发下面的委托

 

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

{

    BMKPolylineView *polyine = [[BMKPolylineView alloc]initWithOverlay:overlay];

    polyine.strokeColor = [UIColor greenColor];

    polyine.lineWidth = 2;

    return polyine;

 

}

4、添加多边形

CLLocationCoordinate2D coors[2] = {0};将这个数组声明大一点就行了比如三角形就三个点。

在回调中通过 polygonView.fillColor = [[UIColor cyanColor] colorWithAlphaComponent:0.2];  进行颜色的填充

 

5、添加圆

 

   BMKMapView *mapView = [[BMKMapViewalloc]initWithFrame:[[UIScreenmainScreen] bounds]];

    mapView.delegate = self;

    [mapView setMapType:BMKMapTypeTrafficOn];

    CLLocationCoordinate2D coor;

    coor.latitude = 39.915;

    coor.longitude = 116.404;

    BMKCircle *circle = [BMKCirclecircleWithCenterCoordinate:coor radius:5000];

 

    [mapView addOverlay:circle];

 

 

／／委托

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

{

    if([overlay isKindOfClass:[BMKCircle class]])

    {

        BMKCircleView* circleView = [[BMKCircleView alloc] initWithOverlay:overlay];

        circleView.fillColor = [[UIColorcyanColor] colorWithAlphaComponent:0.5];

        circleView.strokeColor = [[UIColorblueColor] colorWithAlphaComponent:0.5];

        circleView.lineWidth = 10.0;

        return circleView;

    }

    returnnil;

 

}
