iOS调用百度地图（二）

可以借助title属性来绘制多个电子围栏

//添加预警区域覆盖物
- (void)addWarningOverlayViewAndAnnotationWithModel:(SiteelectFenceModel *)model {
    if ([model.electFenceType isEqualToString:@"1"]) {
        // 添加圆形覆盖物
        int electRadius = 100;
        if (![NSString isNull:model.electRadius]) {
            if ([model.electRadius intValue] < 30) {
                electRadius = 30;
            }else{
                electRadius = [model.electRadius intValue];
            }
        }
        BMKCircle* warningcircle;
        CLLocationCoordinate2D coor = CLLocationCoordinate2DMake([model.electCenter.lat doubleValue], [model.electCenter.lon doubleValue]);
        warningcircle = [BMKCircle circleWithCenterCoordinate:coor radius:electRadius];
        warningcircle.title = WarningTag;
        [_mapView addOverlay:warningcircle];
    }else if ([model.electFenceType isEqualToString:@"2"]){
        BMKPolygon *warningpolygon;
        // 添加多边形覆盖物
        CLLocationCoordinate2D coords[model.coordinateList.count];
        for (int i = 0; i < model.coordinateList.count; i ++) {
            SiteLocationModel *lomodel = model.coordinateList[i];
            CLLocationCoordinate2D coord = CLLocationCoordinate2DMake([lomodel.lat doubleValue], [lomodel.lon doubleValue]);
            coords[i] = coord;
        }
        warningpolygon = [BMKPolygon polygonWithCoordinates:coords count:model.coordinateList.count];
        warningpolygon.title = WarningTag;
        [_mapView addOverlay:warningpolygon];
    }else{//不去绘制
    }
    // 打点
    [self addLocationAnnotationWithModel:model];
}

大头针打点 单个

• (void)addLocationAnnotationWithModel:(SiteelectFenceModel *)model {
  BMKPointAnnotation *annotation = [[BMKPointAnnotation alloc] init];
  annotation.title = WarningTag;
  [_mapView addAnnotation:annotation];
  _annotation = annotation;
  CLLocationCoordinate2D coor = CLLocationCoordinate2DMake([model.lat doubleValue], [model.lon doubleValue]);
  _annotation.coordinate = coor;
  }

代理方法

//根据overlay生成对应的View

• (BMKOverlayView *)mapView:(BMKMapView )mapView viewForOverlay:(id <BMKOverlay>)overlay
  {
  if ([overlay isKindOfClass:[BMKCircle class]])

  if ([overlay.title isEqual:WarningTag]) {
  circleView.fillColor = [UIColor colorWithHex:0xFF0000 alpha:0.2];
  circleView.strokeColor = [UIColor colorWithHex:0xFF0000 alpha:1];
  }else
  {
  circleView.fillColor = [UIColor colorWithHex:0x6FB1FF alpha:0.2];
  circleView.strokeColor = [UIColor colorWithHex:0x6FB1FF alpha:1];
  }
  circleView.lineWidth = 0.5;
  return circleView;
  }

  if ([overlay isKindOfClass:[BMKPolygon class]])
  {
  BMKPolygonView* polygonView = [[BMKPolygonView alloc] initWithOverlay:overlay];
  if ([overlay.title isEqual:WarningTag]) {
  polygonView.fillColor = [UIColor colorWithHex:0xFF0000 alpha:0.2];

  }else{

  polygonView.fillColor = [UIColor colorWithHex:0x6FB1FF alpha:0.2];
  }
  polygonView.lineWidth = 0.5;
  // polygonView.lineDash = (overlay == polygon2);
  return polygonView;
  }

  return nil;
  }
